Quick & Dirty Summary*

"Laterals" are what we name the pipes or tubes that are positioned between your on/off valve and the sprinkler heads. For instance, if you are using computerized solenoid valves the pipes between the valves and the sprinkler heads would be called "laterals" or "lateral pipes" or "lateral tubes," and many others.. Because the water is best pressurized in those pipes when the sprinklers are grew to become on they don't need as a lot energy, so the laterals most often use a decrease quality pipe to save money. In temperate zones it's conventional to make use of Cl 2 hundred PVC pipe for laterals. PVC pipe holds up smartly to widespread use of the irrigation system and better water pressures conventional of the temperate Zones of the US. Polyethylene is turning into more and more common in temperate zones additionally, due to greater advertising and marketing and ease of installation, however there are still some questions as to how neatly poly will hang as much as the more widespread irrigations and better water pressures not unusual in those climates. In cold winter areas it's conventional to use Eighty or 100 PSI polyethylene "irrigation" tube for laterals as poly holds as much as freezes higher than PVC. Consider the use of a better A hundred and sixty PSI stress rated poly tube if the static water pressure is higher than 60 PSI. As water strikes via a pipe or tube it loses stress due to friction. The allowable stress loss in the laterals is in most cases saved beneath 4 PSI, with 6 being the utmost recommended when you've got a high static water strain, or economic system is extra essential than quality. Higher stress loss could cause poor uniformity of water coverage and lead to "dry spots." Lateral pipes should be buried a minimum of 10″ deep to give protection to them from damage from lawn aerators and automobiles riding over them.

Types of Commonly used Irrigation Pipe

Definition: Lateral Pipe or tube. In irrigation, the pipes/tubes between the zone keep watch over valves and the sprinkler heads or emitters are known as "laterals." These lateral pipes or tubes aren't pressurized except the valve is open and the sprinklers are running. Lateral pipes are generally topic to less water strain, surges, and pressure. So a less sturdy and less expensive pipe subject matter is also used for them. If you discuss with your local warehouse ironmongery shop you may in finding that they use the identify "department" pipe for laterals.

Two sorts of pipe/tube are usually used for sprinkler system laterals, polyvinyl chloride pipe (PVC), and Polyethylene tube (Poly). Both are sorts of plastic. PVC is in most cases white or gray color and semi-rigid. Polyethylene is normally black and is flexible.

PVC is the kind most regularly utilized in heat wintry weather climates. PVC pipe is rated via two other programs, the first is the "class" system (Cl) the other is the "agenda" system (SCH). It isn't conceivable to say that one is always higher than the other. Schedule pipe is rated by means of the pipe's wall thickness, while magnificence pipe is rated by means of the pipe's operating pressure. All PVC pipe has uniform outdoor diameter sizes. So pipe of the same dimension has the same out of doors diameter, regardless of which type or ranking they are. This permits the fittings that sign up for them in combination to be a common dimension, the similar fittings will have compatibility they all.

All PVC will have to be protected from daylight. Some sorts of PVC are advertised as "daylight resistant." My enjoy is that they last more than usual PVC, however will nonetheless slowly degrade in sunlight. The UV rays in sunlight causes the PVC to turn into brittle, it is going to sooner or later grow to be so brittle that just tapping it's going to reason it to fall apart. How long it takes depends upon how intense the UV in the sunlight is. So you could bet that in Arizona, with intense sunshine, it will be a huge problem. But did you know dim winter sunshine reflected off snow can provide even more UV publicity? That's why you get sunburned so easily when skiing. Same with prime altitude spaces (less setting permits more UV through.) The harm is permanent and now not reversible, so if the shop you purchase it from keeps it outside, you might want to query how long it's been sitting out within the solar! A couple of months saved within the solar in maximum climates is not a problem. UV damaged PVC has a tendency to show a noticeably brownish "sunburn". If you employ PVC above flooring you should offer protection to it from sunlight. Three coats of exterior latex paint turns out to do a reasonable activity. Better but, put foam pipe insulation around above ground PVC pipe and "kill two birds" with one stone.

Most PVC pipe is hooked up together the usage of "PVC fittings" which can be glued in position. The fittings are usually rated as SCH 40 (same old white PVC fittings), some are to be had as SCH 80 (stronger and generally grey colour.) Sometimes PVC pipe has threaded ends just like metal pipe. PVC pipe and steel pipe have the same outdoor diameters, and are interchangeable and metal fittings will are compatible onto threaded PVC pipe & vice versa.

As of 2014 when I am writing this web page update they've just offered slip together "push fittings" for pvc that do not use glue. These becoming use o-rings or versatile seals to forestall leakage, and a locking instrument with enamel that grips the pipe to hold it within the best. These slip fittings are removable the use of a different software. I have no idea how well these will hang up long term. As with all connectors that use flexible seals, the seal subject material quality is key to how lengthy the life of these fittings might be.

Poly tube is usually used in spaces with chilly winters (the place the soil freezes,) and is also used in special scenarios that require a extra flexible tube be used, akin to very rocky soil. High density polyethylene (HDPE) with high pressure rankings is much more extensively stocked in home and irrigation retail outlets than prior to now. New "push fittings" for poly tube that are universal and don't require clamps make set up a lot more straightforward and sooner. Both of those trends have ended in higher use of poly tube in all areas, irrespective of climate. Poly tube doesn't ruin as easily if water freezes in it. Poly tube is more forgiving in rocky soils (giant rocks, like granite boulders) as it's less prone to crack if it is put in towards the facet of a large rock.

Poly tube is rated via a system of "SDR" ratios, on occasion classified simply "DR". The decrease the SDR quantity, the more potent the tube is. HDPE poly is often rated for 80, 100, 160, 200, and 250 PSI running strain or working stress (NOT burst stress!) The most cost-effective type of poly is offered as "irrigation pipe" and is rated for Eighty PSI (every now and then 100 PSI), it is often used for low-pressure laterals on irrigation techniques. Remember the lateral is best the pipe after the valves, between the valve and the real sprinkler head. All poly tube of the same dimension may have the similar INSIDE diameter.

PEX tube is a form of poly tube this is much more potent, but in addition dearer. It is being used more and more as a substitute for copper plumbing within properties. It is built to the similar out of doors diameter as copper tube. However it has a thicker wall than copper tube, so has much less drift capability in a given measurement of tube. It could also be used for irrigation laterals, however tends to be too pricey for most eventualities.

Traditional "insert fittings" used for poly tube are often known as "barbed fittings". Insert fittings shove into the pipe and feature barbs to assist cling them in position. Do not depend at the barbs to hold the tube on the becoming! You wish to also set up a stainless steel clamp around the tube where it suits over the barb with the intention to securely grasp the tube on the barb. (Exception: sprinkler risers the use of particular "twist on" barb fittings are designed not to require clamps.)

A more recent fitting type used with both poly tube and PEX are "Push fittings". These fittings would not have a barb, the tube "pushes" into the precise and locks in position. These fittings use a flexible seal that stretches across the tube to create a water tight seal even with the not up to uniform outside diameters found with poly tube. The "locking" function of these fittings is the result of a collection of stainless-steel teeth that "bite" into the comfortable poly tube to carry it in position. Thus those push fittings allow quick and simple tube assembly with out the want to install separate clamps on each connection. Push fittings are extensively utilized with PEX tube. Warning: some push fittings made for irrigation use are NOT beneficial to be used on mainlines and are just for irrigation system laterals. I do know this web page is set laterals, however I sought after to provide you with a warning to make sure you test this if you want to use them on a mainline!

Saddles are ceaselessly used on poly tube laterals (most don't seem to be made for use on mainlines!) Saddles make a handy guide a rough and simple technique to connect the sprinkler risers to the lateral pipe. They work smartly and are very popular due to the convenience of set up, particularly when connecting a smaller diameter riser to a larger diameter tube. If you utilize a saddle that requires drilling throughout the tube you should definitely flush out the tubes extremely smartly prior to putting in any sprinklers as there will probably be a variety of small pieces of the tube left inside of. Those little fragments of polyethylene will clog up your sprinklers and nozzles! You don't need to spend hours cleansing brand new sprinklers. If you've a drip system the fragments will smash the emitters making them trash.

Maximum Operating Pressure

Background: The stress ratings for pipes and tubes are in line with the utmost occasional surge stress allowable within the pipe or tube. So this implies a pipe rated for Two hundred PSI must no longer be subjected to 2 hundred PSI pressures regularly. Almost all pipe/tube manufacturers recommend that the pressure rating of the tube be double the traditional strain found in the water system. So to restate what this means, if the normal water stress is One hundred PSI, the pipe or tube manufacturer calls for that you use Two hundred PSI rated pipe. The ranking is NOT the traditional pressure for the pipe or tube! ("Burst pressure" isn't the same factor because the pressure rating. If a burst stress is given, suppose that is 3x the normal system stress. So 300 PSI burst pressure = One hundred PSI customary stress.) The explanation why at the back of this bizarre labeling system is that water pressure surges are quite common and they can simply double the pressure in a pipe or tube! For instance, when a normal automated irrigation valve closes it can create a water strain spike that doubles the strain. Thus a valve closing can be an "occasional surge". This strain spike is named "water hammer".

Pressure ratings for lateral pipes: In the case of laterals, the lateral pipe/tube is positioned after, or downstream of, the valve. Fortunately the strain surges brought about by means of valves final might be confined to the mainline, which is upstream of the valve. This is why sturdy, prime strain pipe is needed for mainlines (see the web page on mainlines.) Pressure surges are much much less likely in laterals, and once they do happen lots of the surge strain is harmlessly launched through the sprinkler head nozzle or drip emitters. For this reason why the lateral pipe can have a lower strain score.

Using PVC Pipe:

The business standard for PVC lateral pipes is to make use of CL 200 PVC. Many householders are tempted to use the CL One hundred twenty five PVC pipe because it is affordable, nevertheless it breaks easily they usually continuously be apologetic about the usage of it later. I've noticed that starting across the yr 2000 most hardware stores began stocking Cl 200 pipe and stopped selling CL 125. I imagine they have been losing too much cash on returns of cut up pipe. There is a great chance you are going to split open Cl 125 just transporting it home! If you'll't find CL 200 PVC then use SCH 40 PVC, which is rather stronger. (For pipe below 6″ diameter. Starting with 6″ and bigger pipe, Cl Two hundred is actually stronger than SCH 40. As SCH 40 pipe sizes get better the stress rating is much less. This is because the SCH Forty standard is in keeping with pipe constructed from metal slightly than plastic.)

Most home-owner programs have the pipe buried too shallow, incessantly 6″ or less. If you install it less than 10″ deep you might be asking for trouble. Remember PVC is brittle and can easily cut up with even a slight nick from a shovel while gardening. Likewise a lawn aerator will make Swiss Cheese out of a 6″ deep pipe. While PVC doesn't float as dangerous as poly, a 6″ deep pipe will ceaselessly drift up throughout the primary wintry weather, especially if the soil is saturated with water. Thus a pipe put in at 6″ may well be 2″ deep the following spring. I've seen many actually drift all the manner as much as the skin! 10″ of grime over the pipe helps keep it down the place it belongs.

Most execs, myself incorporated, avoid using 1/2″ size pvc pipe. It has very low glide capability, is ceaselessly now not to be had in Cl 200, and has a very small inside of diameter, making it plug up easily. It is really easy to partially block the float via 1/2″ pvc pipe by way of the usage of an excessive amount of glue on the fittings. This can seriously have an effect on the efficiency of your sprinklers! 3/4″ is worth the additional worth.

Using Poly Tube:

The business usual (sadly) for poly tube seems to be to use the super affordable 80 PSI poly irrigation tube for laterals. This is partially as a result of water pressures have a tendency to be decrease within the spaces where poly tube is historically used, partially because irrigation isn't needed as a lot of the 12 months in the ones areas, so the tubes are empty more of the time and don't get as much "wear". (To explain, every time the system is grew to become at the pressurized water in the tubes "stretches" them just a bit, over the years this reasons stress screw ups in the plastic.) Note that poly tubing is now being pushed to be used in areas outdoor the traditional "cold weather" areas the place it was previously used. I would be wary about the use of the low 80 or A hundred PSI rated poly in areas where static water pressures are above 60 PSI. It might be higher to pay more for One hundred sixty PSI rated tube in areas the place irrigation is heavily used.

Often poly tube is plowed into the soil with a "vibratory plow" system, usually 6″ deep because that is speedy and cheap. Unfortunately if you happen to install the tube 6″ deep after which aerate the garden you are going to poke holes in it. Plus 6″ deep tube is simple to stick a shovel through when gardening. Finally shallow tube tends to "drift" to the surface in the wintry weather when the water is blown out of it, especially if the ground will get saturated with water. You may plow a tube in at 6″ and uncover it's 1″ or 2″ deep the next spring, especially in case you didn't get a just right crop of grass growing over with thick roots to hold it down. I like to recommend poly tubes be no less than 10″ deep. All however the most cost-effective plows can install it 10″ deep, the plow just goes in somewhat slower.

Decide which kind(s) of pipe highest suits your wishes and make a note of it to your Design Data Form.

Lateral Pressure Loss:

We will resolve the real sizes of these pipes later the usage of the stress loss worth that we determine here. So that is the most important worth!

For most residential sprinkler techniques on City dimension so much a lateral stress loss price of 4 PSI will paintings great. It provides a pleasing stability between value savings and performance and is a secure figure to use with any type of sprinkler. I'd start with Four PSI for this value. If you find later that you need to lift it, come again and read the rest of this web page earlier than you do. If you make a decision you wish to have to make use of a lower value you'll achieve this without problems.

Note: You can skip right down to the "pencil" emblem close to the ground of this page if you're going to use 4 PSI in your lateral pressure loss value.

At this level in the design we want to make fairly of an "educated guess" for the lateral pressure loss. However there's a tenet for max allowable strain loss, so we will be able to use that as a starting point. This rule is: The lateral strain loss may by no means be more than 20% of the sprinkler head or drip emitter's operating stress. The sprinkler or emitter working pressure is established for us by way of the manufacturer, and you should have entered it on your Pressure Loss Table already.

Sprinkler Head Pressure x 0.20 = Maximum Lateral Pressure Loss

Example:Say the sprinkler heads we need to use have an operating pressure of 30 PSI. Then the lateral loss is probably not more than 6 PSI (30 x 0.20 = 6 PSI). Therefore we make an informed bet that a lateral strain lack of 6 PSI will work.

No doubt some are wondering why the lateral stress loss is proscribed to twenty% of the sprinkler or emitter operating pressure. This is an business standard for restricting the variation in performance between the sprinkler heads or emitters managed by way of the same valve. We know that the first sprinkler after the keep watch over valve will possibly (but now not all the time, see final paragraph beneath) have extra water stress than the furthest sprinkler from the keep an eye on valve. After all, the water has to go through a lot more pipe and fittings to succeed in that last sprinkler, so a lot of power goes to be misplaced getting there! Since both sprinkler and emitter performance is at once associated with water stress it is important to restrict the strain distinction between the first head and the final. Otherwise the first head might flood the world round it with water sooner than the last head even were given the realm around it rainy. I've observed poorly designed sprinkler systems where the grass is darkish green by way of the valve, and will get yellower and yellower as you move towards the final sprinkler! This is much more crucial with drip methods. I keep in mind a Eucalyptus tree farm I visited a few years back, the place they'd planted long rows of timber for firewood manufacturing. The first bushes (next to the valve) in each and every row had been two times the dimensions of the timber on the other end of the row! All for the reason that first timber had been getting a lot more water.

Now I assume I need to explain why the last sprinkler head on a line may no longer have the lowest running stress. There's just one scenario I can bring to mind where this may occur, and that is the place the sprinkler system is put in down the side of a steep hill. If the valve and primary head were on the best of the hill and the remaining head used to be on the bottom, then the added pressure that effects from the elevation trade (gravity provides power) might be nice sufficient to cancel out all of the pressure loss in the pipes! More on elevation adjustments and strain loss in the subsequent page of the sprinkler design tutorial!

Enter the Lateral Pressure Loss on the line categorized "Laterals" of your Pressure Loss Table.

Sprinkler Risers:

Sprinkler risers are what connects the sprinkler heads to the lateral pipes or tubes. Some other people imagine them a part of the lateral, others believe them a separate a part of the sprinkler system. They are in most cases flexible to permit the sprinkler head to move without breaking the lateral pipe. That's a pleasant feature to have whilst you pressure over a sprinkler with the automobile or hit a sprinkler with the mower. The better quality sprinkler risers, referred to as "swing risers", have jointed palms that allow the sprinkler to be moved up-and-down in addition to side-to-side, which allows you to alter the height and position of the sprinkler. To simplify issues a default strain loss price for the sprinkler risers is constructed into this Tutorial. (Hurray! Finally, something you don't want to worry about!) So as long as you employ this instructional in your design and a relatively same old riser in your sprinkler heads, you don't need to worry concerning the pressure losses.

What's a reasonably standard riser you ask? A standard riser would be a PVC swing joint the use of pipe and fittings the same dimension because the sprinkler inlet, any of the poly tube risers commonly know as "Funny Pipe®", "swing pipe" or equivalent (stay the riser tube lower than 18″ long), or Cobra Connector® (keep them less than 12″ long). Don't fear about those riser names for now, additional info on risers will come later. In reality, now would be a good time not to worry about risers in any respect! I handiest mention them here as a result of other folks get to this point and ship me emails telling me I've made a grievous mistake via leaving them out.

Winterization:

In most puts above floor pipes must have insulation round them. Even right here where I am in sunny temperate Southern California we every so often get enough of a hard frost to freeze our above flooring pipes, so I put insulation around mine simply to be safe. One 12 months we had a really laborious frost here, and it split open 1000's of backflow preventers that weren't insulated. It was an excellent year for backflow preventer manufacturers. Prices skyrocketed all over the United States due to the call for!

I've written a separate instructional on techniques to winterize your sprinkler system that you simply must learn if your irrigation system will probably be in an area where the ground freezes in wintry weather. You chilly weather folks wish to provide for some means of casting off the water from the pipes or tubes. While poly and PEX are more proof against freezing harm, they nonetheless wish to be tired or blown out with air in spaces the place the bottom freezes. If water freezes cast in any pipe or tube, PVC, poly, PEX, copper, brass, even steel, the pipe or tube will break up open!
