Before You Begin
The first matter to do when beginning a sprinkler system of rules winterizing labor is to tax the unspoilt style to release water from your particular system . There are two principal way to go about this : One is to enfeeble water system from the valves , and the second is to employ an melody compressor to bollix piss out of the irrigation pipework . If you are wonder when to winterize sprinkler organisation , manysprinkler systemmanufacturers recommend that homeowners drain their organization when temperature dunk to 30 stage Fahrenheit .
You ’ll also need to determine the character of drain valve your scheme utilizes , as this dictates whether draining is reflex or manual . Manual - drain sprinkler heads have check valve on them , and they require that you pull a few lever to get things moving .
Once you cognize what case of system you have , you could accomplish almost all the necessary winterization on your own with the information below — though , of course of action , you should brush up the owner ’s manual of arms and keep it nearby for denotation .

STEP 1: Turn off the main water supply, and turn off the backflow preventer if your system has one.
First , turn off the main water supplyto the house , which is often found near your water beat .
If your sprinkler has manual drain valves , also shut off the valve on the backflow preventer . A backflow machine , typically located near the water main from which the sprinkler water is drawn , prevent pressurized , potentially contaminate water from mixing with the drinkable water provision .
If you ’re not using potable water for irrigation , your organisation may not include a backflow gadget . If it does , turn it off via two valve exclude - off hold on the separate pipes flow into the gadget . Just turn these orthogonal handles clockwise one - twenty-five percent to one - one-half bout ; use plyer if the valve are too tight to rick by helping hand .

STEP 2: Drain any water remaining in the irrigation system.
Your next move depends on the type of drain valve you have .
STEP 3: Open all of the drain valves.
After empty the mainline via automatic draining or manual draining , make certain that no water remains around the various valves that could expand when temperature throw away . Depending on your system , you may have a “ steam boiler waste pipe valve ” or a “ stop and waste valve , ” which will bend off the localwater supplyand also appropriate for drain that tobacco pipe .
Locate this valve ’s drain cap and start the valve to run out the last of the H2O left between the irrigation organisation and the backflow machine . If you plan to lease professionals to perform a reversal - out , move on to Step 4 . If you ’re expect only to debilitate the tobacco pipe , you may proceed to ill-use 5 .
STEP 4: Blow out the irrigation pipes with an air compressor. (We recommend hiring a professional for this step.)
take on that your sprinklers are relatively new and put in correctly with the irrigation pipe splatter down toward the valves ( where water can issue at the lowest point in the system ) , gravity will guide nearly all the water out after you ’ve free the pressure in the mainline .
But it ’s hard to know for sure that there ’s not some left behind — say , caught around a inclination or curve in a pipe that has shift since installing . For this grounds , experts recommend call in a professional to take a further precaution that will let go any last lingering water remaining in the sprinkler scheme : blowing out the organ pipe using anair compressor .
You might already own an melody compressor and use it to power your nail guns and other air peter ; perhaps it even boast the capability to generate more than the recommend 50 pounds per square inch ( psi ) needed to brighten a sprinkler system ’s worth of flexible polythene pipe , or the 80 pounds per square inch needed to blow out set PVC pipework . Still , expert advise against DIYing this step for a few reason :

After the professionals connect their air travel compressor to the hosiery leading from the water main supply and bluster out your sprinkler system zona by zone , they should also end the master shut out - off valves . They ’ll also drain any water that accumulate around your backflow preventer ( the gadget that isolate the system ’s backflow and maintain it secure from harm ) .
STEP 5: Insulate any system components that are located above ground.
If any parts of your sprinkler system — include pipes , backflowing preventers , and main shut - off valves — are above ground , it ’s a good estimation to isolate the exposed parts . Local computer hardware stores normally offer foam insularism taping , foam piping cover , and other winterise shelter .
STEP 6: Consult your owner’s manual for recommendations that are specific to your system.
Some systems ask that valve be lay in indoors and pipes capped during the winter . Consult your proprietor ’s manual to find out the recommendations for your fussy sprinkler organization .

If your sprinkler system is on a timekeeper , be sure to shut it off for the time of year . ( think back to reprogram it in the spring ! ) It ’s also possible that you have a “ rain mode , ” which halt thesprinklerswithout turn off the timekeeper when you get hastiness during the regular time of year . you’re able to sprain rainfall mood on for the winter to prevent the system from watering . This way you’re able to avoid exit the organization off and losing the programmed options on yoursprinkler controller , which would leave you with the hassle of reprogramming add up give . The sensing element use such a small amount of vim that leaving it on through the wintertime wo n’t typically bestow much to your energy monetary value .
