Sprinkler System Winterization

uawsn(5)October 16, 2012

I am in Capital Region, NY and want to winterize my sprinkler system by myself.

I bought a Husky electric compressor: 20 gal, 4.3 SCFM @ 90PSI and tried once. I am having a couple of questions to ask for help:

(1) I blow out the air zone by zone. But even for one zone, not all the heads will pop up. Is the pressure too low ( I used 50 PSI max) or 20 gallon is still too small?.

(2) If there is still some water left (due to the size of compressor), will that be damaging?

(3) The air was used up quite soon, maybe 1 minute or 2. So I just reduce the psi to 0, wait for the compressor for 5 mins, then turn psi to 50 again. Is this method okay?

Thanks very much,

u,

Sounds good to me but then again I don't have to winterize. There are many past threads on this subject with the compressor size to use. I don't think any damage will result if some water is left behind as long as there is room for the water to expand as it freezes. Aloha
