Winterizing tips, refer to the
picture above. All you'll need is a screw driver.
When the temperature is going
to drop below 32 degrees:
• Shut off water supply valve
to the sprinkler system. This is the handle on the copper pipe that
goes outside to the back flow preventer. Alternately the drain may be
on the outside of the house under the back flow preventer Open the
drain next to the preventer (you may want to hang a bucket under it).
• Go to the back flow preventer
This is the device located just outside the house on the copper pipe
for the sprinklers. Open the the test cocks. PVB Valves have two test
cocks. RPZ's have four.
• With a screwdriver, turn the
test cock one quarter turn. The slot should be parallel with the test
cock. There are two shutoff handles on the PVB & RPZ. Open and
close each one 3 times, leaving them one half open when done. Shutoff
handles only turn ninety degrees from full open to full close. Lightly
tap on the back flow preventer four to six times to shake out any
remaining water.
