Spring Start Up and Winterization Instructions for Krupske Sprinkler Systems Installed in 2010 and Before

Spring Start Up Instructions

U009AQT RPZ installed for Spring

An RPZ valve correctly installed. (Notice the test ports are pointing up)

Watts U919AQT RPZ

Step 1 Reinstall RPZ valve back on to the piping on the outside of the house. The arrow on the side of the valve shows the flow of water. The arrow should point to the pipe that goes into the ground. The 3 test valves on the RPZ face upwards, the big drainage hole faces down. When connecting the valve to the unions make sure the O-rings are still in the groove on the RPZ.

Step 2 Close the drains and turn the water on. Plug the control timer and pump in if they were unplugged for the winter.

Step 3 Run each station for 2-3 minutes and check all heads to make sure they are spraying correctly. Sometimes the snowplows damage the heads or the grass grows over them.

Step 4 Call us for the RPZ certification.

Winterization Instructions

Winterized U919AQT RPZ

Notice the handles are at 45 degrees and there are bags over the open ends

Step 1 Shut off water valve for sprinklers.

Step 2 Go outside and remove RPZ valve. This is done by loosening the unions on each side of the valve and lifting the unit out. Bring the RPZ inside for the winter.

Step 3 Turn valve handles at a 45 degree angle on the outside piping. This is 1/2 on and 1/2 off. This is very important or the valves will crack and you will pay for new ones.

Step 4 Place plastic bags over the exposed ends.

Step 5 Locate sprinkler drain. If located inside, open and drain into a bucket. If located outside, open and leave open for winter.

Step 6 If you have a booster pump for the sprinkler system only, unplug at this time. Failure to do so may result in pump damage not covered by warranty.

Step 7 Program all stations to run for 5 minutes each. When cycle is over turn off clock. You will not see or hear anything happening during this last step.
