I have a Wilkins 975xl backflow preventer. It is removed every winter and passes its test before every spring. That said - my sprinkle output is very weak. Each time I run the sprinklers I have to shut off the water coming from the Wilkins and open the three relief valves. This can be done in any order - once all three are open - I shut them off one at a time - open the water valve back up - and my sprinklers run just fine.....
Once done all 5 zones run normally. There are no visible leaves from the preventer.
Thoughts?
