Pressure Drop wierd effect
Wallies know water. So this is not a heating question exactly.
Is there a control I could put in our house water supply downstream of the 1" takeoff for the lawn sprinkler system [which is just after the meter] for the purpose of softening the effect of a sprinkler zone opening quickly.? Why? Well, the sudden pressure drop felt in the 3/4" house supply actually tugs open the Delta 17 pressure balance valve in the upstairs shower. The hot water starts running at a goodly trickle, for hours, at 4:30 AM. It's a waste and a source of mold. I mean this happens when the shower is not in use. It is at least 40 feet away from meter.
Valve is 3 years in service. It has had a slight drip. I will install all new cartridge parts tomorrow, which Delta very thoughtfully supplied.. But will not know result till Spring, of course. Odd thing. But it happens every time. The lawn system is just new this Fall. It has the usual pressure breaker [?] seen on all systems at the foundation. Thank you for any ideas. Joe
