Greg Booth Posted June 8, 2016 Report Share Posted June 8, 2016 The problem/question: whenever a faucet is turned on, there is a quick "spritz" of air/bubbles - happens at cold and hot water, and all locations in home. I have tried to diagnose (long distance) and learned the following: 1) The house is on municipal water - situated at the top of a hill in a residential area 2) Water pressure delivered at 75 psi 3) There is a pressure regulator, which I suspect is failing, as owner states pressure has declined over the past months 4) There is a multi zoned lawn sprinkler system 5) One sprinkler zone is piped before the pressure regulator 6) An outdoor leak in the pvc water supply was repaired about 2 months ago 7) A new water heater was installed about 1 month ago Owner says there is no expansion tank in the water system Any ideas would be appreciated........Greg Quote Link to comment Share on other sites More sharing options...
Marc Posted June 8, 2016 Report Share Posted June 8, 2016 Just curious: for how long has this been going on? Marc Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted June 8, 2016 Report Share Posted June 8, 2016 It well could be just O2 liberated from its watery captor. Like when you fill a closed hydronic heating system, air comes out for months. Quote Link to comment Share on other sites More sharing options...
kurt Posted June 8, 2016 Report Share Posted June 8, 2016 What kind of fixtures? I have a reason for asking. After that, what Fabry said. Quote Link to comment Share on other sites More sharing options...
Greg Booth Posted June 9, 2016 Author Report Share Posted June 9, 2016 The fixtures are Moen, basic style - all single lever in kitchen & bath. Problem existing for a couple of months, apparently noticed after the main-line repair. Thanks to all for replies.......Greg Quote Link to comment Share on other sites More sharing options...
kurt Posted June 9, 2016 Report Share Posted June 9, 2016 Ok, the issue I've seen isn't with Moen, although I suppose it could be. Has it subsided at all, or is it the same consistent condition after several months? Quote Link to comment Share on other sites More sharing options...

Bill Kibbel Posted June 10, 2016 Report Share Posted June 10, 2016 Are there anti-siphon vacuum breakers on the supplies to the irrigation system? (there should be 2 as you indicated one zone is supplied before the p-reg) They can be damaged when they blow out the lines incorrectly for winterization. The failure of the device (or lack of) can cause weird stuff to happen. Have them shut off the supplies to the irrigation for a while and see if there's any change.
