I will check this out... but I doubt it in my case. But I will check. thnks.
FYI ours was placed on the main line right underneath the outside water spigot. This is the main line from the community H2O supply. If the pressure is from municipal sources it should be their reponsibility. If you just want a reducer on your shower or inside the house chances are they will deny your application. They should have a plumber on retainer who could check it. The last thing they want to find out is that the H2O pressure is coming from the main lines into the houses. There could be a major lawsuit if more than one house is affected. Most HOA;s are about preventative maintenance. If your present it this way to them they should check it for themselves. Hope this helps. PS where are you? Are you in So. Cal.?
