backflow preventer

I turned my backflow preventer off last week ahead of a Texas freeze. I turned the water back on today, and water is leaking out of the place where the lever handle attaches to the pipe (see picture). No water is coming out of the bonnet. Any insight on why this is happening and the best way to...

People in my town, due to Ida, asking about backflow valves. In my home I have a JR Smith 7150. You can't really rely on the plastic one-way flapper. It also has a spade-type manual gate valve turned by a wheel. You have to make the decision whether and when to shut down your waste discharge. I...

I have a claw foot tub with a handheld shower. The handheld shower seems to have a misbehaving backflow preventer valve. When the pressure gets to high (not really very high), the water is simply shut off. I'm looking at it and it seems the backflow preventer is a fairly complicated mechanism...

Hello, I have been driving myself crazy trying to figure this one out the last couple of days, and I am hoping someone here might have some advice before I call a professional. I have a relatively small lawn (~800 sq ft) with about 12 pop up sprinklers, and two days ago I moved a sprinkler head...

I have a small cabin in a 12 cabin community which is spring fed (spring flow is about 5 gpm). The water flows from our spring box into a 5000 gallon storage tank. The community was built in the 50's and the water system was originally designed to work off of gravity flow alone. In the upper...

Hi, Newbe here. I have a 3/4" Febco 825Y backflow preventer that is making moaning - fog horn noises on a couple of zones in my sprinkler system. I have read that this won't do any harm to the system but is annoying. Especially at 5am. I have read that the pressure may be too low and causing the...
