    I've got a valve that makes a loud clacking/buzzing noise when it is activated. It sounds like someone is banging the pipes in our basement. Also, the pressure is reduced on this station, and it is submerged in water when it operates.

    1. Is this because there is a clog, a leak, a bad valve, or all three?

    2. What should I do next?

    I am going to guess that it is a Pressure Reducing Valve (PRV) and it is in need of replacing...but we need more info to be sure...a pic would help...

    Picture coming soon

    I am trapped in a dishwasher repair, but will put a picture up soon. It is old, and it has a solenoid and can be manually opened as well.

    I have experienced this many times. Often it is the flow control on a valve is turned down too far and the valve can't open properly. This makes the diaphragm bounce up and down.
