Hi after i use my shower there is a humming noise from the pipes and the only way to stop it is if i run the other shower in the en suite bathroom. What could be the problem and how can this be fixed??
It can be water hammer. Water hammer generally occurs when you shut off a quick acting valve. This results into a loud sound like a bang and it is usually because of water’s energy expressing through sound waves instead of flowing. The other thing you are saying is that the sound stops as you turn on your another shower. Then It can say that the quick valve gets slow down, comes back to the older position so it put a stoppage to water hammer.
