Have just replaced an 8 year old salamander RHP75 pump with a new one as the old one was making a horrbile noise.
When i turn off the hot tap the pump continues to pulse (on/off) and the only way to stop it is turn the pump off and on again or turn the tap on again and off slowly. Appears that turning the tap off quickly causes the problem.
Any one know what's causing this and how to stop it (other than telling every one to turn taps off slowly)
Pump feeds a bath in one room and sink, shower and toilet in another room.
