Hi all,
I've had a dual, negative head (salamander) shower pump installed for a while. The hot is fed from the hot water cylinder, the cold from the same cold water tank that feeds it i.e. they have the same head of pressure. The cold water tank has plenty of capacity BTW. This has run just fine, but just recently the pump has started coming on in short bursts after the shower valve has been closed. Does anyone know what might be causing it? I'm thinking it might be a slow leak, though I haven't managed to find any evidence of this so far. Any help is much appreciated...
