Hi folks,
Dunno if you've come across anything like this, but any help would be appreciated.
We just had a pump installed to supply the two bathrooms in the house and it's working great, except that sometimes when you use a hot water tap elsewhere in the house, that isn't plumbed to the pump, it starts pulsing. It keeps going on and off in one second intervals and has to be switched off.
It's scary, I didn't want to see for how long this can last because I'd imagine it's damaging the pump. The plumber doesn't seem to know what it could be but he's coming over next week to check.
Grundfos suggested that it might be air in the system, but we've had a flange fitted to ensure an air-free supply of hot water and we've done everything they've suggested to get rid of possible air in the pipes. (running hot taps everywhere in the house)
It's early days still but I'm not feeling confident that the plumber will know what to do and was hoping that someone might be able to point us in the right direction.
Thanks!
