Hi,
So I’m looking for a little advice/guidance please.
I have a F&E system which is dumping hot water into the F&E tank via the vent pipe.
I moved into the house 18months ago, last winter being my first in the house.
The downstairs rads were like warm while the upstairs were ok. Eventually the boiler stopped working. A engineered came round and changed the pump from an old grundfos to a grundfos alpha 2L 15-60 130.
That sorted the problem for a week or so, then the boiler stopped again.
Called out a different engineer, who diagnosed the problem as a blockage and said the Pump never needed changing. He unblocked the pipe (the one entering the bottom of F&E tank). He said the system was dirty and would need a flush at some point. (Not done yet)
Unblocking of the pipe sorted everything out for a good few months. The next problem I have is the F&E tank filling with hot water and sending it pouring out the overflow. It’s pouring in like a fully open tap.
When I disconnect the circulation pump supply, the pouring into the F&E tank stops.
Hoping that it is another blockage I have just filled the system with x400 cleaner but can’t pump it around the system as the pump needs to be disconnected.
Any advice on my issues?
I’ve checked the direction of the pump, it’s ok.
The actuator is in the mid position. All pipes before and after the pump are getting red hot.
Any advice would be much appreciated.
Cheers,
