Hi,
I've seen a few threads about this, but not 100% sure on the answer for me. The F & E tank keeps overflowing when the hot water is on, its like a fast drip and then slows to a slow drip when its off. The water in the F & E is warm and the ball valve is working as it should. When the tank fills, the level is covering most of the ball and the valve is definitely closed. I assume this means it is filling from the pipe at the bottom?
The F & E has 3 pipes, one at the bottom which gets warm, one at the top which is the cold water (coming from mains supply as i cant see it connected to the cold water tank) and the pipe going over the top of the tank.
The F & E tank is about a foot or so lower than the cold water tank. I live in a town house, the boiler is in the kitchen on the middle floor, the hot water tank is in an airing cupboard on the top floor and cold water and F & E tank is is the loft.
I emptied the F & E tank down to about a third full where it looks like the level has been for years (a clear line around the tank) and it fills up (a rise of about 20cm) the next time the hot water is on if the pump is set to speed 2 and within a couple days if it is on speed 1 (we have the hot water come on twice a day). I thought i had fixed it by switching to the lower speed, but it was not to be.
The hot water coming out of the taps is not dirty so unsure if the coil in the tank is damaged. We had a new 3 way valve and pump fitted last December and things appeared fine until about 2 weeks ago.
We have not had the heating on recently so unsure if this would affect things.
Is there anything else (simple) i can try before calling in a heating engineer?
Thanks
