Hi,
I am having trouble with my Feed & Expansion tank (smaller tank) in the loft overflowing constantly and water continually pouring out of the overflow pipe into the garden.
(this is off the back of this post, but the cause is not the valve //www.diynot.com/forums/plumbing/header-tank-waste-exit-pipe-leaking.324970/#2410678).
I have narrowed it down to the expansion pipe that feeds into the tank from above causing the overflowing. The water seems to be dumped out a couple of minutes after the heating has gone off (not a constant drip).
I placed a bucket under this and with the heating having been on for 3 hours (2 consecutively) the bucket caught approx 3/4 litre of water. This would be more than enough to cause the overflow. Any idea why this much water is coming from the expansion pipe (and I presume coming from the immersion tank)?
Things I have tried (thanks to this forum):
1) changed the ballvalve on the tank (I first thought this was leaking).
2) lowered the speed on my Celsia pump from 3 to 2.
Could there be a problem with the tank or coil itself?
Setup:
FE tank in loft above immersion tank in bathroom.
Large cold water tank above FE tank in loft.
Gas boiler.
The bend in the expansion pipe sits approx 23 inches from tank water level.
Any ideas would be much appreciated.
thanks alot.
