Here's a problem that's confusing me...
We've had soem builders working on a room we're turning into a kitchen. Lots of heavy work, removing floor, render etc. In the process, they have removed the old rad, cut out some old pipework and capped the ends.
Since yesterday afternoon our Feed and Expansion tank for the Central Heating has been filling with a steady trickle. So over 24rs that's got to be alot of water. So there could be a few causes. I've eliminated a few:
1. faulty ball cock: this would presumably result in the tank filling and overflowing. This isn't happening. Water level is still well below overflow and at normal level.
2. Air In system being replaced: This is probably the most likely candidate, as i'm pretty sure there was air in the rad they removed and also for a while the boiler was cutting out. However i've bled all the rads (no air) my thinking is that after over 24hrs surely any air would have worked its way out with the amount of water that must have entered the system.
3. Water Leak: I'm coming to the worrying conclusion that if the above 2 aren't happening then there must be a water leak. However i've inspected the house and can't see any signs of water leaking. I've been through pretty carefully and would have thought that the for amount of water going in any leak would be pretty obvious! There's only 2 places i can't follow the pipework. One is where it disappears under a concrete floor and the other is from the 1st floor down vertically though a downstairs wall.
All radiators apart from one seem to working although i'm confused why this one isn't, possibly something's shifted and it's blocked? There are a couple of very slightly leaky valves but we're talking minor drops, definitely nothing close to a trickle. The other thing is that not all rads are warming quite as much as usual but apart from the one they all have heat. I may need to rebalance the system.
So i'm left completely flumexed! HELP! We're on a water meter so don't want to waste water unnecessarily.
Thanks, i hope someone out there can shed some light on what might be causing this.
