Central Heating Over Flow Issue that's stumped many heating engineers :(

ok think overflow problem solved but shower is now redundant.

he said he could take the valve out - but i said leave it, because house needs to start drying, and i have downstairs shower.

Said solution is adding a new pipe and feeding off the cold tank, or for proper job adding second tank and feeding from that - same height as original tank so same pressure.

Any thoughts?

And basically I don't neccessarily want the top/best option, just something that works because as soon as this is sorted the house is going for sale

Yep - take his advice - equal pressures to a mixer shower is (obviously) the way to go - how 'correct' the plumbing for it is is up to your discression...

Plumbing dilemma sorted - now to work on the moral one

The just adding new cold water pipe to the tank that is up there already would be far cheaper, but I'm not sure if one tank of water would be enough for filling a bath etc

Seeing as my mains water comes in slowly, I dont know that it would refill quick enough as I was using it... I don't know if there's a way of finding out without trying that first

Can't try now as water in bath taps as well as shower are a trickle from the hot.

Filling a bath would be no different from what it was - so if you can do that without draining the tank then I expect it would cope with a shower from a single header, not ideal but it's the starting point.

Why has the hot become a dribble?

I guess when filling the bath I did it mostly from hot tap, so prob should still be enough and therefore enough for shower

I'll see what the price difference is between the two options. After all, as well as the moral issue, i could be living her for months waiting for a sale and completion.

The hot water on bath and shower has become dribble because of fitting the check valve. I was told it was likely this would happen - something to do with the pressure of hot and cold being different
