Leaking Water Tank Help

[Doomsnite]

Hello

We have a condenser boiler downstairs with the water tank upstairs. We have water dripping constantly out of one of the pipes at a rate of a bucket full every 2 days. Before we call a plumber, I just wanted to see if there is something I could be tightening to make it stop but dont know what I am looking at!



The bigger picture shows the leaking pipe in relation to the rest of the pipework.

The smaller picture shows where the water is coming out in the red circle. The yellow circle shows where there is a square nut thing which could be tightened. its one of those you can use with a spanner or a special key. The blue circle shows the only other point on the pipe where I think it could be tightened with a spanner.

Which of these, if any, should I have a go out? Any help and advice appreciated! :smile5:

carefully nip up the yellow circled one with a spanner

:iagree: Don't overdo it! There's a lot of water behind that drain-off!

Thanks. Is there a way to shut the water off behind it somehow?

Also why would it suddenly loosen, we never touch it ?

This one of the best posts I have seen for ages - photos and well presented
simple straighforwards advice in return. Fittings just leak sometimes thats why
we are all in business I suppose. centralheatking

it might still drip even if you tighten it a bit but good luck .

Why is that, what exactly is it for? It has never leaked in the 5yrs ive been here until now. Thanks all

Worst case its a drain down and re washer.

Do you see the valve bottom left with the red tag attached? Turn that off, open any hot tap till it stops running then close the hot tap. You should be able to nip it up and then control re-pressurising the system via the 'red tag' valve! If you're feeling brave you can even try removing the drain-off spindle and renewing the rubber washer on the inside ... Alas these are usually soldered without removing the rubber sealing washer which doesn't do them any good at all!

I'm assuming its an unvented cylinder judging by the stopcock, pressure reducing valve and tundish!

I missed the above before I tried it. Just tightened it a half turn and seems to have done the trick, the constant drips have stopped. Have left the bucket under there for the day and will check later if anything else creeps out. Thanks all!

Tell you what that is one on the neatest cylinder cupboard pipework set ups I have seen on UKPF for a long while, good on who ever did it, bet someone will find a fault somewhere.

No faults but an observation or two. Yes it's neat, everything to the sides so easier to maintain and replace if needed.

Initial length of d2, looks less than 300mm.

Insulation.

any heat lost warms the house and cant see an issue really with that one, esp if the lady of the house uses it as an airing cupboard, as modern cyls dont leak a lot of heat to dry her clothes

Well spotted simonG looks about 200 just above skirting although decieving with carpet folded.

Always easy to be critical

I've insulated pipework in cylinder cupboards, filled in the paperwork, photographed it and then pulled all the insulation back off at the request of the customer.
