Help with identifying make and model of my water tank

[DanShaw]

Hi all

I hope someone can help me identify what my tank/water heater is. Ideally I'd like to find out make and model and look up an instruction manual/find out more about it. If it helps I live in a small block of flats (6 flats) that were built mid-1980s



Thanks a lot

Looks like an Elson tank too me aswell. Stupid overcomplicated things!

Thanks guys

Do you know much about these? I have 2 overflow pipes coming out of it and it seems that the hot water one has a very slow overflow. I hear a slow drip coming from inside it.

I dont know how it all works inside, but I had the cold water stopcock replaced which is apparently fine (and no overflow occurs through the cold water overflow)

I assume theres another stopcock on the hot side? But is this fed by fresh water directly, or through from the cold water side?

Sorry for my lack of knowledge

Thanks alot

I can't actually remember how they work as all I've ever done is rip them out. Slow dripping sound will probably be caused by a worn ballvalve. Easy to replace, in theory. But judging from your pic you don't have much room above it to work!

I can't see your piccies but if it is an Elson you could well find two ball valves in it.
One for the main storage and one for the central heating f&e tank.

It's basically a cylinder with a built in feed and expansion tank above it in one unit.It will be the ball valve that needs changing.

To give you a idea of how they they work

its a direct so should only be 1 overflow. dripping sound is probably the ballcock.

Where is the 2nd overflow?

If its anything like most of the ones I've been to it'll be fitted within 2 inches of ceiling and take 2 hours to change ball valve. Awful things.

Drain off , cut all the connections as close to floor as possible say 40mm, lift the front edge up slide some 2" x " under
and it will all slide out, replace the ball-tap make sure you adjust it right height slide it back in and use a compression
fitting on the hot and cold going down, BTW when you cut the pipe off they might drop through the holes so wedge the hole, no fool like and old fool, good luck
