Immersion tank apartment leaking - lockdown

[boxrick]

Yesterday we noticed our immersion heater tank leaking. It’s quite bad and pooling up over the course of a few hours.

Anything I can do to resolve this? I’m worried that plumbers won’t be working right now due to the virus.

Some plumbers are still working. If you haven’t been tested positive or have no symptoms of Coronavirus, then should be ok. You just need a G3 registered one, as that’s an unvented cylinder. Where’s it leaking from, couldn’t see in those photos?

 

[boxrick]

It’s hard to tell, but looks like it’s leaking from the bottom, all the valves are dry.

Check that plastic pipework, and the prv/tundish (Circled on photo).

Cheers for the replies

Think it may be this seal in what looks like the overflow.

I guess this may be a Screwfix job.

There shouldn't be any water in those pipes so you still need it looked at.

@picasso beat me to it, and agree, there shouldn’t be water in that pipe, unless there’s a problem. Not an overflow really, so yes, get it looked at.

Yea its still coming from bottom of the tank. I guess I can probably drain it to stop the leak for now?

Turn the water off and see if it stops. If the Pressure Relief is letting water out then there is an issue with the tank and as said, you will need a Plumber with a G3 certificate to look at it.

Thanks for the help everyone! Got a specialist coming out on Monday. Just will have to hang on till then!

 

[Hugh Jaleak]

If it's leaking out the joint where the copper pipe meets the plastic, then nothing stopping you trying to seal that up to stop any further water leaking into the property, but the cause of that overflow will need to be professionally checked and remedied.

So I have had a professional look at this a few times:

1st visit) He serviced it, repressurised and examined some bits and said it was absolutely not the tank leaking, after a short period it was still leaking from the back of the tundish.
2nd visit) I let him know it was still leaking and asked him to replace any bits which were likely to cause me issues, so this was the large cylinder at the top and the valve circled on the left of the tank. He also re-plumbed a loose connection at the bottom below the tundish at my request
3rd visit) Now the 'leak' had been fixed since the tundish was a little loose, however there is still a low infrequent drip from tundish randomly. So he replaced the valve on the right hand middle of this picture also circled.

Now it is still dripping inside the tundish and we have replaced most bits of this system... except one valve at the back. Does anyone have any ideas what this could be? I am a bit lost and am £250 down.

I cant see any cold water take offs after the pressure reducing valve so you might have an unbalanced supply problem, usually a shower or mixer tap passing high pressure water back to the cylinder.

I can’t believe you’ve got all that water above and next to a consumer unit

It's not the best place for the modem/router either.
