Leaking hot water cylinder

[Utilmap]

From the attached photo is it possible to see if the joint and fitting is likely to be repairable and if so how.

if is not leaking bad leave it alone if it is leaking its a new cylinder job

Is that the hot water outlet or the tapping into cylinder coil?

Its difficult to see If its the joint or the cylinder itself leaking! Depending on age of cylinder you maybe able to repair, but when the joint has been leaking for awhile it makes it difficult to undo the old connections without causing further damage!

I would leave it until after xmas if its not leaking badly, if the cylinder is old then maybe worth changing that at the same time!

Looks like the coil connection to me. ( back nut onto cylinder).difficult to repair, when you try to tighten the back nut it splits the already perished washer ( inside the cyl) and then you have a big leak!
Like above you have 3 options.
1 leave it alone, its a very small leak.
2 have a go at tightening with a high risk of making it worse.
3 replace the cylinder.

as its christmas I would go for option 1..........

I had this happen to me one Christmas I noticed it whilst grabbing my shoes out of the airing cupboard on my way out the door for some drinks with the lads. Had a bag of plaster in the garage, quickly knocked abit of that up and smoothed it all in there. Stopped the leak and when I sold the house was still holding back the leak.

WTF, new one on me!

Not the sort of job you would want to call to late in the day to do a "nip-up"
I'd only try anything on that cylinder if I had a spare day to allow for a drain down (or 2), then when I couldn't fix the leak, fit a new cylinder
Don't know how successful a repair you could do on that, maybe a home made PTFE washer and some on the thread
But, as said above, I think it would be a job for the new year if it's not leaking too badly

Ive heard of white gloss paint being used as a thread sealant, but never plaster! Must let the buyers know...

i had that exact leak on a cylinder not too long ago, ended up changing the cylinder in the end.

plaster used to be wound in with the hemp years before you and I were even thought of CHK

Leave alone until after new year - DO NOT TOUCH IT - all the below hints are ace
my suggestion is as it is a low pressure joint - diy shops sell a type of epoxy resin in two bits rub together and apply to the outside of this join - but dry it out first with paper napkins
BUT DO NOT MOVE IT OR BASH IT - then think about a new cylinder

about £150 + vat and you will get £30 at the scrappy for old one Centralheatking

That's it then.

binning the jet blue.
have got a bag of bonding and multi finish in the garage! :biggrinjester:

When I was an apprentice we replaced some 4 inch cast pipework at a stately home. The joints were make with hemp and neat cement.
