Any Plumbers here?

[Maurice Swan]

The drain valve on my hot water tank is dripping from the outlet (controlled by the red switch)....
The whole thing is only about 2.5 years old so want to avoid calling a plumber if possible.

It may be that even over this timescale, some calcium is stopping the red switch from fully closing. I have tried the anti calcium formula sprays to no avail Is there a simple solution to stopping the drip?

Fair play Mo, we have on here
Climate experts
Plane crash experts
Fiscal experts
Covid experts
Virology experts
experts for everything depending on what is topical, unfortunately
no plumbing experts!!!.
Other than gas i do my own plumbing
Hot water tank ?, it's all condensation boilers nowadays in blighty except for the climate nutters.

Is that valve a Caleffi 526 model ?

If it is, I'd have a scan on line for the Operation and instruction manual, the manual on the site linked only has the installation instructions, the OIM should give a parts breakdown & assembly instructions from your picture I'm presuming that it's leaking through the valve and not where the grey elbow is screwed on ?

Mo, the valve isn't fully closing, same thing happens with isolation valves. Get a new one, once they're ****ed it's difficult to repair them.

Certainly looks like it....I'll also have a search tomorrow.

Correct......just seems like the red switch needs cleaning so it closes properly.

@Tuerto
Things is that it's not even so much the cost of the part.....it's the cost of fitting it...not confident I can do that myself.
