Unvented Cylinder - Tundish Leak

[Harvest Fields]

It is all built into the tank. It’s a Megaflo indirect cylinder.

There is one on my estate that needs doing every 6 months.

Why do some need this others don’t?

Air may be escaping from somewhere.

For the 3rd time in 18 months I have a small leak appearing on the ceiling under my unvented cylinder.

Last time this happened was in March and I was told this was as a result of the air gap needing replenishing which the plumber did for me at the time. It was previously done in November last year during the systems first service.

It is normal for the air gap to need replenishing every 4 or 5 months please?

If you are having to keep topping up the air gap, you could get your G3 qualified plumber to install an external suitable expansion vessel

I suggested that to the bloke around the corner to me but he wasn’t having it

Some people just won’t listen.
Should then have told him, - all he can do is pay for install of a brand new replacement Megaflo.
