Truma leaking hot water overflowing

[Gunn Manor]

thanks Lenny HB ordered one, hope arrives by tuesday.
i refitted the existing one, all seals looked ok, couldnt see the valve which is probably the problem, and still getting small leak.

i ordered one of the above joints, its a little different from the original, has a larger joint for the metal pipe out of the boiler, just make sure it is seated properly and super tight. i used a fuel pipe clamp rather than the existing one, this has given a better seal on the hot water flexible pipe. refilled and hot water an heating on and being tested, so far so good.... fingers crossed this solves the problem.
thanks for the info.

Just adding to this Truma boiler water leak.

Using the Motorhome over the weekend, we have what I think is a slightly different issue.

When the hot water is on, approximately every 5 minutes I can hear what sounds like a dump valve and this spews a little water out of a pipe under the van.

The hot water is all working fine apart from this.

Ideas please?

Sounds like a pressure vent releasing,

The pressure release on Truma systems is the frost valve.

If you pressurised your system when cold it will expand and make the frost/pressure valve release some pressure. Obviously these valves can get some debris in them but if yours is sealing in between releases, it sounds ok. Running the hot tap once water is up to temp should stop the release valve operating

Thanks Andy / 1967bowesj, much appreciated.
I’ll give that a try when I’m out with the Motorhome next.
