Internal leak near top of unit. Only starts leaking when shower is being used

I couldn’t really tell exactly what is leaking, could it be the on/off switching unit? The shower in less than 3 years old.

I would usually say , I think the Pressure Relief Device (PRD) may have activated.

It’s a safety device on the bottom of the heating tank.

It is fairly easy to replace however there is usually something that causes it to activate, often a kink in the hose or the shower head is blocked, so check this before fitting the new PRD.



But if the leak is at the top this cannot be the case.
There maybe water spraying from a joint or at the union between the inlet connection and the shower.

You will need to find the source before a part can be replaced.

The hose has never been kinked and the shower head isn’t blocked. If the pressure relief device is on the bottom of the heating tank it definitely isn’t that because the leak is coming from higher up to the left of the heating tank.

Yes it could be the on / off switching unit, but you really need to be sure before ordering parts.

Switch off the power, carefully dry out all the internal components fit cover turn on for 10secs. see if you can spot where the leak is coming from repeat until you have pined it down.
