Hi guys,

Just after some advice if possible please?

We just had a new hot water cylinder installed and have noticed it dripping from two places.

Below picture shows the drainage overflow pipe which i understand is normal to drip:


But it is dripping far more from this pipe too:


I rung the original installer and he said it was normal to drip from both locations, but i'm a little sceptical about this so just wanted to double check.

Cheers

My plumber just phoned me to explain this in a bit more detail.

Apparently unlike Australia, the New Zealand building code says that all hot water cylinders need a special valve, before the overflow pipe. SO in Australia, they only rely on the overflow pipe but here, they need that extra protection, so the overflow pipe itself will rarely drip - instead, it will come from the other pipe in the first instance - if that makes sense?

it doesn't matter if you are in the US, australia or the north pole. there must be no drips from the piping at a water heater.
call the plumber back to fix them..

I believe that if you turn the blue knob near the leak in the last photo the water will stop dripping.
