Triton T100si electric

You will have to check and see if it is the outlet pipe thatis leaking or the pressure relief device that has activated.

If it is the outlet pipe then you probably only need a newhose

I think the pressure relief device has blown.

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

It is fairly easy to replace however there isusually something that causes it to blow,

often a kink in the hose or the showerhead isblocked, so check this before fitting the new PRD.

I think that one of the relays on the PCB is stuck in the on position and this is keeping the solenoid valve energised after you have switched of the shower.

I think that you are going to need a new power PCB

Unfortunatelythere is nothing that is a direct swap.

However.......Triton has recently brought out the T80Z this shower has been designed roundbeing a retrofit unit  (Tritons word notmine!)

Thepipe work can be brought in from almost any position and there is a reasonableamount of space for cable entry from most positions.
