Hot water heater leaking. Repair or replace?

[Colin Mowbray]

Hi, I've got a brand new (2nd hand) Bosch Hydropower 16H tankless hot water heater. Since it was installed I have noticed it leaks a lot. I took the cover off and it looks like the bottom part (water section?) is leaking in a couple of places. maybe a seal or diaphragm? Can it be repaired or should I start again? I don't have a warranty as it was second hand, but it was brand new and unused.

Turn the water off and take that union nut off and make sure it has a gasket in it if it takes one. Also make sure the plastic
piece that the nut tightens too isn't cracked.

Thanks but they just referred me to a plumber.

Thanks, good idea. I'll check it out.
