Long shot, but does anyone know what happened to the manufacturer 'Main'? I have an old Main Nymph water heater fitted in a 1978 caravan, but they were also fitted in portacabins, narrowboats etc. I need a new water flow sensor diaphragm for it.
Anyone help me out?
Steve
Baxi Potterton now own Main, and still make a couple of the models. You could try HRPC for spares. Yours sounds like a specialised version, but if you're lucky, it will have the same flow valve as some of the other more common models.
great thanks, I have emailed them, hopefully they will be able to help!
Steve
nope, said part was obsolete. bugger, now I have to fix it meself
Steve
Nope, the heater is obsolete you need to replace it?
Why replace a perfectly good heater? other than the diapram, theres nothing wrong with it. i am now fixing a repair so that it will work. the worst thing that could happen is that it wont work! the diaphramg is part of a water flow sensor, so not part of any gas fitting, so no danger involved.

No the worst thing that could happen is that the gas valve sticks on and the water heater boils. See the humour section in the main FAQ.
No, the worst thing that could happen is that a H bomb is dropped on my house. This old, but sensibly designed water heater has a fail-safe design. No water flow, no gas flow. (however, the spring in the gas valve may fail, in which case the failsafe system wont work-but this could just as likely happen in a new gas water heater.)
Steve
Newer gas water heaters have an additional safety cutoff.
