Helping a friend at a small house in France.
Please advise about this thing on the bottom of the electric hot water tank.
The cold water comes in from the right, and I presume the TOP half is a pressure reducer, for the water to then go upwards into the tank.
I also presume the BOTTOM half is a pressure safety valve, if and when the water in the tank expands.
(I am used to seeing an expansion tank attached at this point in the UK.)
Anyway, yesterday I turned the bottom tap a bit anti-clockwise as a routine test, BUT it will not go back again, and water continually flow down the overflow below. No doubt the limescale has got to the thing.
We then turned the water off entirely and headed to Blighty.
This WHOLE system will be replaced in the summer, but we would be willing to buy a replacement unit for the next few months. Or shall I take the plastic knob off and try using grips to turn clockwise?
Is there a French 'Plumbers-R-Us' that might STILL sell an exact replacement?
By the way, I assume the inlet pipe is 14mm, if you are able to judge it from the photo.
As Del Boy would say, "Mange tout, mange tout".
