Hello folks. So our mains water supply pipe got severed (not by me) and temporarily replaced so working fine but lying on the surface. Now have the new trench dug and new MDPE supply pipe and correct fittings all ready to go.
I've been out to the street (new-ish square plastic box with meter in and isolation valve-type stopcock) and shut off the mains supply (meter stops). Then I've gone in and run the kitchen tap to double check and weird stuff happens. The flow slowed right down to a trickle, then started to run again!
The property has an accumulator which stores 100l of mains-pressure cold water. Is it possible that, having shut off the mains supply, water is flowing back out of the accumulator through the kitchen tap?? (it's hard to trace, but I would have thought the accumulator would only feed the bathrooms, and there should be a non-return on its inlet??).
All input gratefully received!
