@McTag,
Oh no..... not sorted.... leaking loos!!!!!
Who knows when SWW will turn up - thing is... still can't quite understand it.... I mean, when I didn't have the water meter.... the pressure would have been around 7-8 bar.... and no loos leaked etc.... so even tho there is a PRV there on the water meter.... I get the logic of the pressure forcing the valve up and causing the loo to run constantly.... but if it didn't do it before the PRV at higher pressure, why would it do it now?????
mmmmm... confused! Wonder if both cisterns are now broken when the air lock blew.... shower head was blown right out!!!! Strange a?
Good luck with the electrician - do you have an RCB which is switching the power off each time... could be a faulty appliance as opposed to the circuit, depending on how sensitive the RCB is??? Hope it won't be expensive too for you.
