We bought this house last year. The old boy who owned it before died about three years earlier, and about the only thing he had done to the house in his two year ownership was to convert an attached woodshed into a shower room, with a Mira Sport 9.0 KkW eletric shower. This has worked absolutely fine until last Tuesday.....
Last October we had a new combi-boiler installed, and the loft tank & hot water tank were removed, so everything now runs off mains pressure.
The gas board surveyor wasn't sure we could have a combi-boiler, but when he checked the water-pressure, he said he had never seen any so high. I *think* he said it was about 6 bar.
Well... Tuesday night I had just finished my shower, and was in the next room hangin out my towell when the lights went out, and I could hear rushing water ! Having found a torch, and my way to the fusebox, I isolated the shower room, and then went in and isolated the water flow. [OK, you can stop laughing now]
So I have dismantled the shower unit, and the plastic moulding has split right across, with a rubber gasket thingey sticking out.
Mira say that all their units can cope with 5 bar "maintained" pressure (I *think* they mean "dynamic" pressure) and can cope with up to 10 bar static pressure. So I guess that means that NONE of their units can cope with our pressure.
I can get repacement parts for about £60 from them, or a new updated version for £187 - but the impressionis that it still would not cope - the old one lasted for a year, though, so I could take a chance. Would restricting the flow help ?
So either I have to fit a pressure-reducer, or buy a different make that CAN cope - but catalogues are usually vague re pressure !
I suppose the first step should be to go out & buy a pressure meter - I see I can get one for £8 at

But how do I use that to measure the "maintained" pressure ?
Suggestions, please ? (Preferably clean ! I wish I was !)
