    Does anyone know why after 12 years of living in the same house here in France would the water pressure suddenly shoot up from the normal bar of 3-5 to off the dial resulting in water shooting out of our hot water tank at a great speed of knots.  Called in our plumber who turned off the hot water on the tank so we at least had cold water.  He came today and fitted a water pressure regulator to cure the problem and he said he had never come across this before.  No work going on in our village affecting our water pressure.  Anyone got any clues? :unsure:

    Just wondering if you have a presure regulator between the counter and the hot water tank on the cold water infeed, which you may have inadvertently opened up to full  throttle. The reason I say this, is because we had a problem once which couldn’t be identified by the water board where the pressure to the tank and thus the outfeed pressure from the hot water tank, had dropped off considerably. The guys from the water board were actually leaving the house scratching their heads and getting in their van when I suddenly remembered that behind  the wall behind the TV, there was a plastic cut off tap which I had installed years previously and which several days previous to  the problem, I had closed off and then only opened a wee bit. I called the guys back in and told them  his. We then opened it up and that was the problem. A really evident remedy, which I should have remembered.  So, just wondering if you have the same problem in reverse?

    Thanks Gleaner.  We didn’t have a pressure regulator for the 12 years we’ve lived here but our plumber installed one for us yesterday.  It certainly is a mystery!

    As soon as I moved in I had a regulator fitted to reduce the pressure from 7 bar to 3.

    Our mobile home, connected to the same water supply as the house, had plastic fittings, I discovered one morning that during the night one of these fittings had blown off under the water pressure meaning we had full bore water pouring out for a few hours. Our plumber came and fitted a pressure reducer, telling us that very often water pressure can jump up lots of bars during the night.
