westland Posted August 9, 2007 Share Posted August 9, 2007 As part of our small extension we have a new chauffe eau which seems to have been working fine for a couple of months. Recently the water pipes started to buzz almost constantly and after a bit of reseach on this forum we checked the security valve on the chauffe eau and found that it drips all the time. We phoned the plumber who said that he doesn't know what is causing the noise in the pipes, we asked re. a pressure reducer and he agreed that this might solve the chauffe eau drip - we are hoping that it might also stop the pipes buzzing.However, as we are still having problems getting him back. I am wondering how easy/difficult it might be to fit one myself? OK don't all laugh at once, what do you think? P.S. He did also say that the water company might have turned up the pressure, does this sound plausible? Link to comment Share on other sites More sharing options...
Gluestick Posted August 9, 2007 Share Posted August 9, 2007 Mine, (four years old, 200L from Leroy Merlin) has the same problem.Personally, I would change the Groupe De Sécurité : given reasonable pressure norms, it still should not leak!If not too old, call the installer/supplier back as it will be under warranty.

Anton Redman Posted August 9, 2007 Share Posted August 9, 2007 As above I would try the GdS first but assuming the feed into the CdE is on flexiable you may be able to install a 20/27 ( AKA 3/4 Inch for those who do not think Napoleoin won) reducteur de pression with M ( Male) on one side and F(Female) on the other just by undoing the feed into the fleixable pipe to the cylinder, after having turned off at the mains. Depends on clearences and will not work if the pulmber has used copper all the way to the cylinder.One down side is that if you have a thermostatic mixed valve for a shower then you should also limit the pressure on the cold feed as well. Ideally by putting the valve before the cold feed tothe rooms which use the CdE. I would not expect a GdS to start leaking in less than six months.

westland Posted August 9, 2007 Author Share Posted August 9, 2007 Thanks for the replies.. The plumber was suggesting that he puts the pressure reducer just after the stop tap where the supply enters the house, so hopefully this would mean that the shower mixer will be OK. However, reading your replies it looks as if the problem is more about the GdS. Chauffe eau and all plumbing was installed in Feb this year, so if/when we get the plumber back we can question whether we really do need a reducer. The pipework is all copper so think that we will have to reply on him. Link to comment Share on other sites More sharing options...
Anton Redman Posted August 9, 2007 Share Posted August 9, 2007 Suggest rely not reply on him. It is will be a very quick job for him ( Assuming his/her plumbing is not being realigned) to do it you are only talking 10 Euros in parts. Link to comment Share on other sites More sharing options...
Gluestick Posted August 10, 2007 Share Posted August 10, 2007 The Safety Valve should not leak!I really suggest that when you get the Plombiere back if the Ballon was only installed in February, then it needs a new valve.What happens if the pressure reducer is fitted: and the valve still leaks?

Nick Trollope Posted August 10, 2007 Share Posted August 10, 2007 Coupla small points;The GDS should drip - but not all the time. It will drip when the water gets hot and expands.A C-E should operate at about 3 bar. If your incoming mains is higher than this (quite possible), then you must fit a PR - in the incoming supply. This will probably stop the drips in a new GdS. Link to comment Share on other sites More sharing options...

westland Posted August 13, 2007 Author Share Posted August 13, 2007 An uptdate for anyone interested/having similar problems. The plumber has been today, tested the pressure which was at 7bar and fitted a pressure reducer. The buzzing pipes and chauffe eau drip have stopped. Didn't like to tell him that thanks to research on the forum we had an idea what the problems might be! Link to comment Share on other sites More sharing options...
