Mikew Posted January 18, 2005 Share Posted January 18, 2005 We live in a six year old French built 'pavillion' house. The drainage system seems to run slowly at times, noticed because the toilet bowls do not empty as speedily as expected. The pipe system is visible, suspended from the sous-sol ceiling, and appears very neatly executed. There appears to be no vent pipe to balance water/air pressures as in the UK. There is, however, a small valve about an inch and a bit in diameter which has a rubber diaphragm arranged to admit air only, but it appears too small to be of much use to stop our u-bends gurgling merrily (and ponging)when the toilets are flushed.The problem does not happen at all times, we are on mains drainage and I don't think there is an obstruction because of the intermittant nature of events.Is this normal French design, or should there be an equivalent of the stack pipe?Comments please.

Jeremy Posted January 19, 2005 Share Posted January 19, 2005 Well what a surprise.French plumbing being a problem...To stop your Gurgling you will need to somehow retro fit a soil vent system of some type.There are many. A GOOD plumber will be able to sort it and if it is internal can fit a balanced flue type vent which can be boxed in ( to hide it) and wont allow smells back in the house...Good luck.Jeremy Link to comment Share on other sites More sharing options...
