Hi all.
I am becoming increasingly confused as to where a Durgo can/can't be used.
My bathroom has a 110mm soil pipe running down through the roof, loft, bathroom, cupboard downstairs and into a clay drain in the concrete floor of said cupboard. It then runs out below the front of the house for about 8 feet, into a rectangular chamber with a cast iron lid, where it joins the drains from the "upstream" houses.
We want to liberate some bathroom wall and corner space, but going outside with the vent section could be problematic. Marley's 82mm Durgo says it can be placed lower than the110mm version.
Some people say not to use a valve unless there is a proper vent somewhere else on the system, but they are clearly being sold as an alternative to venting. (e.g. Wickes leaflet 73).
My bathroom set up looks like this apart from the fact the svp continues through my roof and the basin waste follows the red line. Can I / should I use a Durgo valve here, and if so does anybody know what the lower height would be for an 82mm version? And why the different heights?
Any definitive expert help would be greatly appreciated, as there seem to be plenty of conflicting opinions about these devices. Thanks in advance.View media item 22180
