Just iftting a new bathroom,,the new ones arent as good as the older stuff are they and neither are the fittings!!. I note the bath waste is made of plastic and instead of the old style threaded flange with back nut,this is a two piece plastic thing with rubber seals and the only thing holding it together is a machine screw down the centre of the waste from inside the bath which engages with a brass insert which is fixed in the lower half of the plastic waste..it doesnt look very solid,do they ever fail/flood the place?
Also,given that washers are supplied,is it still a good idea to use silicone sealant on the washers/flanges?
