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?
I've just fitted something similar and note what you say about the new
style wastes not looking particularly substantial. I assembled mine
with a smear of silicone on all mating surfaces, tightened up the
screw down the middle tight enough so that any tighter I'd worry about
stripping the threads, and it's all okay so far.
Purists might advise against putting silicone on everything for good
measure but you can't see it and it can't do any harm, so if it gives
a bit of extra peace of mind then why not.
I would advise not boxing in the bath completely for a couple of weeks
afterwards so you can see if a leak develops. In my case I had no
leaks from this particular part of the plumbing, but did have a slow
leak from a compression joint, so it's worth keeping an eye on for a
it's imperative to use *plenty* of silicone when dressing the bath and sink.
I usually dress the bath and sink the night before I'm fitting it and leave it
overnight to set. usually works 1st time. usually.
