Sorry for such a dopey question, but I'd like the technical term for it.
It's the bit that forms the plughole on the inner side of the bath, and a
short pipe on the underside, that connects to a wee u-bend type off to the
waste pipe. Mine's a bit loose and I'm not sure if it's easy to replacce
(doesn't look so) or if I can simply bung some sealer around it.
Is it the pipe that's loose? Check to see if it has a screw going through
the middle of the plughole. If so, try lifting the pipe up against the
underside of the plughole so it's tight, then screw in the screw until it's
How old is it?
If it is antique connected to lead then you may have problems.
If it is more modern it should be easy to take apart and re-assemble.
[If it is not leaking, just try tightening up the fixings and see if that is
Assuming it is modern:
You should be able to unscrew the trap and remove it.
[Something underneath e.g. a shallow tea tray to catch the water]
[Unless, of course, it sinks through a hole in the floorboards, in which
case reassure yourself that the small amount of water you spill will
probably not show through to the downstairs ceiling. Try stuffing an old
towel round it to soak up as much as possible.]
Fixing of the bath waste is generally either by
a plastic nut screwed up the threaded outside of the bath waste from
underneath the bath, which pulls the plug hole bit down into the bath
a screw through the centre of the plug hole bit which pulls the bath waste
up to the bottom of the bath.
You can therefore remove the waste, clean it up, apply loads of silicone
sealant to top and bottom of the opening in the bath, and refit the waste
and tighten everything up. Wipe the sealant from around the waste inside the
bath, but don't worry about the underneath ;-)
If it is a nut around the pipe, PTFE tape also helps to create a seal
between the nut and the pipe.
Refit the trap, fill the bath full of water, release plug and pray (after
obviously giving the silicone sealant the recommended time to 'go off').
I think the bit you're referring to is called a waste grate. That's the
chrome or brass finished bit the sits in the hole of the bath.
If it's really loose, and depending on which style it is, you may have to
put a thicker rubber washer around the under side of it, against the bottom
of the bath, and a squirt of gutter seal between the grate and the surface
of the bath.
There are two style used for the clamping fit. One style uses a bolt
screwed through the centre of the grate and into a threaded sleeve in the
body of the spigot. These are notorious for coming loose due to the
threaded sleeve pulling out and the only real way to repair them, is to put
a longer bolt with a nut and washer inside the spigot and re-tighten. Make
sure you get a brass bolt and nut, even if they are chromed, make sure they
are actually brass.
The other style is an actual one piece grate and threaded tail, which uses a
bit nut to clamp the whole to the bath. If these become loose, then it is
usually a case of squirting some sealant between all the surfaces and
tighten up the big nut.
