Bath overflow leaking like Niagara

[dilalio]

It does now funny, though it's 25 years old, the new one looks to be the same part...

I take it they're both mcalpine? Good sign of a decent manufacturer... Its the same as one I did in the week.

I don't think so actually... it's this one, which is unbranded.

And I was just about to fit it, when I noticed this:

Doesn't look great, does it... back to SF tomorrow methinks

No the only McAlpine one they have is with a manual plug... probably should have gone for that...

Well, got it changed and... it nearly works!!!

Actually, it VERY nearly works. The bit I expected to leak (the waste) appears to be compleely wateright... so far... but there's a slight weep from where the original problem was, ie through the top of the overflow.

I cleaned the surfaces and assembled it all very carefully, and there's not much to go wrong really... just a big rubber seal against the back of the tub. I *hate* using silicone on something which should work without it, but maybe it's time for a quick dab...?

Is the rubber seal centred properly over the hole in the bath ? Is it fitted the correct way up ,some are not flat washers ? I have never had to use silicone or anything else to seal the overflow assembly to the bath ,other than the supplied seal.

Well, I think so... it's one of these, if that helps:

Is it fitted the correct way up ,some are not flat washers?

Again, I *think* it's flat... but look what it has to seal against

Well no wonder it leaks !! That area should have been smoothed off by manufacturer. Out of curiosity ,on the underside of the waste hole in the bath ,is that area smoothed off ?
Unless you apply silicone ,or mait ,its unlikely that you will seal that overflow with just the washer.

Really! I of course had no idea… guess silicone it is, then…

I’ll go and look when I get a minute. But it has sealed so far – I filled the bath to overflowing (to check the overflow, of course) & emptied it all again, with no drips from underneath.

At least I’m doing this on a concrete floor, not a wooden one
