Toilet to cast iron.

[T i m]

Hi all,

We are currently looking at fitting the new WC round at Mums and from a preliminary look today, seem to have found a lead 'tube' that was set in some sort of white 'cement' and inside what looks like the connecting collar of a cast iron soil stack type connector.

The collar part is mostly proud of the wall (so you can see both 'rings' of the outside of the socket) and seems to be intact.

Now, if we cut the collar part off (angle grinder / hacksaw) we would be more flush with the wall and presumably of a smaller (neater?) diameter so could we then more easily find one of the push in connector / couplers to do the job do you think please?

Cheers, T i m

The wall thickness of cast iron pipe is lots more than uPVC also the inside is quite rough so leaks are hard to avoid with the "multiwick" thing.

The traditional way to do it is with putty and paint. All surfaces are painted and the joint is made with putty. The surface of the putty is also painted. The "white cement" isputty gone hard. The paint aids adhesion and helps prevent the putty from going hard. (But it does anyway) Any movement was taken up by the lead pipe.

If you can find one that fits, you might try a connector with a load of silicon jollop on it inside the CI pipe. The pukka way is to renew the pipe in the wall thickness from the joint outside. (using jollop/siliicon once again). Quite hard to open a CI joint without damage. (depending on the joint material which could be cement. putty lead etc.)

Once the old bog is out of the way, I'd be tempted to fit a short piece of upvc pipe into the the remains of the CI spigot (trimming if you wish but dont crack it!) with putty/ silicone/ plumbers stopping etc. Then you have a good surface for a multiqwick fitting to seal against.

Is that the 'Plumbers Mait' stuff?

Understood.

Ok.

Didn't know that but it sorta makes sense.

Yup. ;-)

Ah, clever. ;-) [1]

Hmm.

I'd have to say I'd rather avoid that as it's just above the lightweight leanto roof. ;-(

Quite.

Ok, well thanks for the feeback, interesting.

p.s. I was watching some Youtube vids about doing such jobs and they were using 'Ochre' to act as a pre wad before pouring lead? These were mainly on the vertically connected WC's though.

[1] When I fitted our WC over 25 years ago I set it on a cast-in-place cement plinth with (from memory) a fine skin of silicone to 'stick' it in place. So, in all those years there hasn't been any 'movement' and that's even with it being stood on etc. I'm not surprised such leaks do happen though when you see how 'loosely' some WC's seem to be fitted?

Do they actually make an 'official' component to do this sort of thing though please? I'm not suggesting I would use one versus something more 'imaginative / practical', just wondering?

I would have left the lead_lined_cemented_hole in place and seen if we could adjust the height of the new bog to suit but there was a hole in the cement at the top so we started to clean it all out.
