Thread: Close Coupled Suite with large set out?

G'day, we're replacing a toilet suite in a late 60's house in Sydney. It currently has a ~6"(??) cast iron waste with a 230 mm set out. Firstly, does anyone know of any close coupled/BTW style suites that can handle such a large (S trap) set out? Obviously that's a more contemporary and cleaner look, but from what I've ben able to find it looks like a connector style only would be available with that set out. The floor has not yet been retiled, so it's certainly possible to replace the cast iron with PVC by punching up through the floor at lesser set out and plumbing that into the gully, but that changes the job from 1 hour to 1 day (at least)!! ie PIA factor is big.

HOWEVER part 2 of the question relates to plumbing into that cast iron using a pan collar. The current trap is exposed and mortared into the cast iron, easy-peasy if we wanted to replace with a retro style pan. I'm just not sure how to tackle a skirted pan and wondered what adaptors are available for the cast iron where I also won't have access to the trap outlet when bedding the pan?

Hopefully that's all clear, and thanks in anticipation.

Edit: On further thought, would it be possible to cut the soil pipe flush with the existing floor and use an offset pan collar to bring it back toward the wall? It would need to go back around 80 mm. Just not sure how to couple the pan collar to the cast iron???

Photo would be handy, it's probably 4" though.

Good idea, hopefully these post ok

Definitely 4" waste, you'd be best off with a BTW suite. You'll have to shop around to find one to suit that particular set out. Being cast iron I''m assuming you have access under the floor? At worst you could move the waste.

4" yeah ok that would make sense. I haven't been able to find any BTW suites with that 230 mm set out. You can see how tight that toilet is, so anything to give more cat swinging room I'm sure would be a good thing!!

Yes as mentioned I could move the waste as the under floor access is pretty good, and it will (eventually) be retiled (the toilet will be lifted again for retiling BTW), however I'd prefer not to have to move the waste if I can avoid it. That's what got me thinking about an offset pan collar to move the waste back toward the wall, but I don't know whether it would all fit ... and my gut feeling is it wouldn't, not to move it that way, coming away from a wall is a different matter. Putting a new waste in would of course solve all these problems and I'd be using conventional contemporary fittings, BUT as mentioned it turns it into a pretty big job.

Not as hard as you think mate. Wait until you're ready to retile and do it all in one hit.

Agree. If you can get under the house easily its a piece of piss ( pardon the pun)

No the suite is going in now, and the tiling will be done later. The initial intention was that this would be a "quick" job to get a new suite in. So much for that idea! However nothing much has changed and yes I agree, at this stage I think the best thing will be to move the waste. Indeed a new BTW should even cover the patch in the floor, so tiling later is no biggie (other than having to continue looking at awful tiles in the meanwhile I guess).

Pete

Well just make sure the floor is really flat, you'll need to silicone the new pan in so you can remove it later and if you have to make up a large gap between floor and foot of pan it doesn't work.
In saying this you will thank yourself if you wait until you renovate the room.

Thanks, I won't know what bedding I'll use until I decide on the suite.

Pete

Bare in mind if you have to chase any sort of gap larger than 10mm, sand and cement is the go.

Any tips in a situation like this where I know the pan will definitely be re-lifted off the mortar bed and it obviously needs to come off without any damage?

Pete

If you bed it with sand and cement, expect it to break when you go to remove it.
