Toilet Waste Pipe

Doolittle51

I replaced a toilet recently but the waste connection is causing problems. First I tried a standard right angle connector, which was how the old toilet was connected, but I have raised the height of the floor by about an inch so it didn't fit properly.

Next I tried a 'pro-plumb' flexible right angle connector, which required cutting a few inches off the soil pipe. It fit perfectly and all looked ok until I spotted a leak at the toilet outlet. Seems like a common problem with cheap toilet pan connectors, so I ordered a McAlpine flexible right angle connector online. A Muiltkwick one was delivered instead, but I didnt mind as it's still a reputable brand.

Anyway, I fitted the multikwick connector, but again, another leak! This time it's from a different place, as shown by the red arrow in the picture. There is a joint at this point, I think it's there to allow the connector to rotate if necessary.

Anyway it's driving me nuts. I'm planning to box in the waste pipe and tile around it, so I need to make sure there are definitely no leaks before I do this.

Are there any other options? I also tried a fully flexible connection but there isn't enough space for it. I really don't want to remove the toilet again if possible. Getting the pan connector into the soil pipe is a really awkward & horrible job due to the tight space etc. I'd appreciate any comments and suggestions!

A multiwick going into another multiwick is not recommended, extend the 4" sewer pipe using a 4" socket and push the 90 degree elbow into the 4" pipe instead.

It's only one multikwik. A right angle flexible one.

If I extend the soil pipe, it won't line up properly with a 90 degree pan connector. That's the way it was originally plumbed, but the floor height has been raised by an inch so it won't line up properly now.

Apologies, it looked like 2 seperate multiwicks, you could get a 15 degree elbow, that should line up with a 90 degree elbow from the back of the WC

yea, that might work. I've seen an adjustable bend online too.

Is this the fitting you have installed?

If so the fitting must be faulty if it is leaking where you say. I suspect it is actually two fittings and the toilet connector is not designed to go into the multiquick flexi bit into a solid waste pipe. Also I can see problems with a blockage eventually from the way the fitting is installed. Run a level from the left hand side (second metal band) to the bottom of the toilet waste ... that area is going to hold waste as it will never go up hill. As said, you need a decent short bend to take the solid wall waste pipe close to the pan and use a simple pan to waste pipe fitting.It can be done properly as there are loads of fittings. Your choice but I know I would not try to bridge that length of gap with a flexi fitting and then box it in.

Yea thats the one freddy. I think I'll try to extend the soil pipe and just use a normal 90 degree connector.

Hi
Would agree. Use 15deg wavin bend on existing pipe, a 90deg multiwick bend to toilet and piece 4" sewer to connect both. Flexible bends with creases in it could clog up, use std 15deg bend which is completely smooth inside.

Any idea where to get 15deg bends? I need a double socket solvent weld one if they exist? Can't find them anywhere online.

Hi
You don't need a solvent fitting. Go to any builders providers and ask them for a 100mm 15deg single collar bend. and also get a 100mm standard coupler,
(Checked wavin catalogue to find 15deg bends are only single socket)

One end of bend has a rubber ring insert, get some washing up liquid and smear the rubber ring with it and it will slip on existing sewer in your picture. Then the collar goes on next, then your sewer pipe to the 90deg multiwick. When putting the piece of sewer bevel the ends of both sides, this helps to fitting to coupler, Also bevel the existing pipe makes it easier for fitting to go on
Job done

Sorted! I got a short 90deg multiwik to make things a bit easier. All ok so far, no drips. Fingers crossed all is ok before I box it in next week. Thanks for the advice folks.
