Toilet horizontal soil pan connector with multiple bends

[adamlondon]

Hi all,

I need some advice installing a new toilet. Please tell me if you think if it is likely to create blockage if I install an horizontal rigid pan connector with multiple bends; it is about 1.5 meters long from the toilet to the vertical pipe, and I have limited gradient (maybe 15mm if I am lucky) see drawing below.
I had bad experiences with flexible pan connectors before so I would prefer to avoid these.

Many thanks

Adam

oh dear, can the part in the floor be turned at all? or is it fixed in place?

Turn the pan through 45 degrees?

Is it on an outside wall

 

[PlumbBobBob]

looking at the position of the floor soil pipe i'd say a low level had been changed to a close coupled

The parts in black on the drawing cannot be moved, and modifying the position of the pan would be a last resort for all sorts of reasons.
It is not on an outside wall, the whole thing is inside the bathroom; the wall behind the pan is relatively small (bricks) but there is my kitchen behind so i cannot put the connector through there. I will have to box the connector somehow.

So do you guys think this design is likely to have blockages or will it work like this?

 

[Riley]

I personally don't think you got enough drop

 

[ShaunCorbs]

will block for sure could you get a connection lower than the existing one ?

 

[Riley]

What happened to the old toilet as I can't believe that set up would've worked for that either

 

[rpm]

Don`t know the fall on the pipe required with all those bends but raise the pan with a plinth and put a roding eye on the first 90?

 

[Riley]

Or a saniflow????????

Seen it done and the soil pipe was 18" away in a straight line!

Hi Steveb,

I think you are right the bathroom must have been designed with a low level toilet originally, and it has changed position several times over the past 30 years. Now I am putting a more modern one, and as you said the position of the soil pipes makes things a bit harder when changing the position of the pan again.

Hi Riley,

the old toilet used to face the soil pipe directly, so there were no bends and not much distance from the pan. Now the bathtub took the place the toilet (I am reorganising the entire bathroom), so the actual position of the pan makes the most sense.

The saniflow idea should work but that's another can of worms and expenses I would prefer to avoid if possible.

Good man!

I think rpm option is the best by turning at 45° if that's doable you can get some nice Corner toilets

Sorry Adam I actually meant 90 degrees, compass was out but 45 is a start. lol

 

[ShaunCorbs]

or can you do this?

Can you not cut the soil pipe below the branch & then you can put a new branch in at any angle....

Guessing it`s a concrete floor, still doable but ......

 

[clarky101]

Plastic or cast, wood floor or concrete....

Still doable, Is that your point mate?

 

[clarky101]

Point is the guy hasn't said so yes still do able....ok...

I get the feeling I`ve pee`d you off somehow, this was never my intention.... ok?

 

[clarky101]

Not at all matey, all good .....ok....

Any chance of cutting pipe flush with floor and using a Mcalpine DC1 fittings which fits inside pipe and and then a branch in to that? You'll be 120mm off the floor so roughly 60mm and you can go direct to pan and a 90 pan con

I unfortunately cannot modify the vertical soil pipe, its shared with the upstairs neighbour, and it is made of metal or ceramics I believe, so I cannot modify that part. The floor is concrete.

If I raise the toilet pan somehow, how much gradient should I have at least with all these bends?

Thanks

Adam

Adam you are misunderstanding I think. you should be able to cut the part fixed in the floor flush with the floor and do as several members have mentioned above. if you can post pics it would be a great help.

 

[JCplumb]

If you're ground level or first floor, is the loo backing onto an exterior wall?
If so, is there an exterior soil you can tap into?

 

[adamlondon]

Modifying the vertical soil pipe is not an option, and using a different one (or new one) inside or outside the building is not an option either.

If I raise the toilet pan around 8 cm, would that be enough with all the bends?

Thanks

Adam
