Cast Iron Soil Stack - Toilet Move!

[aia0202]

Hello All,

I am about to start installing a bathroom. Only sensible place to put the toilet is in the worst place for joining to the soil stack.

Easiest way to see this is with a photo. Red circle shows where the new soil pipe would ideally come out of the wall. Would be good to have people's opinions on how best to tackle this.

I would like to try and avoid running a soil pipe on the inside if possible but if not is there a way to box the soil pipe in to conceal it?

Thanks in advance,
Andy

Stick a 90 degree pan connector on it and take it to existing stack entrance.
Probably easier with a pic.

The green bit is the internal soil.
Decent drop on it, but it will need to be concealed with boxing or bathroom furniture. Shouldn't be too much of a problem though.

Personally I'd install a new plastic stack outside, kicked over to the left and the waste pipes bossed in so you can get rid of that old rainwater hopper.

Oh and make sure you have a well placed rodding point cos if this ever blocks it will be at the right most part. (as you look at the pic)

Or do what TB said

That would be my concern.

take it the existing wc is going. cut stack below branch and replace with plastic all the way up. put branch into wall with a 135 on it to get it in the correct place

Replace the whole thing and run it directly into the new stack. Much rider than you have now and you can clean up the hopper as TB pointed out.

Thanks for the fast replies everyone. Have read elsewhere that it can be difficult replacing the whole stack so wanted to avoid. Seems like it might be the best way though.

Any tips on the best way to cut and join to the iron pipe at the bottom, or is is best to dig out the lot?

Plus one.

Look and last a lot longer . Or shake stack until joints loose and work back to last complete joint. Installing a nice new plastic one from there. Sending floaters left then right then left again is a recipe for disaster.

Thanks again for the replies everyone, posted last night but message hasn't been moderated yet.

Whats the the deal with having the rainwater and guttering straight into the soil pipe? Is this not the way it is now?

If it's existing you can keep a combined system.

Rainwater goes to soakaways now, well for at least the last 40 years.

Rainwater into Foul can cause overloading of the Foul sewers.
