I have a job moving a toilet 90 degrees onto an adjacent wall. The toilet originally exited the house via a lead elbow into cast on the outside.
I need to extend the internal pipework approx 800mm, I have enough fall as the lead is low but the only connector I can find is like a pan connector and reduces the I.d. considerably and will cause standing water in the pipe. It also stands of the wall quite a bit and I would like to reduce this.
For numerous reasons I am trying to avoid ripping out the lead and coming off the cast outside with plastic.
Any suggestions?

Thanks end feed. I have that fitting already but It seems like the I.d. is greatly reduced. I will have to elbow off it and then another elbow approx 400mm away so the restriction and standing water is a concern. I'm off to the house in a bit so will get a pic of what I am trying to achieve.

ALL pan connectors reduce the dia, what ever make, what ever size, it does not cause problems

This is what I had done but wasn't happy with it or how big the boxing in would be.
Thankfully I have talked the customer into keeping the loo in the original place. Have to change the supply feed but on the plus side don't have to build boxing in.

It was the fact that the drain adaptor would have been creating a dam mid pipe and inbetween two bends. There would have been standing water in the pipe upto at least the elbow nearest the pan because there is only about 35mm fall over the whole length from pan to where it goes into the wall. With the bends as well it just seemed like a blockage waiting to happen. The other thing is that the boxing in would look gash. Customer agreed and I placed the toilet in both positions so they could choose. |

It's probably all too late for this.
I'm assuming that it's lead soil pipe up to that plastic connector (up to the new plaster)?
You can normally gain a bit of extra fall by chopping out the brick work underneath the lead soil pipe (into the cavity) then 9 times out of ten the lead pipe will bend downwards or even drop down by itself.
The old un's would have put a fall on that old lead soil pipe going through the wall by at least one course of bricks at the time of installation (it's what they did).
However, what's been decided is always the best and the golden rule in plumbing for all wastes is "Keep waste pipes as short as possible"!

Good tip about getting the extra fall. Thanks. I do try to keep wastes short and simple, would hate to have problems with anything I have installed as it makes you look a right cunt, not to mention the hassle of going back to sort it. |

Hi Dick. The lead is in good nick and reasonably round however it is cut flush with the wall. Could probably sink a fernco into the wall but the bend on the lead starts not far into the wall and I`m not too keen on having the joint in the wall. Good tip though and I will keep it in mind for the future. Cheers. I hadn`t considered it before because I thought it might crush the lead. |

Dollop dear boy, Lead Soil & Waste Pipes embedded in wall will be rotten, the lime rots the Lead. My advice is remove it all.

There is nothing wrong with the lead but ripping it out would likely end up in replacing a lot of cast iron as well which I don't have time for and the customer has already spent all their money on this house. its had a damp course, crack stitching and complete bathroom that they hadn`t expected or budgeted for as well as a full reskim. I just need to get it finished now. |

Lead normally stays in very good condition, although gas plumbers will tell you different and it all needs removing (because they don't know how to joint it anymore).
It was always on a bend on a hot water pipe or circ's bend where the old lead pipe would perish (due to years of expansion and contraction).
An old plumber I used to work with blamed it on the amount of dressing that the plumber did on it in making the bend during it's installation (too much initial dressing would have weakened the pipe he would say).
PS incoming main lead services also had a nasty habit of breaking off level with the concrete.

Lead is good for corrosion resistance, most things don't bother it and it forms it's own protective layer/passivation. I've never seen a rotten piece of lead, (but it can happen) only fatigued. |
