Plastic pipes and stone walls

[thunderhorse]

I've just punched a hole through the exterior stone wall in preparation for a 100mm polyprop waste pipe. The pipe is tough and I can't see why it shouldn't be mortared in, but would it be advisable to somehow pad it and avoid contact with the stone/mortar (or even facilitate removal in case of a fault?)

Well I must admit I have never sleeved any soil pipes.........and I have installed a lot, never had any complaints about it either, in fact about the only thing I have ever sleeved has been copper gas and oil pipes.

If it were me I would put some form of lintel accross to protect it. You never know if you ever have to remove or replace it it would be a real pain if it is cemented in.

You can mortar it in without any concern.

Really depends on the make up of the wall but ideally you dont want anything bearing directly on the pipe so careful choice of location using a tie stone as a lintel may be an idea. Dont be tempted to squeeze pipe into a gap that is too tight its better to have a bit more mortar than a split pipe inside the wall.

I must admit......French soil pipe is an awful lot thinner walled than the English variety.

I must admit to putting my full 100 kg on it and couldn't even begin to deform it, but I don't suppose there's any harm in putting some form of bridge over through the wall.

How can you say that when dibble hasn't even told us how big his hole is?? [blink]

Because dear Katie its a failing of  blokes generally! French soil pipe is a more brittle type of plastic in my experience also it seems a lot less UV stable . If a pipe is surrounded by a good bed of mortar the some loads will have the opportunity to pass around it. A point loading from a slighly shifted stone could crack the pipe inside the wall. I didnt spend ten years of my life fitting bogs and not learning a bit about soil pipe..........Oh how I miss it............not!

be nice and annoying if you have to remove it ive sleeved all my 100 mm pipes by cementing a 125 in first if i need to change my soil pipe it will be an easy job

I used UK 110mm pipe as a sleeve on 100mm French pipe where it passed through a flint wall - perfect fit allowing movement/removal but not insect or rodent access. It was just lucky that I'd kept that short length of 110mm pipe from when whe had our UK house extended in 1990. I knew it would come in useful one day.

Alane,

I sincerely trust the membership of this forum will permit my rather presumptious move by awarding you a top 20 place in the Best Building Tips category.

I am intending to use a 109mm pipe and a tube of  KY jelly on mine !

[thunderhorse]

Thanks for responses. Plenty of ideas.

I take it you are now all bored of comparing your pipes. [:D]

Oh the wit [:$]
