Advice for adding a branch into my existing stack

[J murton]

hello

Would like some advise on how to connect a new toilet to my existing stack.

I currently have one toilet upstairs but plan to run a new waste for a new downstairs toilet.

I know I have more than enough space to run the waste but my question is what is the easiest way to put a new branch connection into my current stack ?

Any recommendations would be helpful

Thanks.

Yes tee branch with the horizontal to a 90°through the wall. And sort out your outside tap that’s shocking

First thing you'll need to establish is where your current floor level is in relation to outside. What I would look at doing is removing the 2 67.5° bends at the base of the stack. Then depending on height of new toilet waste. Come up with a straight section of pipe. Tee accross for new toilet. Then 2 new bends on top of the tee to reattach the stack.

Haha it’s a new house for me so I have lots to do. The stupid hose tap will be gone soon though

This seems like a very good idea. I didn’t think of that. Thanks for your advice. I have a air gap beneath my house so plenty of room for the new stack to connect up.

Picture shows space. Probably about 1.5 meters from floor to ground.

I also have another question.
I’d like to change the stack because it’s a real eye sore.
Does the stack need to go as high as it does ? Or can I have it lower with an air valve instead ?

Why fix whats not broken, durgo or air admitance valves are an extra moving part which you do not need. Maybe you might want to go into the loft one day...who knows centralheatking
It looks like you are well in if thats a suspended floor air vent in the wall in one of the earlier piccys

Would leave as it if you want to smarten it up get some black paint and some new clips

 

[snowhead]

Paint it.
Don't use undercoat, just gloss, clean the green algae off first.

The 2 horizontal runs (from the bathroom?) could do with brackets and the rodding Tees are on the wrong way around.

Stack pie as per Craig, maybe with a rodding access just above the ground.

Great advice all round. Thank you

Can anyone clarify if push fit 110 is compatible with solvent weld 110 ?
Thanks

 

[ShaunCorbs]

Yes same pipe used for both

 

[Rob Foster]

Sometimes they are all compatable but this has always been my gripe about uk plumbing and heating fittings
not all are. It is totally stupid
but commercially sense to lock
end users into,this game.
basically dont buy any stuff from the big sheds visit your
local plumbers merchant buy their gear and it will all fit

I have found it depends on manufacturer.
