Cloakroom WC drainage plan

[swilli88]

Yes as you said i focussed on the distance i needed from the wall to best accommodate joining to the inspection chamber (which i havent yet done and today is a washout so will likely do midweek)

So i got through a barrel of work yesterday but finally managed to get concrete down. The fall I ended up with in the end was about 1:45 or 1:50 so happy with that and alos did the water leak test and not a drop lost over a full afternoon which was good enought for me. So i did the double layer of DPM, through in as much tec 7 as possible to stick to the old membrane (for what its worth) and got my rented concrete mixer up and running. About 200litres of concrete later attached is the result. that is a week of my life I am never getting back!

cant thank you enough @Hugh Jaleak for all your guidance over the last week. Been a really great resource for me that got me out of a few decision-making rabbit holes. You are very generous with your time and am really appreciative.

@Hugh Jaleak I have another one for you if youre willing

So when I put together that assembly behind the jacks I forgot to fit a small extension collar to bring it to the height of the toilet outlet

so now i have this

I meant to fit this but forgot...

beneath the branch connector behind the toilet seen here which would have raised it up enough

But now to fit one of those extension couplers is a bit of a pain in the hole to say the least, cause Iv already welded sink waste via strap on boss connector above it as you can see.

My options are

1) cut, repair collar, extender to bring branch up a bit

2) something like this

. My concern is the tortuous geomertry in this and that the majority of offset pan connectors are only 20 or 40mm so has me weary of the rare 100mm one available

3) a flexible pan connector..but it would need to be a very short length of flexi

4) is there a better option that 1-3?

Would really love your wisdom on this one! thanks! had been going perfect till i realised this

Just as an FYI, there’s a separate thread on this as well. My pics have disappeared.

The only solution to my mind Fella is to raise the junction so the branch is at the correct height for the pan spigot. Anything else is simply a bodge, and with so much effort put in getting it right to this point, dont give yourself a headache for the future now.

If you haven't got enough room there to get another socket in under the branch to get the correct height, you may have to swap the branch for a solvent weld version, then glue a stub of suitable length into the bottom to give required height.

youre dead right! way too much effort gone into this up to now to fudge such a small detail that could cause me heartache later!

so i got to work this morning and have it sorted now! managed to avoid repair collar too as i was able to wiggle the basin waste free of the boss connector without breaking it! so now i have the perfect height accounting for the floor to come so we are back on track! (photos attached)

thanks again
