I have another question: I want to channel the rainwater from the left side trench area of the rest bend opening back to the ACOs to the right. For this area (with no footfall) is it ok to put the concrete on top of the pea gravel? There's not enough height for pea gravel and type 1, then...

Hi, thought I’d ask here before jumping two feet in again! What would be my next steps here? The plan is to route the p-trap connection behind the rest bend opening to have the ACOs connected to it running along the house wall. This area will be covered over by decking later. Original...

A little bit gutted about that, but there is a plan B, fortunately! Hopefully can remove that clay elbow clean enough to bed the new plastic in.

Sorry, did you misss the sketch on the right on the pdf showing alternative ? It includes a rest bend up stream of the y branch (in plan) With 2.5deg fall, will waste come back up to the p-trap?

So two separate connections to chamber on existing stack side, existing one for stack and new one for aco’s?

That setup in img_9104 is now concreted in, looking for an alternative pain-free option that doesn't require digging out again.

A possible backup plan: the old stack was connected to the other side of the inspection chamber originally, as shown in img_8964 & 8773, (photos taken before the new gulley, p-trap and stack connection installed, shown in img_9104, which is now concreted in) The existing stack, as shown in the...

Ok, going to have to hope for the best, concreted in yesterday. Did a trial run with water/toilet paper and seemed to flow into the chamber ok, but the proof will be in the ‘pudding’ Not ideal, but will a retrofit non-return flap in the small section of pipe/gulley outlet alleviate problems if...

Will be vented at the top 900mm above nearest window.

It’s a 45deg y-branch pointing downstream directly into the inspection chamber, the location of the channel drainage and the house toilet wastes just wouldn’t allow for the use of a rest bend.

I’m now ready to replace the concrete around the ACOs and gulley/downpipe on this setup but the area is so small I’m not sure how I can compact any fill and also use pea gravel. Will concrete on top of the pea gravel work on this small area?

Floplast have confirmed odours can travel both ways, but not up through the grid. Looking at the cross section detail would suggest this also. Having looked this up, there are some back inlet gulleys that operate in one direction, through differnt height inlet outlet i think.

Spoke to Floplast, this type of gulley is either way and will need trap before aco drain.

Is there a marker on there to say which way round it should be? I took the cap out of one side which I’m assuming was the back inlet but can’t remember which side it was??? The upstand was off cut, just to use as a guide for standout off the wall

Got rainwater, boiler condensate, washing machine and kitchen waste going into that.
