I have a customer who wants a quote for refitting a 1st floor ensuite. The soil stack drops down into cloakroom beneath and they've mentioned that they sometimes see their sh!te twice 😱!

I've exposed the soil pipe in the cloakroom and can see why....

Upstairs waste is "flying" down the stack, whizzing round the 87.5 bend, occasionally overshooting the cross-branch and showing it's ugly face in the downstairs pan 😡!

What I'm proposing to do is fit a anti-rodent "flap" to right hand socket of the cross-branch to prevent any further crossover from upstairs wc to downstairs wc.

Any comments please?
 
You can buy a form of one way valve for back to back situations like this. It stops it re-appearing in that quite alarming fashion 😱😱😱
