90 Deg pan connector with waste can I install horizontal?

[Markyuk5]

Hi,

Just putting in a new soil pipe and running waste for sink in the bathroom. I bought a pan connector similar to this:

It's a 90 degree pan connector with integral 32mm boss for waste. Can this be installed horizontally (i.e attach sink waste straight in to it)? Had a sleepless night worrying about sewage running up the sink waste pipe and stinking the house out!

Thanks

Have seen one of them fittings fitted horizontally and yes the 32mm connection was totally blocked with you know what .

I would not fit one horizontally but if you have to connect your basin waste to the back of the crapper,then use this fitting with the 32mm connection UPright.

Brilliant thanks old & bold, had a feeling that might be the case!!

I'll get hold of one of those and hope the u bend on the sink helps to keep the smells out

you need a deep seal trap.possibly with anti vac. https://www.travisperkins.co.uk/McAlpine-A10V-Anti-Vac-Bottle-Trap-32mm-x-75mm/p/961533

Amazing - thanks again Old&Bold.

I've not come across 'deep seal' traps in my very limited exposure to drainage - does the trap with anti vac you linked count as one?

If not - what am I looking out for?

Just came across this old post which mentions best practice is connecting the basin waste at 3X pipe diameter downstream of the toilet connection

If I've got room (I need to double check tomorrow) would this be a 'better' solution?

best practice

Best practice would involve fitting the basin waste pipe run to the vertical soil pipe,its acceptable to feed the basin waste pipe run into the horizontal soil pipe but your original pan/32mm connector would be considered bad practice.

A lot depends on your soil/drainage system,we cant see it or test discharge flows and have to assume its fitted correctly.

Every property has different plumbing arrangements and your installation will be bespoke,so relying on previous threads here could prove unhelpful.

The trap above has a combined anti vac valve (no need to take it apart) and the above wc/32mm connector usually work very well and are considered acceptable.

Happy plumbing
