Waste from sink to toilet waste

[mark.carline]

I am replacing the waste from the toilet in my bathroom and the waste pipe goes right underneath my new sink, I wondered - is it possible to connect the waste from the sink to the waste on the toilet ?

possible but make sure you use an anti vac trap on the sink. try this.

is that the one listed as:

"Boss - 90 Degree bend that will accept vented pipe work"

what does it do ?

Cant I just drill a hole in the toilet waste and use a basin pipe connector thing that fits into the hole?

 

[holty]

yes the multikwik will do just as long as you make sure you use an anti vac trap to stop water seal loss or you will get smells

cool thanks for your help guys.

I would also like to use one of these bottle traps:

Does this change things at all ?

I would sooner use a bottle trap as they seem easier to change if theres any blockages.

Is the AntiVac a brand name or does it mean "Anti Vaccum" ?

dont correct me on this but i think mcalpine have the rights for anti vac but others just call them resealing traps not much difference thay all do the same job to stop syphonage
