W/m waste hose connection

[jaydebruyne]

Stupid question time...

Is there any reason you wouldn't connect a w/m to a p-trap with an appliance spigot connected to the half bowl on a 1.5 bowl kitchen sink?????

I'll explain when I get some answers...

I'm intrigued but I'll say no as I've done it. (Cowers waiting for barrage of abuse)

I agree. Both bowls are plumbed with inch an half.. Both teed into the same waste outlet.. So what's the issue???

 

[Riley]

So what've you been told?

 

[jaydebruyne]

Well.. A colleague me told me I shouldnt have done it as the half bowl is too small :/ first time I've heard that one!! He also said that because the underside of the bowl is higher than the main bowl, it can't handle the volume of water pumping out from a w/m

 

[Riley]

New one on me as well. Can't see how that would matter

No issue really. If it has a single trap & both bowls going into it, then no issue where the waste spigot goes whether below the half or full sink bowls.
Only thing I think of is if it has separate traps, then the smaller bowl trap can tend to be blocked with vegetable waste easily.
Any water noise will be as bad in either bowl

What tosh, was he a plumber, this college of yours?

As above it's the trap not the bowl that handles the volume of water from the machine.

Most plumber would agree that the up-stand W/M trap with it's built in air gap & single use is the best way but the spigots are OK bar the additional risk of blocking, so long as the hose is raised up above the over spill level of the machine to guard against siphoning out.

He said it and I thought, this doesn't make sense... Then I doubted myself so thought I'd post it to clarify

You should've said to your mate if it did ever fill the 1/2 bowl it would simply pour into the main bowl haha, sometimes the waste kit under the sink for a one n a half bowl sink usually has the trap at the main bowl side but it's all interconnected so he's speaking poops,

Back flow and glugging as spigot is usually above trap. If traps blocked with fat.......
