washing machine waste into horizontal WC pipe

[Johnking]

Hi,

I'm planning to site a washing machine next to a WC. The large soil pipe from the WC passes directly behind the washing machine. From reading around it sounds like I could put a boss onto the top of the soil pipe, fit a vertical hepvo trap and a length of 40mm pipe, and dangle the washing machine outlet into that.

Will this work?

Certainly will. Or use a cheaper washing machine stand pipe arrangement.

Hepvo can you use them vertical

Yes. My understanding is it will act as a vented nonreturn valve in place of a trap so the brown stuff can't come up into the washer waste pipe. But I'm less clear about whether the washing machine waste might back up into the WC.

Is it not possible to connect to the vertical soil pipe?

I'd rather not have to put the waste pipe through the wall, it's second story and I don't like ladders! Is there anything wrong with my plan? Would it pass regs?

Ha ha, me neither, I'm ok up until about six rungs.

I'm not sure about the regs, maybe someone else can advise on that but can't see any reason why it wouldn't work. You can connect a basin waste to a soil pipe (have done it and it worked fine) in fact you can buy special toilet pan connectors with a pipe connection boss built in.
