Washing Machine Standpipe - no trap

Appreciate that thanks.

The answer to my not very well articulated question is in the video and as Harry Bloomfield and you allude to - this HepvO valve transmits sufficient air

I’ve bought a valve now, will try and attach it to the top of my set up before calling in a plumber if I’m unsuccessful (ie I won’t be cutting pipes!). Wish me luck

I agree, a very basic easy job, diy it. The new valve needs to be installed as low a possible in the pipe, then the pipe you cut off, needs fitting to the top of the valve. Just make sure, you clean off the burrs on the tube from cutting it, so as to avoid damaging the seals on the new valve.

Yes OK it does seem fairly straightforward

Any tips for cutting the existing pipe? Too tight for me to hacksaw...

Rothenberger Industrial 36012 Premium Plastic Pipe Shear https://www.amazon.co.uk/dp/B003S5PIII/ref=cm_sw_r_cp_api_i_8p1QDbD2BHWXG

these any good for an in situ pipe cut?

I would be concerned trying to use anything other than a saw runs the risk of splitting or shattering the pipe. ABS goes brittle with age, whilst fine as it is, it wont withstand attempting to cut it with a pipe shear.

Junior hacksaw? One of those flexible saw wires with finger rings on each end?
