Grey Water pipe connections

[DDJC]

I've got a grey water take off from the tank so I can connect a waste hose. What I am looking for is a 20mm male to 20mm male inline valve; tap or lever. Google yielding nothing so I thought I would ask the experts. Any ideas?

Cheers,

Dave

Maybe something like this?

Like this but in plastic

Thanks for these suggestions. I need them to be threaded male 20mm at both ends. These look like compression fittings. If you take the compression nut off, are you left with 20mm male ends?

They are solvent weld.

Plastic ones are solvent weld don't remember seeing a plastic one with external threads.

Could you nip down to B&Q, or similar, and strip one down to see if it's what you want ?
Always very helpful at my local B&Q despite my irritating questions ......

So is the brass fitting in your picture.
Or at least it needs a flanged pipe and nut.

Yes they make all types. Plain to plain as per example, thread to plain & thread to thread. If you can only get plain then fit these .Plain to thread adapters.

I meant I hadn't seen a plastic valve with external threads which he seems to want

Thanks Gus-Lopez!

This is what I need.

Shame it isn't 20mm, but 3/4 inch and a wind of ptfe tape and I'm done. It's just a drain so there isn't any pressure, so thanks very much for pointing me at these guys.

Cheers, and Happy New Year
