22mm hep2o in to a soil pipe

[Thorfun]

simple one.....how would I go about getting a 22mm hep2o pipe to discharge into a soil pipe?

Poke it in the open end. Sorry couldn't resist that

What about solvent weld overflow pipe. There are adapters off the shelf. Very similar dimensions.

Would you need to know if it was discharging? 

 

I've seen a pressure release dumping Mains water down a drain for months unnoticed.

Should’ve clarified that without leaking would be preferable! 😂

Need something using proper fittings rather than cobbled together with parts of similar dimensions.

sure, but what connectors for 22mm Hep2o to solvent weld?

Nope. Don’t need know. Just need it secure and leak free.

Im not sure if there is a straight to waste from 22?

 

But could you use a small washing machine Rubber drain hose into a macalpine?

@Nickfromwales will the above boss connector work with a hep2o 22mm pipe? i've read before that you said not to use compression with hep2o pipe although others have different opinions on that subject!

actually, this is a stupid question i think! if i'm worried about compression on to the hep2o then i can just couple to 22mm copper and compress that into the above boss connector.

 

sorry for my daftness!

^ that's a rubber waste compression, not  metal olive

Thanks. I ordered one today so will fit it this weekend and will see what happens!

Is the water discharging under pressure? What's the pipe servicing?

Only gravity. This is the discharge from the RWH header tank. If the water has been in the tank unused for a period of time it is flushed out using gravity and replaced. The manufacturer suggests running the 22mm pipe back to the tank so it can be re-used but that’s a long way and I’m not worried about doing that. So I just want to discharge to a soil pipe. 
 

although, now I think about it that water will go straight in to my STP rather than out to the ditch.
