Pocster Posted September 27, 2022 Share Posted September 27, 2022 (edited) Hi, 1) How do I connect MDPE to the main drain?. I can Tee these 2 together to make one connection. Currently just sat loose . This is for a rainwater pump. I can dig out the main drain pipe for what ever connections are required. 2) I’ve got a sump. Yet this 50mm flowplast connector won’t fit. What should I use ( want solvent weld ) as it’s sewage. Also need to connect to the same main drain as the MDPE pipes above. ta !

Pocster Posted September 27, 2022 Author Share Posted September 27, 2022 (edited) I did find this for the mdpe https://www.gasandwaterpipelines.co.uk/63mm-fittings/63mm-mdpe-110mm-underground-drainage-adaptor-kit.html?kw=&ci=&network=x&pm=&cid=17567543495&aid=&tid=&dev=m&mt=&lim=&lpm=9045627&pos=&dm=&fid=&mid=109646584&pid=PW650&country=GB&source=google&gclid=CjwKCAjwvsqZBhAlEiwAqAHElRjP-t2O6NwzhZdJj3M5n6PuE9Z0-jTmKV0vPgC0VfZw0W8s0gpzWxoCam0QAvD_BwE this for the 50mm ( or whatever it is sump ) https://www.drainageonline.co.uk/above-ground-drainage/soil-and-waste-systems/110mm-push-fit-soil/110mm-x-50mm-solvent-weld-waste-adaptor As they both are end caps ; presume I must Tee the soil pipe ??

Pocster Posted September 27, 2022 Author Share Posted September 27, 2022 Possibly for that 50mm (2" so not 50mm!) to soil pipe? https://www.jtmplumbing.co.uk/pipe-fittings-c433/underground-soil-fittings-c214/jtm-underground-universal-waste-adaptor-p20868 Link to comment Share on other sites More sharing options...
Pocster Posted September 28, 2022 Author Share Posted September 28, 2022 Being good today; answering my own questions as you lot are rubbish 2" solvent weld pipe off the pump discharge. Connection to 110mm soil pipe is done via a 63mm MDPE to 110mm. But this is no good!. Unadvertised though they can supply a 2" solvent weld to 110mm fitting! Those MDPE 2 water pipe I'll Tee together . Then fit a T on the soil pipe. So sewage discharge goes on the end ( it's an end cap fitting ). MDPE goes into the side. PERFECTION!

Nickfromwales Posted September 28, 2022 Share Posted September 28, 2022 Ahhhhh, good times Meantime, down at the ranch….. Is the output under pressure ( pumped ) or gravity? You’d be far better off with a compression 50mm connector IMHO if it’s not pumped. Solvent weld joints don’t have any ‘give’ and can fracture / break free.

The spigot discharge pipe is 52mm solvent weld i.e no thread etc. This is the spec recommended from the sump pump manufacturer. Link to comment Share on other sites More sharing options...

Do they say ABS vs PVC? Or PVC? I’ve fitted a few swimming pools, and the vibration / pump pressure has commanded ABS. What pressure does the pump operator at?

Nickfromwales Posted September 29, 2022 Share Posted September 29, 2022 I think I’d want a rubber coupler with say 2x stainless jubilee clips either side to do that transition. If that spigot ever shears you’re up………ahem………💩 creek. 1 Link to comment Share on other sites More sharing options...

I think the movement of the pump ( jolt ) loosens them - though just as much as a weld joint . How about I solvent weld it and put that rubber coupler on ? 😁 Link to comment Share on other sites More sharing options...

Look for a longer section of 50mm silicone rubber hose and double up on the jubilee clips. Make it so, No.2. 👊 Link to comment Share on other sites More sharing options...
