Pocster Posted October 29, 2021 Share Posted October 29, 2021 (edited) The original thread Just in case anyone can be bothered to read it. Anyway! I think I have an acceptable solution. Macerating toilet pumps up about 1metre this then runs with a fall for about 14metres until outside into a proper pumping station . On route sink/washer/dishwasher all feed into it. As it's a pumping station I'm guessing this solves the issue . This would work yes??? Edited October 29, 2021 by pocster Link to comment Share on other sites More sharing options...

Mr Punter Posted October 29, 2021 Share Posted October 29, 2021 Can you have a mini pump station near the WC and pipe to the drain in 63mm MDPE? They are almost silent in operation and will probably only operate a couple of times a week. You would need to form a sump for it but ANYTHING is better than a Saniflo.

The ceiling height above the wc is lower than the drain . Also mini pump station needs to be in the floor - can’t because of ufh .

If, my young crapprentice, you allow a fall on the discharge pipe, and you get it wrong, you’ll set up a perfect siphon tube. That’s where the contents of the pipe then suck the turd-scoffing device empty with loads of gurgling and slurping noises ( think of a fat kid on the dregs of his McDonald’s milkshake and you get the idea )…….

Nickfromwales Posted October 30, 2021 Share Posted October 30, 2021 Like it says, if you can run a 32 or 40mm pipe from the point of invert it’ll allow a natural air break. How much of a drop from the muncher to the connection to the SVP? Link to comment Share on other sites More sharing options...

The muncher doesn’t exist - but the pipe from it must run under a window ( which I know is a tad over 1m from the floor ) . Build length is 14m - so I added an additional 2m to get the pump station near the main drain . It’s all just theory based on theory based on guess work . Very technical.
