Build a mini Toilet CDP at home?

[a892374923874]

I'm contemplating making toilet cassette emptying a little easier at home.

I have a circular plastic manhole cover against a wall outside, so I could drill a 110mm hole in it and install a 45deg bend, a drop pipe and a screw cap. If I use a 110mm coupler above the manhole then that will stop the pipe dropping through. I have a fresh water pipe near it to provide a rinse.

However I don't really want any splashes remaining in the area.








Alternatively, we're building a wet room inside, which will have a shower and a toilet, so I could tee off the toilet waste and provide a similar screw cap arrangement in the shower area so any splashes could be rinsed off with the shower. I could provide a separate rinse tap also.

Any other creative plumbing arrangements spring to mind?

I don’t think either of your arrangements would work better than just emptying it down the loo.

Just lift the manhole cover when you want to empty the cassette.

How about just emptying it on site. That’s what I did this morning.

Thanks for the comments . Emptying in the loo generally causes a bit of splashing, which if it was in a location that was covered by the shower would be easier to deal with. Emptying on site doesn't mean I don't have to empty again back home, although admittedly there will be less to empty.

Lifting the chamber cover requires prising it out of the frame with a tool, which I probably shouldn't do too often.

None of this is the end of the world, but I have the opportunity to do something while we're constructing a wetroom, so I thought it was worth considering.
