Re: Crossing (thin) joists with pipes: reinforce?

Pumps are perfectly acceptable and are often used in remote bathrooms. As are toilet pumps. I'd strongly consider it, using 22mm pipe or tube.

I think you'll find your BCO may insist on 32mm solvent weld pipe for pumped waste water. I wanted to use flexible plastic pipe to ease the tortuous route needed and got told no way.

In that case can't you just run it above the floor and box it in?

Apparently there's a door in the middle.

This sounds a good option. Notches in joists to take a waste pipe will be huge. It's not like notching in a water feed pipe ..

Is there? it hasn't been mentioned, however, it would explain the conundrum.

But given the need to traverse the joists at right-angles, I'd only have the depth of the lath-and-plaster on the ceiling to bury a 1.5" diameter pipe!

Thanks. Could you point me at any suppliers of these on the web? I must admit I've never seen them (other than Saniflos)

Sorry, could have explained that a bit better. I was meaning on the wall, in the room below the bathroom, at the top by the ceiling. I've just done something similar today in my downstairs wc.

You could build what (I think) the Americans call a tray ceiling. Where a cross section looks (Sort of) like

This way the boxing goes all the way around the ceiling, and you can hide all sorts of services in there...

I've seen a false floor inserted to solve this problem. Added about 3" to floor level, which was achieved by ramping the entry.
