New downstairs toilet into kitchen with macerator

[Gadgetman Andy]

Hi all,

We have a fairly large kitchen, and I am thinking about building a small downstairs toilet behind a stud wall in one corner.

I gan get water and power to the room, but the only real access for the waste is going up into the loft with a macerator and tapping into the upstairs bathroom soil pipe.

Saniflow do a model called Saniflowbest which pumps upto 6 metres high, I only need 5 metres so it will be fine I hope?

My only predicament is the waste pipe, can it go outside and up the wall in an insulated trunking or shall I keep it inside and put the trunking on the inside corner of the room and go up that way, which will of course been thopping a whole through two ceilings and my upstairs floor.

Hi

Double check with the manufacturer. However I would locate the pipe outside, there is no need to insulate as the pipe will be empty most of the time (you do not need to insulate a conventional soil pipe)

Your soil pipe in the loft must travel down to the ground somewhere can't you find a lower/closer connection?, your kitchen waste pipe must discharge somewhere.

You will need to apply for Building Regs for this work.

End

Thanks for the reply.

macerators are different and there is fluid within the pipe most of the time unlike a conventional soil stack - so being out side can be an issue
