Bathroom Fitting

Fitting a saniflo toilet and wash basin.

We have a downstairs bathroom (in an extension on the rear of house) and would like to have a toilet upstairs in the overstairs recess in master bedroom (front of house), we have been told that as we have no soil stack the waste pipe can be fitted into the downstairs toilet and a dergo valve system used. This will avoid the patio being dug up. Is this a safe and normal way of fitting a waste pipe? there is no water connected upstairs as we have a multi-point water heater in the bathroom , we have also been told that the pipe work for the saniflo can go up through the loft space. Can anyone advise if this sounds okay.

Thank you for your reply.

Extending the soil pipe and ending it with a dergo valve is perfectly acceptable.

A dergo valve or air admittance valve prevents back syphon age where a long run of pipework is involved, say the front of a dwelling to the back. If you get the fall in pipework correct then a dergo or air admittance valve is more effective in the long run than a saniflo.
