Hi All

I would like to fit an ensuite to our new house between the two main bedrooms, which are currenltly cupboards, however I'm stumped as to how to get the new soil pipe to the existing pipe.

I have drawn a diagram below of the layout, Now I can see how you would get the soil horizontal to the joists which run across the smaller width of the house, but how do you get them to the corner?

Sorry if its a lame question. It's my first house

It will be hard to do that without a lot of hassle I would have thought. In my house a channel has been created to take an internal length of soil pipe by running a beam parallel to the wall and joining all the floor joists to that - something that's easy to do when a house is being built, but obviously a little harder to retro-fit without some major structural work !

Are you able to run it externally to an alternative sewer drain ? It could either go straight out through the wall on the left or, if the blue square to the right is a shower cubicle, you could reverse the toilet and shower and run it straight out of the wall to the right.

You could run along the joist space to the wall and then along to the drain in the room below the joists and box it in.

Mmm, not sounding too good is it..

The wall to the right is a house, the wall to the left is an external wall but has the stairs in it.

I will have to check to see if the ensuite will overlap with the top of the stairs, then the soil could go outside and along.

Alternatively is it possible to use a saniflow system and then go up across and down?

Hi Tamz

Thanks for that. I will get the plumber to take a look when we move in, it could mean losing an inch or two of the bathroom BUT being able to run a 4" out to the outside wall across the top of the stairs.

Saniflo only. I`m afraid :cry: So look for a sani specialist : they are about - get 3 quotes anyway. Try non-gas plumbers and builders too :idea:

Also consider that what you’re proposing is controlled building work which must comply with several Building Regulations, requires a Building Notice submission, inspection, possible test & sign off by your Local Authority Building Control.

& don't just trust a "plumber" will do it right either, especially any foul drain/sewer connection. :LOL:

Hi Nige

Are you saying that I can only use saniflow even if I can get the pipe out?

Also, Richard. Thanks for the heads up on the building control, I assume I contact the local council for this?

Yes; you need to complete a Building Notice submission which you can get from your LABC or download from their website & submit this along with a fee, calculated on the cost of the work. Depending on what’s involved, they will inspect at various stages (one or two) & then on completion. If it’s got a bath or shower in there it’s usually easier to get the electrical work done by a Part P registered electrician; you can DIY but must notify them at time of submission although, depending on your authority, that route can be fraught with problems. Make sure you understand the BR requirements for drainage, forced ventilation, electrics & sound insulation to stud walls before you start. If a foul drain or inspection hatch is accessible on the other side of the property, it’s usually the easiest option; I would only a Saniflo as a last resort.

If you can get it out across the stairwell - you`d then have to run another soil pipe down to ground /AAv or vent pipe above . Can`t go along and back in to existing one- sorry if you knew this anyway :oops:
