Installing a toilet

someanonbloke

Hi, I want to install a 2nd toilet in my flat.

It's a 2nd floor flat with two levels. It's above a shop.

The main problem is that the room I want to install the toilet is at the front of the flat and the outlet pipe is on the rear.

So the only question is how I connect the toilet outlet to the main outlet?

The room I want to put the toilet in is on the 2nd level of the flat whilst the bathroom/toilet is on the 1st level.

One option for the 2nd toilet could be to fit the outlet pipe through the roof and connect it up with the main outlet pipe. If that's possible.

2nd option would be to somehow connect up the 2nd toilet outlet pipe through the flat (on 2nd level) to connect up with the main outlet pipe. This would involve having to fit a pipe across a stairwell and through a room to get it to flow out the rear of the building.

One of these ?

I'm aware of macerator toilets but it doesn't explain the logistics of the pipes, what is legal/not legal, costs etc etc.

After all, a macerator toilet just turns the waste into slurry so it can be more easily pumped. It still requires pipes to get water to the toilet and to flush the waste away.

I'm no toilet engineer or plumber and so hence my asking here.

The point of a macerator is that you don't need to route a 4" outlet pipe, just a 1.5" which is easier.

A macerator is your only option

The thing is even though they are pumped you still need to maintain a fall on the pipe to allow it to drain away.

The outlet pipework should ideally be 22mm if you run bigger sizes in the pump can't keep the fluid pressurised as well and then you start to get blockages.

You need to know the distance from front to back of your flat to ascertain which pump you require and to see if there is one suitable for your needs, there are min and maximum outlet distances etc.

Have a measure up and a good look at the technical specs on Saniflo site and also Grundfos

When i fitted a shower i put the outlet under the floorboards to get to the outside wall, but for a toilet you really a fast sudden drop. I don't suppose if you're the end of a block of shops you could take the pipe outside and around the building. Those macerator toilets don't get a good name i've seen people on the Internet complaining.
There's no chance of cutting into a drain at the back of the building ??

Unless you can arrange a vertical drop then the slope needs to be quite shallow. If it is too steep the solids will be left behind. This angle is 112.5 degrees, about 1/4inch per foot. Soil pipe connectors are normally made with this angle built in.
