I'm planning on a few new toilets -
what's the best kind of drainage set up
so that its easy to clean if there's ever a blockage?

Should the drainage pipes be directly underneath or to a side?
Should there be an inspection cover or not?

I think we need a bit more information... where are they (ground floor,
first floor).

Are there existing drains, soil pipes? Are you installing new in ground
pipe runs?

Should the drainage pipes be directly underneath or to a side?
Should there be an inspection cover or not?

Do you mean where they connect to the pan itself?

(in a general sense, access points etc generally a "good thing")


Approved Doc H - Drainage and Waste disposal is a good place to start on
piping for soil systems:

yes, a new run,
ground floor.
to be buried under a new floor,
but maybe its better to keep it above the floor until it leaves the house?

the toilet as close the the wall behind it as possible,
the waste running away at right angles.

and possibility of upgrading it to a disabled loo
either later or when built,
im not getting younger!

We have a one way valve at the top of our internal soil pipe boxed in
behind the upstairs loo.

However that isn't the final point in the run of soil pipe so this is
permissible.

The pipe goes under the house, being joined by the pipework from the
ground floor wet room.

It had to be sunk into the far edge of the original concrete raft to get
the correct fall.

Not sure about your question about underneath or to the side.
Normally the soil pipe run is behind the toilet and can be directly behind
or offset, although one I did there was a few feet of horizontal(ish) from
the toilet to the vertical stack outside.

On common solution would be to exit the spigot on the pan with either a
straight or right angle WC connector - then run to the nearest wall and
go through at about the same level. Then on the outside of the wall
connect to a branch fitting with a access plug fitted to the top of it.

e.g:

https://www.screwfix.com/p/floplast-...ck-110mm/29610

https://www.screwfix.com/p/floplast-...ck-110mm/22628

The branch can then drop down to a swept elbow to enter the (near)
horizontal pipe run in the ground.

Look at the back of WCs to gain an understanding of the outlet positions
and then consider the plumbing.

Make sure SWMBO has 'approved' them, or you will be
ripping them all out fairly quickly.

Consider potential problems with "back to the wall" bogs. The pipe gets
hidden.

In my experience, it is difficult to arrange a local accessible
isolating valve.
