WC soil pipe?

[larco]

Hi,

I would like to install a WC in a small room we have.
I wanted to know which size soil pipe fits the WC pan.

Is there a standard size?

Also I would prefer plastic pipe. Any idea of cost per me?

Thanks

Have you planned a route for the pipe?

 

[larco]

yes i have.
There is already a sleeve on the external soil pipe where i can put the waste pipe into. Am I right in thinking that I need to work backwards from the external soil pipe?

I also need to put in a basin. Can I direct the basin waste into the WC soil?
Can this be done after the WC (thinking about the water regs here).

That's usually the best way - and sometimes the only way. You can't exactly spring 110mm pipe into place! Bear in mind that, until you get the pan connected and water in the trap, sewer gas will escape from the open end. If you have to leave the job for more than a few minutes, tie a plastic bag over it.

It would be best to take this straight into the vertical stack by way of a strap boss.

There might be a special tool for this but I haven't got one. Measure carefully, wrap a sheet of newspaper round it so that the edges line up then mark all the way around the paper's edge. That'll give you a square cut end. For the actual cutting I worked my way around with a hacksaw, taking great care not to let it slip. Finally, de-burr the cut end and file a chamfer onto it. This, along with a good dollop of washing-up liquid, will allow it to slide easily into the socket.

NB: You should cut plastic pipe slightly short to allow for expansion. I can't remember how much should be allowed per metre of pipe. I'll try and find out, though somebody else will probably get in first.

You can get straight and bent WC connectors with a boss to run your basin waste pipe into.
