2 Replace the WC first: if the bathroom layout is being altered, with the WC
occupying a new position, this will obviously be the only option as the soil
stack connection will need to be altered before the bathroom installation
can begin. It is pointless installing the original WC on a new soil stack as this
wastes precious installation time.
In both cases, the soil pipe to the WC should be blanked off (temporarily
capped) when there is no WC fitted. This will prevent obnoxious smells from
entering the working area. This can be done by the temporary use of a drain
plug or PVCu cap end.
Once the bathroom suite has been installed, we can think about testing the
sanitary pipework.
