Handing over a completed system to the

end user

Once all the tests have been carried out satisfactorily, the system operates as
planned, and the work area, appliances and fittings are clean and ready for use,
it is time to hand over to the customer. The customer will need to know how
their newly installed system works, and will need to be given clear information
on how appliances such as macerators, waste water lifters and showers operate.
A full demonstration of how they operate is required, and advice on the
limitations of an appliance’s performance should be discussed in line with the
manufacturer’s instructions.

Decommissioning process for appliances

and systems
When we remove old sanitary appliances and replace them with new ones, we are
decommissioning the above-ground drainage system. In many cases, this will mean
the removal of the soil and vent stack, and waste pipes too. These are procedures
that need careful consideration. The following sections will assess the most
effective way of decommissioning an existing system of above-ground drainage.
