The kitchen island is a notable trend

A large entertaining space is usually the
end game for customers and this will often
require a cloakroom.
Clearly the same drainage issues will
exist but further solutions in the shape of
macerators – the latest of which contain
very quiet pumps – to discharge waste
from WC’s, basins and showers.
If the space is suffi ciently large and
fl exible it is popular to include a sofa bed
so that it can double up as a guest facility.

original bakery and coffee

ovens, surfaces and
commercial sinks with the
waste water being pumped up to the main
soil stack via small bore pipework from
three lifting stations.
The success of the project has now been
extended across the UK so that more
manufacturing and preparation areas

A renowned golf club has expanded its
kitchen facilities to enable it to cater for
larger numbers of visitors. A redundant
room beneath the main kitchen was

waste from the kitchen directly above it.
Without this solution, the room couldn’t
have been converted and it would have
prohibited the expansion of the catering
side of the business.
A former knitwear factory in Leicester
was transformed from factory to restaurant
bar, ensuring the original industrial feel of
the site was retained.
With drainage on the upper fl oor of
the two-storey building, the only way
to successfully convert the basement to

The end game is the same whether in
a domestic or commercial property. It’s
perfectly possible to successfully convert
the basement when you need additional
kitchen facilities, but always consider a
reputable pump manufacturer with the
widest possible range of options so that
there is no compromise on functionality.
In a commercial setting, where
continuity of service is key, choose a
dual pump macerator/lifting station.
If one pump should fail then the other
automatically kicks in to take over until a
fi x is found.
In a domestic setting look for quiet
pumps that have long warranties – for the
utmost peace of mind.
And in all scenarios, it is imperative to
choose a manufacturer with a nationwide
network of service engineers so that call
