Plumbing Gulley
3.1 Whale have developed a unique pumped drain
gulley that has a profile of 35 mm enabling
shower tray installers to fit the drain in a screed
floor without penetrating the damp-proof
membrane.
When fitting in solid floors, remove enough
material for the installation of the waste water
pipe and gulley. Copper pipe must be lined
externally to prevent corrosion.
Use silicone on top of the seal to ensure
proper sealing beneath tray. Using the hand
tool provided to tighten the locking flange, fit
the gulley cover into the sockets and push
down to secure.
Top Tip: Leave the hand tool in place to prevent
building debris, grout etc. falling into the gulley.
Only remove the hand tool and fit the gulley cover
when the installation is complete.
For alternative gulley options see last section
of these instructions.
3.2 The Wet Floor Kit (BP1578) is the same as the
Standard Shower Tray Kit (BP1558B) apart
from the gulley which is designed for use in
wet floor situations.
Gully supports are provided to maintain the
gully level whilst being installed.
