8. Connection of bathroom appliances
To connect a shower/bath, ensure that the trap exit is
15cm above floor level. Although not obligatory, a lid
connection may be used to run an external air vent.
9. Discharge connection
Note:
The discharge pipework should be 32mm copper
or rigid solvent weld plastic.
Observe the pumping parameters of the unit (vertical
and horizontal combination, step 4).
All horizontal pipe runs must have a minimum fall of
1:100 (10mm per metre) all the way to the drain.
Technical advice for discharge to lower floor
If the discharge pipework runs to a level considerably
lower than the unit, the resultant siphoning effect
can suck out the water seal in the unit. Fitting an air
admittance valve capable of withstanding 10psi pressure
(BBA approved) at the high point of the pipe run will
overcome this problem.
Orient the opening end of the non-return valve in the
direction of the discharge. Secure with the metal hose
clip (
F
).
10. In case of servicing
For possible service requirements, provide a drain off at
the low point of the installation.
