Keep soap and dirt from clogging spout, plunger and valve
mechanism. Clean spout with BobKey and/or remove plunger and

pumped through supply line & valve at regular scheduled intervals.

DuckBill Valves.

1. Conduit is recommended when tracking the supply line through walls, etc
2. To ensure effective operation of soap valve, supply line should be no greater than
1.4m from pump.
3. Thread sealing tape such as Teflon tape or similar is recommended as a sealant
on the exposed thread of the adapter where the valve attaches.
4. Soap Reservoir should always be covered to avoid dust & grit from
contaminating the soap and fouling the dispenser. RBA recommends using part
RBA7730-999-001 Rubber Grommet to house the supply line as it enters the
reservoir.
5. To avoid crushing the reservoir, the lid of the reservoir should be only lightly
tightened, allowing a minute passage of air in, as soap is drawn out.
6. To ensure effective operation of soap valve, supply line should have no crimps or
bends. Extra attention should be paid to the supply tube as it turns down from the
rear of the valve. Also, installers should ensure an additional ‘duck-bill valve’ [part #
B111-15] is inserted into the end of the supply line to assist in maintaining prime.
7. Easy access to the rear of the valve should be provided to allow for maintenance
and repair.
8. Part numbers for remote reservoirs as follows:
RBA7730-999-005 Soap Reservoir, 5L
RBA7730-999-010 Soap Reservoir, 10L
