Below are installation examples showing the versatility of
Lavac system plumbing.
This diagram shows a simple method to use the Henderson Mk V
pump as an emergency bilge pump or sump pump.
The pump body may be rotated to accommodate various mounting
angles.
| Installation # 1 - For craft permanently on waters where overboard
discharge is prohibited. This is a basic system. Use of a
dockside marina pump out station is used or a D.I.Y. outboard
pump can also discharge the holding tank. A-Toilet discharge flow
B-Pump-out flow to quay
C-Discharge to sea
1. Vent/breather pipe connect to 1 ½" ID hose
2. Microvent filter
3. Rinse out facility, connect to ¾" ID hose
4. Vented loop
5. Seacock
 |
| Installation #2 - For craft visiting waters where overboard
discharge
is prohibited. This system is simple to operate. Use of quay side
marina pump out station is not restricted by the on board, in line,
pump. Holding tank contents can be drawn through it. A-Toilet discharge flow
B-Pump-out flow to quay
C-Discharge to sea
1. Vent/breather pipe connect to 1 ½" ID hose
2. Microvent filter.
3. Rinse out facility, connect to ¾" ID hose
4. Vented loop
5. Seacock
 |
| Installation #3 - For craft requiring toilet discharge to sea
or
holding tank and pump-out of holding tank using the one toilet pump.
A-Toilet discharge flow
B-Pump-out flow using Lavac Pump
C-Pump-out flow using Quay side pump.
D-Discharge to sea
1. Vent/breather pipe connect to 1 ½" ID hose
2. Microvent filter
3. Rinse out facility, connect to ¾" ID hose
4. Vented loop.
5. Seacock.
 |
| Installation #4 - An alternate to figure #3. This system
provides a
self pump-out facility to shore or sea, using the one toilet pumps.
When being pumped out by quay side facility this arrangement avoids
tanks contents being drawn through the pump and uses only one sewage
pipe connection to the tank. A-Toilet discharge flow
B-Pump-out flow using Lavac pump
C-Pump-out flow using quay side pump
D-Discharge to sea
1. Vent/breather pipe connect to 1 ½" ID hose
2. Microvent filter
3. Rinse out facility, connect to ¾" ID hose
4. Vented loop.
5. Seacock.
