Special Plumbing Situations
24.1
For Systems with Pump Assembly Mounted Well above the Water Level
If you have a very long above ground run of suction line then upon start up you may see the water level in the buffer
chamber drop down to the top of the clear section of the filter, if it drops further the pump will start to churn and
struggle to clear an air/water mixture. If so you will need to increase the volume of the buffer chamber by
lengthening your system at the points shown above, from left to right you will need:
2 x 20mm PVC straight co 1 length of 20mm PVC
2 x 20mm PVC straight co 1 length of 20mm PVC Flexline
2 x 100mm DWV straight co 1 length of 100mm DWV pipe
2 x 25mm PVC straight co 1 length of 25mm PVC
For every 1m extra length of suction line (beyond the 4m recommended max) you will need an extra 50mm length in
the 100mm DWV pipe buffer chamber. DWV
–
(Drain Waist Vent) piping can be purchased at most hardware stores.
The suction line can be an entanglement/drowning hazard if it is fixed inside the pool. For
example a swimmer could get hair entangled at the suction inlet. Always remove suction line
prior to pool/spa use. Only use loose flexible hose and never fix line to any part of the
pool/spa.
