Suction Plumbing Configurations Not Allowed
The by-pass line comes with a 3mm inner constriction encased in a clear PVC line. This
may need cleaning at some point.
Warm the PVC around the barb with hot water and
twist, for easier removal from the barb
The guiding principle here is that all suction lines must
automatically, fully and completely
flood prime, evacuating all air.
It is not sufficient to clear an air trap in the system by forcing
water through. Air can be reintroduced when the system drains down through the pump.
No air traps in lines are allowed, except for the inverted strainer which automatically self
purges air via the installed by-pass line.
