Solution
Clean the valves or replace them if it is not possible
to remove the build-ups
Position the pump or tank so as to reduce the
suction height
Reduce the suction height or use a pump with a
bigger flow capacity
Check that the ring nuts are properly tightened
Use a pump with a bigger flow capacity or reduce
the suction height
Clean the valves or replace them if it is not possible
to remove the build-ups
Use an opaque PE pipe on delivery
Check the system pressure. Check whether the
injection valve is blocked. Check whether there are
any blockages between the delivery valves and the
injection point.
Check the presence of the foot filter (valve).
If the membrane has been replaced, make sure that
the same is correctly tightened.
Check whether the pump plate data corresponds to
that of the electricity network.
