Frequently Asked Questions

In the last few days, I have seen bubbles in my pump prefilter: why and what should I do?

There are 2 possibilities:

  • Either there is an incoming air leak in the suction circuit upstream of the pump,
  • or it is a phenomenon known as “cavitation”, generally due to an obstructed pipe.

You therefore need to check the pipes and the seals in the network upstream of the pump.
