Cause
Cleaning the non-return valve
Sand can block the non-return valve of the
pump so that it cannot close properly. The
non-return valve has to be cleaned.
Prerequisite:
• The pressure hose and adapter have
been dismantled.
How to proceed:
 D
1. Carefully pull out the non-return valve
with pliers.
2. Thoroughly clean the non-return valve
with clean water.
3. Reassemble in the reverse order.
4. Prior to installing, allow the pump to
convey clear water for a few minutes
(e.g. in a basin) to completely remove
any sand residue. (→ Installation and
connection)
