Water leaks around the filter cap or housing

A leak at the filter head is almost always the gasket or O-ring.

Safety first: Switch off the pump, release all pressure (open the on/off valve or bleed-down valve) and lock out before you open any high-pressure part. Never put a hand or tool near a running jet.
