The pump loses prime, runs noisy and moves less water, and people replace impellers and seals chasing a fault that lives in a ring worth a few dollars. On the filter, the same failure shows as a lid that weeps or sprays under pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the groove, fit the ring dry of grit, and use a silicone based o-ring lubricant.
