3 Things to Check When a Pool Filter Bleeder Valve Sprays Constantly

Tighten the bleeder valve by hand If the bleeder is loose, hand-tightening it often stops the spray. Do not use a wrench, as it can crack the plastic.

Inspect and replace the O-ring A dried-out or flattened O-ring is the most common cause. A new one costs a few dollars and fixes most cases.

Replace the entire bleeder assembly if spray continues If tightening and a new O-ring don’t work, the valve body is likely cracked from overtightening or age. This is a common part at any pool supply store.
