Replace the O-ring or the bleeder valve.

It’s not supposed to spray constantly. If it does, either the bleeder is loose, the O-ring is shot, or the valve body is cracked.

Start by tightening the bleeder by hand — don’t wrench it, you’ll crack the plastic. If that stops the spray, you’re done. If not, take it apart and inspect the O-ring. They dry out and flatten over time. A new O-ring costs a couple bucks and fixes most cases.

If the spray continues with a new O-ring, the valve body is likely cracked from overtightening or age. Replace the entire bleeder assembly. It’s a common part at any pool supply store. While you’re at it, check the filter tank lid O-ring too — that can cause a separate leak that looks like the bleeder is spraying.

This is a ten-minute fix with basic tools. Don’t ignore it — constant spraying means you’re losing pressure and running your pump harder than needed.
