Water is leaking out from the hose where it connects onto the top of the pump from the filter; I can’t get it to stop. I’ve tried taking the hose off and putting it back on twice now but water continues to flow down from the connection. Here’s pics 356F8C4C-7E92-40C1-B4B1-E8F6531CA7C0.jpeg38EDDF83-4604-4D90-B302-01AAF6C7539C.jpeg

You probably need to replace the o-ring that is on the bottom of the union. Open the union and look on the hose side of the union for a o-ring, its likely recessed into the plastic. Remove it and take it to the pool store for a replacement. If you know the brand of the union, you can likely find the o-ring online before removing it.

not likely an exact match, but gives you a good idea of what the parts look like: Pentair Union

Our HomeDepot has a decent seection of o rings, not sure if its made just for that union but might be worth looking. If so might be $2 vs $25 ;)
