This looks like a great site with a lot of information so I am hoping somebody can help me with a problem. My pump only works for a few minutes before I end up with an air pocket in it and it slows tpo a trickle. I have pulled it apart--no obstructions. It is all the way under water. Any ideas? Thanks!

Welcome to our group!
Is it an external pump? If so make sure the o ring has no nicks, dirt, debris also use some silicone grease on the o ring. They can suck air.

since you think it is the pump ,have you tried another pump .I don't put my submersable pumps on the bottom of the pond .If anything ever happens it could drain the pond .How deep and what sized hose and how many gph pump do you have and how far does it have to pump .Is the pump working right.

Hello and welcome.

Sounds like a submersible pump if it's under water, but I don't understand how a submersible would get an air pocket (what makes you think it's an air pocket?). Please take some close up pictures of the pump -- and BTW, what kind is it?

No, not external...submersed.

It is a Teton. Not real good at posting pictures and stuff but I will try. The reason I think it is an air pocket is that when I unplug the pump, I get a lot of bubbles coming out of it and then when I plug it back in the water flow is better--for a little while.

Where is it drawing water from? maybe one of the inputs is just a touch above water level and enough air starts flowing in to cause the issue.

Sometimes the magnet that drive the impeller just wears out, can be replaced if it's an expensive pump, otherwise a new one with more GPH is in order.

I would think also the impeller .I know gravel can get in the shaft part and needs cleaned out .I know laguna tells you to flush the inside where the impeller goes into and clean the impeller and inspect it closely every 3 months .
