Losing Prime when vacuuming

[Poconos]

That's a good one Ted. I notice air being sucked in when that part of the vac head is out of the water when I do my steps but never thought it's so easy to mix up the ends.
On the original problem you have to be sure there are no tiny cracks in the hose above the water line. It only takes a tiny, almost invisible crack to let enough air in to lose prime. If you find a crack then you can dry the hose and use cheap electrical tape wound tight to seal the leak. Also use a few layers of tape. Depending on the condition of the hose you may get a lot of additional life from it.

I ended up finding a hairline crack in the bottom of the skimmer housing. I kept noticing water dripping from it, but thought it was just splashing. Replaced that and now it runs like a champ. Thanks for the replies.
