Thanks Herman! Single-speed pump: Amazon.com Two-speed pump: Amazon.com Variable speed: Amazon.com Just realized that the VSP is 220v, so need to check my electrical. If I've understood you correctly, for the two-speed / variable-speed pumps I should give them continuous power and use their...

I would replace the main pump with a variable speed and the feature pump with a single speed. Does that change things? I'm guessing yes, that it would need RS-485, and I'd be better off going with a single-speed for the main too.

I have two Pentair single-speed pumps (main and water feature) for my ~20k gal in-ground pool. The feature pump is dying, and instead of spending $2000-$2500 to get a Pentair or Jandy professionally installed, I'm thinking of spending $250 for an AquaStrong and paying my plumber $250 to install...

Any luck with this? I'm having the same issue (and did not fully understand the last reply).

(The thing right in the middle is what I'm calling the "valve after the pump")

I left my pool for a month and it got lots of algae. Upon returning, I decided to drain half of it first, to reduce CYA from 100. I then added a ton of liquid bleach (and muriatic acid), refilled the pool, and turned on the pump. I didn't prime it in the usual way (didn't have a hose), but by...

Thanks, everyone. You've put my mind at rest!

The whole motor has been replaced. As far as he can tell, the impeller does spin freely. He did have some trouble finding the right o-rings though!

@bradgray @Poolbreh @wireform Thanks so much for taking a look, y'all. The main question I have is: is it bad? Is it likely to shorten the lifespan (or cause any other problems)? If so, I definitely want to find a solution, because this "fix" wasn't cheap! Here's a more detailed video and then...

Well, the guy I hired wants to try various things to fix it right, and I'd love to be able to point him in the right direction. If people here think it's normal, I'll tell him to stop. Or if nobody knows, I'll let him try things (like replacing the spring). Thanks for your suggestions!

Thank you! If I turn the pump off and then immediately on, it still happens (so no time for new air to get in). Does that narrow it down at all? Anything else I can do to "debug"? Also, is it likely to shorten the lifespan of the motor? If it's just a minor annoyance, I can live with it.

I have a 2 HP SuperFlo (for my water feature) from probably 2007 that I paid a guy to rebuild the motor on. It now makes this terrible reverberating noise when powered on. Any guesses as to what it might be? I'm not sure how best to share audio clips, but I uploaded it here: Water feature pump...

Forgot to say thanks for this reply. After a deeper dive (and learning more about my system), it turned out to be innocent!

Howdy y'all, I'm buying a home with a pool - my first ever. My inspector noticed an issue, and I haven't yet been able to get a pool company out there to inspect. Thought I'd reach out to you experts here to get your opinion. He says: "Looks as if pool pump may be drawing a bit of air from...
