So it looks like I can't get a new PB4 where I live (outlawed in CA) but my buddy works for a pool equipment supplier and can get me a good deal on a Pentair Hydroboost. Would that be an acceptable replacement for powering my Polaris 380 pool sweep? (I notice the Pentair is 1hp vs the 0.75hp of my old motor) If so, can anyone chime in on if that's that a good booster pump? Thanks again!!
Good pump. Works well.

Because of not completely understanding Calif. Title 20, many online stores won't ship any pump that is not a variable speed model to California. they are still legal here.

Yeah, that was his understanding of his company's policy but after looking into it more, it turns out he can sell me the PB460 which I understand is a newer version of my 2000 PB4 (not sure if there are any functinal differences). Seems like the Hydrobooster has some nice advantages (quieter, more efficient, cheaper price) but I'm not sure if its worth the risk/hassel of it not enough juice for the pool sweep.

The Hydroboost is a similar design to the Polaris PB4SQ, which is a multistage impeller design, which is supposed to be a lot quieter.

Well I ended up going with the Pentair. The design looks a lot more complex than the old single impeller design. Hopefully that doesn't affect reliability or serviceability. I did appreciate how easy is was to replace the seals on the PB4 and how much online guides/resources there were for it. Still, it was super noisy and the equipment pad is located outside our bedroom so the Pentair should be an improvement.

Where did you hear that a PB4-60 booster pump is”outlawed”in California?I don’t think that is accurate the company is based in Carlsbad,California.Polaris is owned by Fluidra(formerly Jandy).There are local pool companies that carry that pump in your area,I would replace the pump with the same pump personally but that is up to you
 
The law seems to say that the replacement motor for a booster pump has to be variable speed.

However, the government is horrible at writing these things in a way that people can actually understand.

The law seems to apply only to replacement motors for booster pumps, but not to booster pumps.

Maybe it applies to booster pumps.

In any case, booster pumps are not designed to be variable speed.

Booster pumps are designed to work at a specific speed and pressure and using a variable speed motor probably does not make any sense.

Replacement dedicated-purpose pool pump motors means an electric motor that:

Is marketed for use as a replacement motor in self-priming pool filter pump, non-self-priming pool filter pump, or pressure cleaner booster pump applications.

Replacement dedicated-purpose pool pump motors with a dedicated-purpose pool pump motor total horsepower greater than or equal to 0.5 hp manufactured on or after July 19, 2021, shall be variable-speed replacement dedicated-purpose pool pump motors.

California Energy Commission (CEC)​

The California Energy Commission has two rules affecting pool pump motors. Both of these rules were effective July 19, 2021.

  • CEC Title 20 Section 1605.3(g)(5) requires any motor used for residential filter pump applications and manufactured before July 19, 2021 that is greater than or equal to 1.0 THP be replaced with a two-speed or variable speed motor.
  • CEC Title 20 1605.3(g)(6) requires any motor used for replacement dedicated-purpose pool pump motor on all residential and commercial applications and manufactured on or after July 19, 2021 that is greater than or equal to 0.5 THP be replaced with a variable speed motor.

Have installed several. They work well. Actually, any "name branded" booster will work with your Polaris.
Awesome, glad to hear it! It seems like a better pump in several meaningful ways but I was nervous to go with it for fear that it wouldn't be strong enough. I'm glad to hear from someone who has actual experience with it so thanks for sharing your impressions.

I'll post again once I've gotten it installed. Had a bit of a delay due to it not coming with inlet/outlet adapters (I thought it did for some reason when I ordered it).

It should have been included in the pump box it came in,all the booster pumps we have gotten over the years always have them included with it
Yeah, that is what I was expecting too but we opened the box, pulled everything out and found nothing but the pump and instructions. My friend who sold it to me is getting me a hose kit free of charge.

Hose kit and adapters have been included in every one I've installed. Should have been there.
