Question about Polaris Pb4 - 60 Booster Pump

1 Answer

My Polaris PB4-60 was installed last August brand new. It completed the season working fine. When the pool was opened in the spring the pump is dead, nothing happens when it is switched on. I checked the breaker, the wiring and the ground wire, all are installed properly? What do I check next?

Sounds like it is popping a safety switch or the other issue is that it is getting wet internally from the moisture in the air and is causing the pump to fail, It should technically still be under warranty, I would call the company that replaced the pump or that you bought the pump from and let them know what is going on.

Brand new motor replaced old pb4. After installation it just hums and does not pump. Before installation it works fine without water going through? Any body know what is wrong?

Double check the wiring installation. One wire wrong will stop it. Don't let it hum! Compare old motor to new, are they the same voltage? Can you rotate the motor by hand? It should be free.

I hooked up a new Polaris 280 pool cleaner to replace my Arneson Navigator and it doesn't move.

I would first take it out of the water and check for proper wheel RPM. If it is less than 28 RPM or you are getting no movement at all, it is going to be a problem with the power source. It is likely going to be that your booster pump is missing, malfunctioning, or is not installed properly on the pool cleaner. There are a few other things to check. Clean the skimmer, filter and pump basket, clearing any debris that restricts water flow. Check the hoses, connections and swivels for leaks. Try removing the blue restrictor disk from the UWF or if an adjustable gate valve is installed on the booster pump or cleaner line, open it completely so water can flow freely.

Had Polaris rebuilt last summer. Then wouldn't

Thank you for posting your question here on

Have you cleaned or replaced the in-line filter found at the wall socket? How about the pressure valve found just after the wall it fully open, possibly allowing too much water to bypass the cleaner and return to the pool?

How about the main filter? If overall system flow is reduced because of a dirty main filter the booster pump would be 'boosting' lower than normal pressure so the net result at the cleaner is reduced as well. A cartridge filter is especially problematic here. It can look clean after rinsing it but after enough use the element needs to be replaced to restore original system flow.

Are there multiple return paths for water back to the pool that have valves? Can you throttle down a return to, say a spa for example, to force more water to the dedicated line for the cleaner?

I have a Polaris LR51044 pump that is not working. When I turn it on it "hums" but won't pump water. I live in Baton Rouge, La. and we have had freezing or below freezing weather for the last 2 days. The...

Usually when a polaris booster pump hums it means 1 of 2 things; either the starting capacitor needs to be replaced (its located under the black hump on top of the motor) or the pump is bad. Most likely the starting capacitor needs to be replaces. This is where you should start since the capcitor is only $20-$30. Get a new capacitor from a local pool store, shut the power off to the motor, remove two screws on each side of black hump on top of motor, remove two wires from starting capacitor and install wires on new capacitor, replace cover and turn the pump on. If that doesn't work you will need to replace the motor.

Polaris 280 - tank track keeps coming off

I battled with the track falling off for over a season. The pool guys said they fixed it. Tried the previous solution to adjust middle wheel but no luck. My solution was to remove the left wheel and the tank (to get to the screws). The wheel mount allows for minor adjustment but it is also reversible. Turn the mount around and this will extend the wheel base much more. Mine ran for several hours after doing this and so far the track stays on.
