Polaris Booster Pump Troubleshooting & Repair Guide
The Polaris booster pump is the driving engine for the Polaris pool cleaner. The booster pump provides a higher pressure then the swimming pool pump can so it can drive the Polaris cleaning unit. From time to time your booster pump will need some repairs or could have a problems that can only be diagnosed with some booster pump troubleshooting.
Some common things that go wrong with the Polaris booster pump are bad mechanical pump seals, overheated suction and discharge fittings and leaks from the Polaris quick connect fittings. All of these problems can be fixed with a few replacement parts that are available online or from your local swimming pool supply store that carries replacement Polaris booster pump parts.To avoid costly booster pump repairs you should always replace the small parts that are starting to show wear or damage right away. This means if you start to see your pump seal leaking, don’t wait until it gets so bad that you cannot run the pump.
Soon as you see it leak replace it. This goes for anything else you see going bad on the pump. If you feel that something is going to break or looks like its damaged, you will want to shut the pump off right away and fix the problem. Ignoring or “putting off” the problem with the pump will only let the problem become worse and that will usually cost you more money and time to do the repairs.
How To Change The Polaris Booster Pump Seal
The Polaris booster pump seal is located inside of the seal housing. You will have to remove the front of the pump to first access the impeller. Once you have the front of the volute off you will want to now remove the impeller. In order to remove the impeller you will have to grab the back of the motor shaft and then with your other hand you will want to twist the impeller counter clockwise spinning it until it spins completely from the motor shaft.
Now that you have the impeller off you will want to unbolt the seal housing from the frame of the motor. Once you remove the seal housing you can remove the seal base. This is just one part of the mechanical pump seal. The second part of the Polaris booster pump seal will be in the small shaft of the impeller. You will also want to remove this part from the base of the impeller, as you will be replacing both parts of the booster pump mechanical seal.
Once you have removed both the pump seal seat and the spring from the impeller you can replace both parts for the new replacement Polaris pump seal that you have bought. It’s always a good idea to put a tad of silicon on the outer rubber casing of the seal seat. This will hold the seat in place inside the seal housing and also safeguard the seal base from leaking. After you insert the seal base you can slip the other part of the mechanical seal onto the impeller. Now you can turn the impeller clockwise and thread it back onto the pump shaft until it’s tight. Once the Polaris pump impeller is tight you can re-assemble the rest of the Polaris pump as the pump seal has now been changed.
How To Repair Suction Leaks On The Booster Pump
The Polaris booster pump could have some suction leaks in a few common places. The most common places that the booster pump will draw air from is the suction fitting and the volute drain plug. To avoid any air being sucked into the Polaris pump you will want to make sure that you Teflon tape both he threads on the suction fitting and the Polaris pump drain plug.
How To Hook Up The Polaris Booster Pump
The Polaris booster pump can be piped directly into your swimming pools filter system using PVC pipe or it can be installed with saddle clamps that can be connected to the existing swimming pool plumbing. Either way there is only one correct way to hook up the Polaris booster pump.
There is two fitting on the booster pump. The fitting in the front of the pump is called the suction fitting. This fitting will get connected to the discharge side of the swimming pool fitting. This is very important, as you will need to feed the suction side of the Polaris pump with pool water from the filter system. That is why you need to hook it to the discharge side of the pool system. The second fitting or the second connection you will make is to connect the discharge side of the Polaris booster pump to the line that returns back to the pool or to a flexible line that will go to the pool. Whether the Polaris is hooked to the wall fitting in the pool or if its being feed from a flexible like from the top of the discharge side it is important to remember that the Polaris 360, 390 or the Polaris black max are pressure driven units.
How To Turn On The Booster Pump
The booster pump will run if the pool pump is running. This is a safe guard to make sure that the proper amount of water flow is going through the booster pump. As we explained above the Polaris pump needs water from the discharge side of the swimming pool pump so when the Polaris pump is wired by the electricians it should be wired to only come on when the pool filter and pump are running.
To turn on the booster pump you will want to first turn on your swimming pool pump and let it come to full prime. Once the swimming pool pump has been running for a few minutes you can either turn the booster pump timer switch or on use the manual switch that will be located somewhere near the filter system or the timer control panel. Some pools will have both the manual Polaris override power switch and the Polaris timer and some will just have one or the other. Depending on who built your swimming pool will depend on how they wired your Polaris pool cleaning system.
How To Set The Booster Pump Timer
If you have a timer on your Polaris swimming pool cleaner you will want to set it to go on 30 minutes after your pool filter timer comes on. You will want to have the Polaris cleaner shut off about 45 minutes before the filter system does.
To set the timer on the Polaris you first will have to locate the time box. Once you locate the time box you will want to open the timer cover door and inside you will see a dial and two-timer pins. These timer pins will each have a small setscrew in them that you can loosen by hand. One time pin will say off and one timer pin will say on. If you turn the setscrews to the left, which is counter-clockwise you can loosen them and then slide them on the dial to the correct time. Once you have the off and the on pin set you can switch the timer on and if its between those times and the pool filter system is running your Polaris will start working.
Popular Polaris Pump Troubleshooting Questions:
Question: “Does my Polaris Pump filter my pool?”
Answer: No, The swimming pool filter system actually filters the pool but the Polaris unit will pick up and bag the debris inside of the pool.
Question: “Where can I get my Polaris Pump repaired?”
Answer: Most pump or motor repair shops can repair the Polaris pump.
If you have another Polaris Pump question please ask below:
My Polaris works, but the connector broke off in the wall under the waterline. I have all the parts, but can’t get the old female end that has the little knobs broken off (therefore not connection linkage to the hose to the Polaris) out of the wall. Can I use Gorilla Glue on the male end and then just stick it in the water quickly/hold on and hope for a seal and success? Or, what do you recommend as I just can’t get the old piece out of the wall/under the waterline. If I could I have the new Polaris parts to attach to the wall to the hose to the Polaris. Appreciate any advice. s/f Dave
Hi Dave,
I can suggest two options for you, The glue you mention will NOT work for sure.
1) Try using a Polaris wall fitting return tool as pictured here:
Or the second option which is a pool guy trick of the trade:
2) Take a #8 rubber plug and put it into the Polaris fitting and then tighten the wing nut down good.
You can first try to grab the rubber of the plug and then turning it and that may be enough to get the fitting out, In some cases the expansion of the rubber plug inside the fitting will give you all the grip you need.
If not make sure the rubber plug is in there and use a pair of large sized pump pliers and grab the outside of the Polaris fitting and the rubber plug will keep the fitting round preventing it from crushing.
I hope this helps you and let me know if you have any more questions,
Joseph
Thanks, Going to try to borrow a Polaris Wall Fitting Return Tool from the Pool Store or #8 plug at the hardware store. Thanks again, s/f Dave
On my polaris booster pump, the pressure hose at the top blew off. I bought new fittings, but am not sure of the right way to attached and secure the hose. The 3 hook latches of the locking ring “look” like they should lock on a raised ring, about half way onto the part that inserts into the hose. The hose will not insert past this raised ring. The original installation has the other 3 ends of connecting hoses, all are secured a little differently, and none look correct to me…
Hi Todd,
Here is a diagram that explains how to hook up the Polaris Booster Pump hose:
If you need more help let me know, I can also type out how to install the new Polaris hose as well if you like, but I figured a picture is worth a 1000 words ;-)
Joseph
Thanks Joeseph!! You are right – worth a 1000 words!!
and thanks for the immediate response.
I’m still not sure how the red retainer clip helps…seems it should hold the other side of the hose, in case it tries to pop loose… (no retainer clips used in the original install)
Todd
Joseph,
I have just replaced a worn out booster pump but cannot get the new one to work. As soon as I start the pool pump water leaks out of the booster pump space between the impeller and the motor housing. I also cannot get the pump to turn on when the booster switch is turned on. I do not have a booster pump timer.
The new pump is different than the old one in that the three shaft adjustment holes do not appear to be on the new shaft. Assuming that I need to adjust the shaft to keep the water from leaking, is there another way to adjust the shaft?
Thank you,
Mike
Hi Mike,
It sounds like you either have the wrong seal installed or a bad seal in that booster pump?
Is this a new booster pump or did you just change the seal?
Let me know
Joseph
I have a polaris booster pump and have replaced the suction hoses 3 times in the past 12 months. The Pentair 200 PSI hoses continue to fail and begin leaking at the pressurized spring at the end of each hose. These hoses are $35 each and should not fail in such a short period of time. Yes, the rubber washers are new and installed correctly each time. The hose works perfect for 2-3 months then begins spraying a high pressure mist at the connection point. It appears that the pump is producing too much pressure or the hose design is flawed. Any experience or suggestions for this problem?
Hi Steve,
I like to plumb the Polaris with Rigid PVC pipe. You can use SCH 40 OR SCH 80 3/4 PVC pipe.
If you have more questions, Please let me know,

mY PUMP IS LEAKING AT VOLUTE. I CHANGED O RING TO NO AVAIL. I FOUND OUT IT GOT TURNED ON WITH SUCTION VALVE CLOSED . COULD THIS HAVE WARPPED THE HOUSING?
Hi Tony,
Take the Volute back off and get some 100% clear silicone or even “gasket sealer” and coat the o-ring with one or the other and then re-assemble before the silicon drys and you will have a leak free pump,
Let me know if you need more help,

My booster pump is making a loud humming noise while running. not sure if it is the motor or the pump any ideas.
thanks
Hi Barry,
That usually means you need to change the motor bearing, if you need help with that let me know and I can explain how to.
Let me know if you need any more help.

I have a new polaris booster pump. When I turn it on , iot only runs for about 3 minutes…then shuts off… What could be wrong???
Hi Kenny,
Did you have a pool company install the booster pump?
Please let me know and I can help further.

Hello Joseph,
I broke my Polaris Halcyon PB4-60Q main housing. I accidently had the exit valve off and applied house hose pressure to the inlet. It was too much pressure and the main plastic housing split. This is the part attached to the motor.
I cannot find a replacement part because it appears to be connected directly to the motor. Any advice would be great.
Thanks,
Jim
Hi Jim,
What part number in the image below are you looking for?
Let me know
Joseph
Sorry, it’s the PB4-60Q model. Not the regular PB4-60 in your diagram.
Below are links to three photos of the broken pump.
I have the pump taken apart down to the impeller but I’m stuck at this point.

Hello Joseph,
I had a crack and leak in the pump housing of a 180 Booster pump. I installed a new housing, impeller and seals, the polaris is running great, but now the motor shuts off after 5 minutes or so. when it cools down it starts back up, runs for a few minutes and then shuts again. It didn’t start doing this untill I repaired the pump, it does this even if the polaris isn’t connected to the wall fitting. Do you think the motor is just too old to handle the new impeller? should I replace the pump and motor?
Thanks
Hi Philip,
Did you make sure that the impeller was the same as the old one?
Also is the mechanical seal installed right?
Joseph
