if it is a used pump, these have a tendency to have a little rust. just get some pump pliers and rock the shaft gently back and forth. then plug it back in.

SOURCE: Jacuzzi jet pump doesn't produce much bubbles

A broken jet internal would allow water to run back up the air lines and contaminate the air lines on all jets that are on the same manifold allowing no air to incorperate into the jets stream resulting in low pressure

SOURCE: Problem with Sta-Rite 5P2R pump

1 year mfgr warranty and a possible stuck impeller (from debris) or bad motor bearing(s)... You will need to disassemble the pump and inspect the impeller by rotating it and check the motor for a seized bearing and bad shaft seal. Replace both bearings and shaft seal may resolve the issue. If the motor and impeller spin freely, then you might have a bad motor start capacitor. Some motors have a mechanical governor that can get stuck on the high speed switch and the motor will not spin until that is repaired. These type of pumps require some knowledge and skill to overhaul. Seek professional assistance to prevent damage.

Something is binding in the pump try the impeller to see if it runs true when you have it apart. It may be cross threaded on the shaft. This is a common problem if you have a air leak in your system.

Thank you for posting your question here on Fixya.com.


It could be the pump is bound up but it is more likely the motor is failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

Sta rite pro jet 3/4 hp seems to be frozen..turn on and it hums then quits ..no water pressure


it sounds like you have a bad starting compositor. If your compositor is a black plastic one look next to the spade connectors in the cap and you'll see a little resest hole with a brown stopper in it. If that stopper is black, burnt or leaking oil it is bad. If you have a metal one you can set it on it's base on a flat surface. If it rocks it is bad. If the compositor is good you may have a problem with the windings and either need to replace the motor or have it rebuilt.

Well pump losing prime


you might have a leak in the foot valve, you can try installing a check valve several inches before the intake to maintain a prime, or check and clean/replace the foot valve.


If the pump ran dry, check the inlet fitting. the pump can get hot and melt pvc piping connected to it, causing air to leak in the inlet side.,

Loud buzzing sound began on start up


It could be several things but the most likely are: Something is spinning around with the motor shaft. Unplug the motor and "blast" water through the vent holes to clear debris. Let it dry completely before returning to service. Something could be caught in the impeller. Remove the front end and check. Squeals, loud hums, heat and vibration are indications of bad bearings.

I have a Sta-Rite pool filter. In the start up procedure, you are supposed to bleed the air until a steady stream of water flows from the air release valve. Although I have confirmed that everything is...


Hi sstanl, Is your pump output or flow normal back to pool? if there is no water flowing through system you will get no expulsion of air or pressure reading on gauge. If pump is working then you probably have a clogged air release valve and maybe a clogged gauge. Just remove air relief assembly from filter top, remove gauge and clear any obstructions in parts. You should easily be able to blow air thru assy with gauge removed. Teflon tape the components and snug them back in their places. restart your pump and voila! air will come out when prime is established.
