STA-RITE 5P2R-125G with 0.75 HP motor. Had bearings in motor replaced and was advised that shaft seal is also replaced. Now have a leak from the motor side of the seal plate at the bottom. They replaced shaft seal but it is still leaking. I notice from the STA-RITE installation guide that the copper insert(cone shaped) should be replaced.I was told that this part was not needed and that it was not available anymore.I am just wondering whether the absence of this part is now causing this leak.Any ideas as to whether this is the problem or is there any other component that is allowing water to pass back to the outside face of the seal plate. They also metioned that it may that the impeller may be the cause and need replacing.

If they are noisy Yes also replacement of the pump seal is very important. We recomend replacement of the seal every 2 years if pumps is used to vacuum pool.

Your pump shaft seal is leaking and has flushed the grease out of the bearings. Any reputable spa or pool company should be able to replace the bearings and the seal kit for far less than the cost of a new pump. Approx $150.00 to re and re bearings and seal kit.

Hi Tom, The reason your pump is getting noisy is because the motor bearings are worn out. This can also be caused if the shaft seal between the motor and the wet end is leaking. The bearings can't be lubricated because they are sealed. The best solution is to have the bearings replaced as well as a complete seal kit for the wet end.

Your shaft seal has gone bad and water is leaking past the seal, down the motor shaft, and getting into the bearings. The bearings on the motor have started failing and that is causing the squeal. The white powder is calcium buildup. This is caused over time as the water leaks and evaporates, it leaves calcium and any other impurities in the water behind. Had you caught it earlier you could have replaced the shaft seal and saved the motor. At this point you'll need to either replace the motor or have it rebuilt. It may continue to run like that for months, or may go out tomorrow. If your going to rebuild the motor you should do it now before it gets worse. If your gunna replace it, then you can run it as long as the noise doesn't bother the neighbors and the motor doesn't get too hot. Plastic parts inside the motor can actually melt and catch fire. Rebuilt motor will cost ya about 1/2 to 2/3 cost of new motor.

there are a couple of places where the pump may leak. The discharge fitting, the seal plate o-ring, or the shaft seal. If the shaft seal is leaking, water will be dripping from the bottom of the pump where the motor mates to the seal plate.

Did you change the seals? Whenever pump motors are replaced, the ceramic shaft (mechanical) seal should be replaced. Its also a good idea to replace the seal plate and diffuser seals.

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.

You need to change your pump seal. It goes on the shaft of the motor as it enters the rear housing of the pump. If it has been leaking for a while,and started to get really loud you might want to replace the motor while you got it apart.
