I have a leak from the bottom of the pump

Also, check for the actual mechanical shaft seal, they leak, and appears as if it's coming off of the wet end. Making it look like the drain plug could be leaking, or the area between the volute which is the pump housing, and the cover, this would normally be a failed gasket or O-ring, depending on the brand. Sometimes just tightening the cover to the pump housing correct this issue.

if you need the impeller and volute you also need seals sounds like it ran without the filter pump on might be better buying a new pump when they get hot they distorte and will leak also PVC pipe is probably distorted youll have to replace the distorted pipe also

Spa motor is leaking

This is something you can do on your own.
The leak is either coming from the shaft seals or from the volute-face plate O-ring.
Most likely it is the shaft seals. You'll need to know the brand of the wet end (pump housing) to get the right seal, the motor manufacture doesn't help.

Thank you for posting your question here on

Your pump seal is the most likely culprit. As the water leaks around the motor shaft it will trickle down to the bottom and drip off. Double check your drain plugs first to be sure it isn't one of them dripping. Assuming they are not, it is the seal.

Waterway pumps use a press-fit 1000 seal. It is not an 'easy' seal change compared to most. You may want to take it to a pump repair shop for the seal change and the shop warranty that should come with it in case it is not done perfectly. If you do it yourself, get a piece of 1" rigid PVC about 8" long with clean-cut squared off ends to use as a driver.

Remove the front pump cover exposing the impeller. Remove the cover plate off the back off the motor to expose the end of the shaft opposite the impeller. Depending on the motor, lock the shaft with a wrench, screwdriver or allen key then spin the impeller off counter-clockwise to expose both halves of the seal.

Remove the old pieces completely and replace them. Put a SMALL bead of silicone caulk along the beveled edge in the seal plate, line up the metal cup making sure you NEVER touch either seal face in the process, and then punch it down with a mallet and the PVC pipe. The ceramic piece can get a small amount of a synthetic lube or just use a little soapy water to ease pressing it into the impeller recess again making sure not to touch the polished seal face. Use clean rags or pieces of paper to cover the seal as you work with it.

Use a synthetic lubricant like magic lube and lay a bead all the way around in the groove the o-ring sits in. Press the o-ring into place causing excess lube to ooze out. Wipe your finger around the whole mess to coat the whole o-ring and then be sure to lube the o-ring on the diffuser.

Once everything is coated the large o-ring should stay in place and the pump half should insert fully into the volute so you can install the band.

How do you replace a seal on a Sta-Rite pool pump? How do you remove the old seal? Ceramic and graphite.

Replacing a shaft seal requires some good mechanical ability.
first, always make sure power is off at the breaker before you work.
You'll have to remove the band holding the wet end to the seal plate. Then remove the diffuser covering the impeller. Remove the cover on the back of the motor. You either need a 7/16 open end wrench or a armature tool to hold the motor shaft while you unthread the impeller (if the impeller has a screw in the middle, you will have to remove it by turning clockwise, left hand threads) counterclockwise. You can then pull the carbon part of the seal off of the impeller, make sure to remove all of it including the metal sleeve. You will then have to remove the seal plate and push the ceramic part out from the back. You can then clean and lube the seal plate and install the new ceramic part of the seal, try not to touch the ceramic with your hands if possible. You can then lightly lube the impeller shaft and slide the carbon part of the seal with the carbon facing toward the ceramic as you thread it on. If the seal plate had a copper heat sink, you can either replace it or use a different size seal. (I believe it's a PS-201) Re-install the seal plate, impeller (and screw if applicable) and diffuser. You should now be ready to mate the seal plate to the wet end. Make sure you fill the pump before you try starting it up, especially with a new (dry) seal.

sounds like you may have an air leak somewhere. If not from your zodiac hose, it may be in the plumbing itself. Check the threaded fitting on the suction side of the pump, check the pump lid o-ring, and depending on the pump, check the gasket between the hair/lint pot and the volute or seal plate (especially if it's a sta-rite).

Removal and installation of diffuser and impeller kit

All jucuzzi pumps are some of the most difficult to repair.Pump front should seperate from body(volute) of pump by means of screws, or some kind of band. Diffuser should have ss screws, or
be held in plsce by notches or both. Impellor spins counter clockwise to come off. Can only remove impellor with impellor wrench, or very strong hand. Rear of motor must be held in place with normally a 7-16 wrench, allen head wrench or screwdriver. Depends on manufacturer of motor. Then impellor can be removed!
Should replace shaft seal under impellor. Can seperate body of pump from motor by turning four outer bolts on back of motor. Must mark rear cover of motor so lines up exact for reassebly. Ussually 1/4 inch socket wrench.Seal can be pushed out from back to front with the corrrect size socket and a very light hammer.
Try to factory Jacuzzi seal, they are better than aftermarket.
Coat rubber on seal with light silicone, and press back into place without touching or marring seal face. Best way is use other half of seal (spring piece) to gently but firmly reseat seal. Examine body from rear to make sure seal seats. Reassemble as taken apart, or just take to a qualified service tech at a well established pool/spa place. Kirk
