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.

Want to replace the seal on a water way SD-10-2N11CC

open up the pump volute/housing body, unthread the impeller from the motor shaft. then remove the seal & replace it. NOTE*** ensure that the round doughnut part, dark color, of the seal half (with the spring looking thing) touches the white part of the other half. Most people when changing the seal, believe that the rubber parts of both halves need to touch. that is WRONG. Reinstall and assemble everything back in reverse.

Jacuzzi pump motor leaks at the seal

This means that your pump seals are bad. They are an inexpensive part to replace luckily, but removing the impeller can be tough. There are a number of different Jacuzzi motor/pumps so be sure to get the right seal kit.

The trick is to stop the shaft from spinning while you loosen the impeller. FYI they don't usually come off easily, the older the pump the harder it is to remove the impeller.
On the rear of the motor there is a slot where you can put a flat screw driver into the back of the shaft to stop it from spinning. Once the impeller is off you can remove the volute (rear housing) and change the seal.
Let me know if you need more help.

I have a waterway 48 frame pump that began leaking at the bottowm of the volute. Figured it could only be the o ring causing it to leak, I replaced that, but it continued to leak. Did not seem that the...

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.

How do I remove the Inlet and Outlet PVC pipes attached to the Volute? They may be sealed with a sealant or glue and am not sure if I need to remove the Volute bolts first.

You just have to cut the pipes in a place where you can glue them back together with a coupeling. If you overheated the pump though you may have warped the pipes and will need to go back far enough to get to good pipe and replace it all the way up to the pump. They just screw into the pump and you can seal the new ones with silicone or teflon stick or tape. Don't use pipe dope as it is not good for plastic.
