I can't say for sure if it is on your model and I don't rember where it is located. But some of these had impellors that had a allen screw that locked it to the shaft. I know this is not much help but I hope it helps.

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


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.

Hi, I have a waterway executive 48 spa pump and need to replace the seal on the pump shaft. How do I get the impeller off the shaft to access the seal.


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


Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.


To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.


Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

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


Yes...you'll likely find the impeller body has broken away from the motor shaft so even though the motor turns the impeller is not. Replacing the impeller and the seal are not to hard but you may want a shop to do it if you are not familiar with seal replacement. While they have it they can make sure the motor bearings are still OK since the most common reason the impeller breaks is a seal leak that leads to motor shaft and possibly motor bearing damage.

Which way do you turn the impeller to remove ir from the shaft. The part # is 310-4190. Thanks!


Counter clockwise looking at the impeller end. If you can't hold the motor shaft, you might try an impact wrench or using a socket and ratchet sharply strike the wrench.

How do you remove the empellor from the motor shaft? The seal is leaking. I have the 4 screws loose holding the pump casing. Does is slip off the motor shaft or is it threaded on?


First off, are you sure it's the shaft seal leaking and not the Valute (the large o-ring or seal that is in between to two halves of the pump) seal? To clarify, if you get your head down and look at the bottom of the pump while it's running you should be able to see the water coming from the joint between the seal plate, and the seal plate housing, or just behind that from the bottom of the motor probably from the vent holes in the motor housing.

Now to answer your question, assuming it is the shaft seal leaking.... You may have already done some of these steps, if so, sorry - just ignore, but it may help others. To get to the impeller, you need to split the pump into two (the wet end from the dry end) This is done by either removing a large clamp, or removing 4 to 6 bolts depending on the pump. (I'm not talking about the 4 bolts that hold the motor to the seal plate, those come later see below) Once you do this the Motor, seal plate, impeller and diffuser will all pull back away from the front of the pump. At this point it's best to disconnect the electric and remove the whole assembly so you can work on a table or bench. Before removing the impeller you need to remove the diffuser which is screwed over the impeller onto the seal plate with 3-6 small screws. To remove the impeller you need to lock the motor and just unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. One thing to note and/or clarify... in your description you said you have the "4" screws loose... As I mentioned above, most pumps have either a large clamp or 6 bolts holding the two halves of the pump together. In your case I believe it's bolts. Some have 4, but most have 6. Then there also 4 bolts that hold the motor to the seal plate. Just want to clarify that you split the pump in two and remove the diffuser, and impeller, before removing the motor from the seal plate. I haven't worked on a Waterway in awhile, but there are basically the same as many other pumps. You may have 4 bolts, just wanted to clarify from the motor mounting bolts. If something looks different on your pump from my description let me know by leaving a comment and I'll clarify asap. Good Luck!

Leaking #1 pump on Arctic Spas Cub hot tub.


I found out that the pump impeller can be unscrewed from the motor shaft by turning the impeller while keeping the shaft from rotating. There is a brass shaft coupling embedded in the back side of the impeller. This allowed me to remove the leaking seal assembly inside the pump by tapping it out gently. However, instead of just replacing the seal, I decided to replace the entire pump with a newer version. Cost was only about $25 more than replacing the seal and gaskets. The pump-motor assembly has been reinstalled in the spa and there are no more leaks.

How do I get to the pump seal on my hi-flo water


The impeller threads off the shaft and most likely is right hand threads. You will have to lock or hold the motor to remove the impeller. If you remove the motor cover you might find that the motor has a slot in the end of the shaft or two flat sides so you can hold it with a flat wrench.

The impeller is probably plastic and could break. Get a strap wrench to remove the impellor.
