| Note that the purpose of this section is to show you how to remove &
install a spa pump seal for a Watkins Hot Springs® "Classic"
spa. While every effort is made to be sure that virtually all areas of complexity
are covered, you may find it more difficult or sometimes easier to accomplish this task. Use
common sense. If the pump that you have on your pool or spa is a lot different from what is
depicted here, then do not use these instructions.
Safety Warnings!
| Remove Power from the spa/hot tub BEFORE performing this
procedure. Failure to comply with this requirement, can lead to
electrical shock and/or electrocution! |
Disclaimer
|
| The
instructions here are intended for general reference only. Many pumps
are different from the one depicted here, and may require more or less
mechanical effort or knowledge in order to achieve the desired
results. |

This example
of pump seal replacement is on a Sta-Rite Duraglas® spa pump.
There are three versions of seals/seal kits available. The most inexpensive is the #200 seal
set, show below. The most extensive kit available from Sta-Rite Industries is a complete
rebuild kit, containing all components internal to the wet end.

| We start off by removing the base securing bolt
from the frame support. On a Hot Springs Spa, there is only one used. On a Cal-Spa, you
may find both sides have one on each side. |
|
| Then, using a deep well socket, remove the nut
that is squeezing the securing clamp together. This clamp is what holds the entire pump
assembly together. Remove the nut from the shaft completely and put it
aside. |

On the left, I'm using a flat
screwdriver to pry the metal clamp away from the pump housing. On the right, I'm removing it
completely, taking care not to allow the flex steel to bend outward very much.

| Sliding the back half of the pump assembly away,
I'm removing the small feeder tube from the suction elbow, so I can remove the pump assembly.
This tube serves two purposes, 1, to allow water to flow through the circulation pump suction
tube when the jet pump is running, and 2, to prevent air locks from occuring. Be careful not
to break off the small nipple, or you could have one heck of a plumbing job on your hands to
replace it. |
|
| One thing I've always liked about Hot Springs
Spas, extra long ground and power wires to the equipment! With the pump assembly removed, we
need to remove the ground wire from the motor frame. Sometimes, this is as easy as a thin
tipped flat screwdriver. |
|
|
 |
| ...Invariably, this is not usually the case
though, because with age, corrosion usually sets in on the set screw, requiring the use of pliers
around the outside to remove it. |
