| 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. This is page 4 of this procedure.
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. |

| Now realign
the diffuser according to your original mark, and tighten the screws. |
|
and ensure
that the impeller does not touch or interfere with the diffuser, by rotating it. |
|
|

 |
| Here I use
Waterlube to guarantee a good seal when the pump assembly is put back together.. |
|
Inspect the
large o-ring for cracks or damage. If it's flattened, it may need to be replaced sometime in
the future. |
|
|
 |
 |
| And of
course, lubricate the main o-ring before re-assembly. |
|
Sometimes,
getting the pump to this point may be a little easier said than done. Patience and
persistence is mandantory here. Be sure the clamp is 'around' the outside rim on the back
side of the pump, (where you can't see it) not slipping between the pump halves. Don't forget to
put the ground wire on first! |
|
|
 |
 |
| Tighten the
retaining band with a deep well wrench, or if your pump has a knob, use your hand to tighten
it. |
|
The gap
between the ends of the retaining band will normally be less than 3/4" when properly
sealed. If the pump leaks, it may help to try tightening it a little more. If you get
to 1/2" and it still leaks, then you need to replace the main o-ring. |
|
|
 |
 |
| While I'm at
it, I also like to remove the pump drain screw, inspect it and the small o-ring for cracks or
damage, lubricate and re-install it. With all this finished now, I replace the pump anchor
bolts into the spa equipment base, refill the spa, check for leaks, power it up, keep my fingers
crossed, then.... relax with a cup of coffee. |
