Note that the purpose of this section is to show you how to replace a
spa pump wet end. 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 wet end that you have on your spa is a lot different
from what is depicted here, then do not use these instructions. This is page 1 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. |

Typical spa pump installation. This particular wet end is
leaking due to a failed pump seal. While it is always more advantageous from a cost
standpoint to replace just the seal, it is not always possible to remove the seal and save the
impeller. This repair example covers this contingency, in a worst case situation.
|
If the spa still has water in it, locate and
close water shut-off valves that are connected to the suction and discharge sides of the
pump. In this case, the discharge side shut-off valve is on the other side of the spa heater
and flow switch; (right picture).

On most spas, the pump will have removeable collars that unscrew
from the pump openings. In most cases, you probably won't be able to remove them with your
hands, and may require a nudge with a screwdriver placed on one of the ridges and bumping it with
your fist or palm, or alternatively, a pair of channel-lock type pliers. Once the couplings
have been removed, you need to work on removing the pump motor from the base of the spa.
There may be screws, bolts, or maybe even nothing at all holding it to the base. If the base
plate is metal, and there are metal screws holding it down that are corroded (which is usually the
case), you may be faced with the task of using a hammer and chisel or a drill to drill out the
bottom of the plate or wooden base to pull the bolt through. This is NOT easy!
Take your time and have lots of patience.
When the pump motor is loose, remove the ground wire from the
back or the top of the motor.

Place the pump on the floor or other suitable working surface.
|
Some pump motors may have a shaft cover on the
back. It needs to be removed to gain access to the pump shaft, which we will need to anchor
or turn with a wrench to manipulate the impeller.

Remove all of the face screws from the wet end.

In most cases, it will be required to use a screwdriver or other
thin tool to pry up the edge of the wet end and separate the two components.
Use extreme care to only insert the screwdriver "JUST
ENOUGH" to get the wet end to separate. There may be a seal in this area that could be
damaged. Use the palm of your hand to extend a little more force to the screwdriver if necessary.
|
|
Carefully lift the cover off of the wet end, using
care not to lose any of the screws. If there is a rubber seal around the perimeter of the
cover, then be sure not to lose it.
