Some pump motor manufacturers in this category leave this value blank or mark it with dots or dashes, allowing pump and spa manufacturers to name them what they want. Try to align the label with the motor, and if not visible, use the pump manufacturer’s decal if available.

Nearly all spa pumps have one of four plumbing fitting size combinations where the hoses connect to the pump; some hot tubs have two isolation or shear valves on either side of the pump, and some pumps have valves on either side of the pump, which means you can close them and remove the pump without emptying the spa.

After installation and connection but before turning on the spa, open the valves to prime the pump and flood the pump and avoid air pockets after installing and wiring but before turning on the spa, close the valves or drain the spa water to prevent all water from spilling out when the pump is removed. After pump piping is tightened, you can start filling the spa.

Suppose the spa is empty or you have closed valves to prevent water from leaking out; slowly loosen the union nuts on the water inlet and outlet of the spa pump. If the pump is bolted to the floor, use a wrench or socket to remove the bolts from the motor footrest. Once you can move the pump, connect the power cord to the spa controller and connect the ground wire to the pump.

Tighten the pump cable clamp where the wires enter the back of the motor and reinstall the end cover or motor cover, remove the plug from the new pump motor side and install the cable connector clamp. Make sure the cable ends are clean to ensure an excellent connection to your new pump.

It is essential to note the wiring configuration on the old pump to a complete and exact match with the new pump. Take a snapshot of how the old pump is connected so that you know where to connect things to the new pump. Then, it will be easier for you to join the motor before inserting the pump under the spa.

However, if the entire pump is older than 2–3 years old, it is recommended that the whole pump be replaced entirely, not just the wet part or motor. 

It may be necessary to remove the corrosion or replace the wiring to get the pump back online.
