Subject: Please advise for Hot Tub

I bought a 1992 Hot Tub and restored it to use, rebuilding the cabinet,
installing shut-off valves for maintenance without draining the tub,
and replaced a broken heating element. It has a 2 speed motor that
runs on 110volts and a heater that runs on 220volts. The pump runs on
low speed any time the thermostat calls for heat or high speed if user
selected at a switch on the upper console.

Initially the jets provided pressure sufficient for my wife, but
eventually the motor quit working. I swapped it out with a new motor
of the same specs. I took the old motor apart and found the complex
contacts that determine the motor speed had corroded.

Unfortunately, while the new motor is similar, I can't get the
same Jet pressure anymore. Close but not good enough for my wife.
What are my options?

If the new motor is of the same specs, (rpm and horsepower) then the
jet pressure will be the same. These two speed motors are readily
available from spa parts shops.

If the new motor is of the same specs, it may be turning the wrong
direction. Check the rotation on the old and new. Centrifugal pumps will
pump when turning backwards, just not near as good.

Interesting observation. That's one very important spec to get right!

Thanks, Contrary to popular belief in the RV group, I do posses some
knowledge.
