Spa blower dead, what do I replace it with?

[Theflash95]

My spa blower died recently and I'm looking to replace it. I can't tell what the old one is because the labels on it are all worn/faded. I do know that it is a 240v model as there are two hot 120v wires and then a ground in the electrical box. It looks identical to the Air Supply Silencer... but I have no idea what the HP is.

My spa has 4 jets and is located about 25 feet away from where the blower motor is mounted on the pipe. Do I get a 1 HP, 1.5 HP, or 2 HP replacement?

One horsepower can handle 4-8 jets per the manual. Going larger can overheat the blower. Be sure of voltage before ordering.

Thanks 1poolman1... 1HP did the trick... new blower was delivered today (thank you Amazon for Sunday delivery) and works like a charm... definitely more than powerful enough. Oddly enough the old one didn't have the check valve in place and I have a feeling water backed up into the old one (probably the kids blocking the jets) because it was all rusty inside.

Now it's time to ask the forum about 1 last issue with my setup... one of those 4 spa jets is flowing really slowly. I've taken the eyeball off the end of the jet, but the flow behind it is still weak. Now that the blower works the air seems to be coming out of that jet just much as the other jets, but with the weak water flow the air doesn't shoot into the spa and instead bubbles almost immediately upwards and is very turbulent at the surface.

Start with looking for the orifice being clogged. Drain the spa into the pool and take a look.
