Spa Cover Production, Delivery and Return Policies


Voltage ratings for spa components can be confusing. Pump motors are listed as 115 or 230v,
whereas heater elements working in the same system are listed as either 120 or 240v.

Let's just say that any components listed as 110-120 volts are compatible
and any components listed as 220-240 volts are likewise compatible.

Plumbing Size

Refers to the inner diameter of the pipes used in your system (see diagram below).

Pipe Size

IMPORTANT! It's best to enter the INSIDE diameter of your pipe fittings here. However, if you taking your measurements from the wet end, A 3" overall OUTSIDE diameter translates to 2.0" plumbing size while a 2 3/8" OUTSIDE diameter translates to a 1.5" plumbing size.

Control Voltage

Is the power to your spa pack currently 120 V or 240V?

Horse Power

The most common Horsepower for spa pumps is 2HP.
Horsepower rating is often located right on the label of your pump.

We are happy to help determine the HP of your pump, so as always please feel free to call us.


If you need a blower in your pack, please indicate that here.

If you don't need a blower, you save $25.00.
