How Does A Hot Tub Pump Work?

A pump is an essential element of a spa or a hot tub. No hot water will flow through the jets without it. The water would just sit still.  The pump is responsible for circulating water in the hot tub. Through the filter, the heater and then the jets.
Some tubs have 2 pumps; one for filtering at a low speed and one for sending water through the jets at high speed. The high speed water, however, throws narrow jets so that you can enjoy a nice water pressure overall. This pump is usually powered by a motor.

Hot Tub Pump Buying Guide

When you are about to replace your hot tub pump, there are a few things you must consider. Perhaps the following information will help you look for the right pump:

Horsepower

You can use a pump with a different horsepower than what was originally used but that would change the pressure of the water. Usually, manufacturers choose the hp considering the number of jets in the hot tub or spa. Experts suggest not increasing by more than 1 level in the horsepower. That means if you had a pump with 4 hp, switching to 4.5 hp would be fine. Otherwise, your hot tub might not function properly.

Speed

Your hot tub pump is either going to have 1 speed or 2 speed.  In case you are unable to locate the pump’s speed, it’s ok, you can tell that by how the pump supplies water to the jets.  Push the bottom and see if the jets come on low. Push again; does it take the jets to a higher speed? If yes, then it means you have a 2 speed pump. You can also check the AMPS to determine the speed.

Frame

Pump frame is where the bolts fit and attach the wet end to the motor. The frame is mostly 48 or 56. Check the label. The alphabet “F” represents the frame size. If you can’t find the frame size on the unit, don’t worry, you can measure it yourself too. A 48 size frame is less than inches between the bolts whereas a 58 frame size is more than 4 inches between the bolts.

Voltage

Before buying a new hot tub pump, you must check the voltage of the pump you are planning to replace. Check the label or the instruction’s manual of the pump for that. Remember that not all spas or hot tubs are wired for 240V. Some use pumps 120v. If you don’t check the voltage before buying the replacement pump, you might not be able to use it.

Size of the plumbing

This is the final most important thing you must consider when buying a replacement pump. Plumbing is responsible for taking water into and out of the pump. If you don’t have prior experience in buying a hot tub pump, you might get confused here.
Don’t measure the size of the hole on the wet end to determine the size of the plumbing. Instead, you must figure out the diameter of the PVC pipe within the spa. This size is what you must consider when looking for pump fittings and the pump itself.
Most of the hot tubs have the same size for intake and outtake pipe. It’s recommended to double check that though.

Once you have all this information, you are ready to shop for a replacement pump.

What’s The Right Size In A Hot Tub Pump?

Wondering how to determine the size of the pump? Don’t fret, the process is simple. You first need to look at the sticker regarding specs on your old pump. That should give you all the information you need to pick the right size. They are pretty much the same elements you have already jotted down for buying the replacement pump already but let’s have a look at them again:

1. Frame size

Start by determining the frame size. You will have to measure the area between the bolts. If it’s less than 4 inches that means the frame size is 48 and if it’s greater than 4 inches than it means the frame size is 56.

2. Speed

What GPM will be appropriate to make the jets functions optimally? You can determine that by multiplying the number of jets of your hot tub by the flow rating.

3. Voltage

The pump that has 2 wires in its power supply has a voltage between 110 to 120 volts. On the other hand, if it has 4 wires, you will need a pump with 220 to 340 voltage.

4. Horsepower

It is best to stick to the original horsepower of your pump. Follow the general rule of thumb, do not increase the HP above 1 over the original.

5. Plumbing Size

To determine the size of unions required, measure the pipe’s diameter from both the discharge and the intake.

How To Install A Hot Tub Pump

Once you are sure you have bought the right replacement pump for your hot tub or spa, you will have no problem installing it. In fact, the process is fairly simple. Here is how you can get started:

  • Drain the hot tub before you do anything. It should be completely dry when you are about to remove the pump.
  • Make sure you have some towels with you because some water is going to flow out from the pipes.
  • Detach the copper grounding wire and loosen the fittings of the intake and the discharge.
  • Unscrew the bolts in the frame. Reach the wires and detach them.
  • Place the new pump and wire it properly. Tighten its fittings and bolt back the frame.
  • Once the pump is set, it’s time to test the spa. Refill the tub and watch the water flow.

In summary,

The manner in which water cascades from the jets of your hot tub hinges entirely on the specific pump you opt for. Therefore, it’s imperative to invest substantial effort in selecting the ideal replacement pump. As evidenced, the market offers a plethora of choices when it comes to hot tub pumps; the key is to discern which one is the perfect match for your spa.

By making a well-informed choice from the selection of items reviewed above, you can rest assured that you won’t find yourself plagued by buyer’s regret.
