Hot Tub Pump – How it works?

Hot water cannot be flown from the jets, as it will sit still. To ensure a constant water circulation, a hot tub pump is used to take the water from the filter, then heater and finally then via jets. There are many tubs which come with 2 pumps.

While one is used for filtering the water, other propels the water at high speed. Narrow jets are used to circulate the high-speed water through the pump, which is powered by a motor to ensure a constant pressure.

Things you should consider before buying a hot tub pump

For replacing your old pump, following are some of the important factors which one must consider to get the right pump:

Frame

The place where the wet end and the motor gets connected via bolts fit is called the pump frame. Most of the frame varies from 48 to 56. The frame size is denoted on the label as ‘F’. While 48 size frame is 4 inches less between the bolts, a 56 frame comes with 4 inches more.

Horsepower

If you are replacing the pump and satisfied with its water pressure, you should always buy a new pump with the same horsepower. Any difference in the horsepower will directly lead to the difference in the water pressure in your tub.

Horsepower is generally decided on the jet count in the spa or hot tub. It is recommended to not to increase the horsepower more than level 1 i.e., if you are using 4 HP, you should maximize it not more than 4.5 HP to avoid the improper functioning of the hot tub.

Voltage

Appropriate voltage plays an important role in the efficient working of the pump. There are hot tubs which are wired for 240 V pumps and if you try to install a pump with 120 V, it will not work.

Always refer to the instruction manual or label to figure out the right pump volts required.

Speed

The hot tub pumps come in two-speed variants as Level 1 and Level 2. If you are not aware of the seed level of your existing pump, you can figure it out by pushing the bottom.

If jets turn to low, push it again. If your jet is taking higher speed, it implies that it is a 2-speed pump. Another way to determine the pump speed is to check its AMPS.

Plumbing Size

Taking water in and out of the pump accounts to plumbing. The plumbing size is not measured by the hole size at the wet end. The PVC pipe’s diameter within spa determined the plum fittings.

Although you should always cross check, most of the pumps have similar size intake and outtake water pipes.

Installation Guide

Buying the right pump turns insignificant if you are not able to install it properly. The process of installation is easy and simple provided you have a thorough knowledge about it. Here are the few guidelines which can give a good start to your installation process:

• Drain out any water in the tub and ensure it to be completely dry.
• Keep a soaking towel handy to absorb the water outflow from pipes.
• Copper grounding wire to be detached and the fittings for intake and outflow pipes to loosen up.
• Detach the frame and the wires within.
• Put the new pump, wire it according to the instructions provided in the user manual.
• Tighten all the fittings along with bolting back the frame.
• Test the spa by refilling the tub and turning on the pump to observe the water flow.
