How to choose a hot tub pump

Posted by AxelPrice on April 15th, 2013

Knowing what aspects to follow when choosing a hot tub pump is crucial for the future functionality of your hot tub. Keep in mind that a pump is probably the most solicited from all the hot tub parts and, in consequence, it is mandatory for its features to match with your needs and expectations. So here is what you should always consider.

Made from filters, an impeller and a motor, the pump filters all the water from the system. Practice will show you that for the warm bath to be truly enjoyable, it should include crystal clear water. If you want the best quality you can get, you need to consider some technical aspects.

For example, did you know that there are several types of pumps on the market, depending on their internal structure? You get to choose between single or twin impeller pumps, positive or negative head pumps and regenerative or centrifugal impeller pumps. Since we are not getting into such details at this time, we will only suggest you to ask these questions to a specialized manufacturer or seller. In the meantime, we can focus on several aspects on which a newbie can have more control.

As expected, do not ignore the brand inscribed on the hot tub parts. There are quite a few producers, yet only a few are so reputable that you will bump into them at ease. Trying to read forums and reviews or to discuss with friends that are more into physics than you are, will also help you.

As a rule, the more reliable is the manufacturer, the higher should be the longevity of your hot tub pump. An inspired choice could let you enjoy the pump for several years without problems. And should malfunctions occur, you have more chances to easily replace parts of the pump than to buy a new one. Therefore, ease of replacement is something to look for.

Moving on from names to sounds, we should say a few words about the noise that the pump makes when functioning. While it does not have to be fully silent, if it makes too much noise it is also suspicious. So the sound you should be looking for is a slight hum.

We don’t need to insist on the importance of enjoying a pump with multiple functionalities, but we can specify a major difference: single or multi jet controllable pumps? It mostly depends on the type of hot tub you apply it too. The bigger the tub, the bigger the need for a multi-jet pump.

And we have saved the best for the last: the power of your pump will be essential in determining its physical capabilities. On this chapter, you get to choose in between models from 1.5 to 5 HP. Just like with the previous feature, this one should be chosen according to the volume of water that will be handled.

Still unsure what type of hot tub pump to order? Spend some extra time by researching hot tub parts, read online reviews and even ask a professional for a piece of advice. You know the basics and you can have a sound conversation on this topic from this moment on.
