Despite the many differences between hot tubs, most of them operate in the same way. This closed-loop system prevents stagnation, distributes chemicals, and provides a consistent flow of water for the jets to do their thing.
This process begins with the suction side, which includes the pump (on low speed, for sucking), skimmers, and the filtration system. Next comes the heater and sometimes an ozonator.
The pump is responsible for creating the water flow that powers your heater, and a host of other essential functions. It circulates your water to power your filtration system, helps keep your jets in working order, and creates the turbulence that gives you those delightful hot tub massages. In addition, most pumps have a built-in leaf trap that removes any debris that makes it through the skimmer or main drain. This eases the workload on your filter, and keeps your hot tub clean, fresh and ready to soak in.
A common hot tub pump problem is air in the suction line, which prevents the pump from turning on or circulating the water. Fortunately, this is a relatively simple issue to fix by simply bleeding the air out of the line. Locate your pump and open the lock nut on the discharge pipe, while listening for a hissing sound to let the air escape. Once the pump is able to turn on and re-circulate your water, tighten the lock nut.
Another common hot tub pump problem is an over-sized motor or pump that doesn’t match the specifications of your existing unit. This is a common mistake, and it’s best to look at the specifications of your existing pump when choosing a new one to ensure a proper fit. The most important spec is the voltage, and matching this correctly can prevent severe damage to your new pump or simply make it not work at all.
Tip: When replacing a pump, be sure to save the power cord from the old unit if it’s still operational. This will help to get your new pump up and running quickly and easily.
While price isn’t a reliable shortcut to quality, it is a good indicator of whether your pump was designed to last. Cheaper pumps may not last as long, or even work at all. When shopping for Hot Tub Parts be sure to compare the specifications and price to find the best value. Then you can relax knowing your hot tub is in good hands.
A hot tub’s filtration system is one of the most important aspects of the entire hot tub. This is because it ensures that the water coming into and out of your tub stays clean and sanitary. It also helps to extend the life of your spa pump by preventing it from overworking due to clogging.
There are several different types of filters available on the market today, all designed to serve a specific purpose. The most common are cartridge filters, which consist of a core structure that lends size and shape to the filter and a filter medium wrapped around it. This medium is usually made from polyester and is pleated, which creates a large surface area that helps to trap impurities.
These types of filters are easy to install, clean, and replace. In addition, they’re incredibly inexpensive compared to other filter types. However, the only way to get the most out of a cartridge filter is to maintain a proper maintenance schedule and to make sure that the water in your hot tub is properly tested and balanced.
If the water in your spa isn’t properly balanced, it will put extra strain on your filters and may even damage your hot tub. This is why it’s crucial to follow a strict cleaning schedule and to always keep a good supply of sanitizer.
In addition to rinsing the filter with a garden hose, you can also use a solution of 1:10 muriatic acid to water to help remove calcium deposits from the cartridge. Just be sure to wear gloves when handling the acid and to rinse it thoroughly before using again.
If you’re unsure which type of filter to buy for your hot tub, it’s best to consult your owner’s manual. This will tell you which filter is appropriate for your model and will provide instructions on how to correctly install, clean, and replace it. You can also find out how often your hot tub’s filter should be cleaned and replaced. A dirty filter can cause clogged pumps and other problems that will shorten the lifespan of your hot tub.
The heater in your hot tub is what keeps your water warm. It works by heating the water as it moves through the plumbing system, preventing stagnation and distributing chemicals, while also providing the water needed for the jets to do their thing.
Like the pump, the heater is a vital component in your hot tub. The difference is that the heater in your spa will heat your water with an electric element. This is what makes them so expensive to replace once they fail.
A good quality heater will last you for about 10 years, although they may need to be replaced sooner if you are constantly fighting foaming issues. When the water in your hot tub starts getting foamy, it is typically due to a problem with the heater or the circulation pump. It could be as simple as cleaning your filter, or it could be as serious as a cracked PVC pipe, in which case you’ll need to drain the tub and start from scratch.
PVC pipes run throughout your tub, and are used to send water from the skimmer or filter to the heater and then back out to the jets. The return line also connects to the manifolds, which split up the returning water to the individual jets in your spa. Depending on the size of your tub, you may need one or two manifolds.
The PVC pipes also connect to the ozonator, which uses ultraviolet light or corona discharge (CD) technology to oxidize contaminants in the water. There is a wide selection of ozonators to choose from, based on their output, lifespan and price.
When it comes to replacing your hot tub parts, it’s important to understand how each component works. That way, you will be able to troubleshoot any issues that you might have, such as why your jets aren’t working properly. Understanding the basics of your hot tub allows you to identify the part you need quickly.
While the shell and frame of a hot tub typically last longer than most people expect, your spa’s control system (or “control pack”) will eventually need to be replaced. That’s because it controls everything your hot tub does, including how much water is pumped around the system and whether or not the jets are running.
A typical control pack is a silver tube that sits beneath the pump, filters, and heater. It’s also the brain of your hot tub, controlling everything from circulating the water to turning on lights and music. Some controls have other features, like automatic shut-off and panel locking for safety, fault display that can help you troubleshoot a problem, remote operation that allows hot tub control from a distance, and even built-in sanitization systems.
The suction side of the system is what sucks your water in, and it includes the pump (on low speed for sucking), skimmers, and suction lines. The filtration system then filters and heats the water being sucked in, and the return side pushes clean water back out to your spa. The return side is made up of the pump on high speed for pushing, manifolds, flexible tubes, and the jets.
Each of these parts have different specifications, and it’s important to make sure your replacement part matches the ones already installed in your hot tub. Choosing a replacement part with the right specifications will ensure that your new part works correctly and lasts as long as possible. Luckily, all the replacement parts you’ll find at Easy Spa Parts are guaranteed to meet or exceed manufacturer standards.
