Hot Tub Filter Parts, Maintenance & Lifespan

This section will help you understand what to expect when working with hot tubs. I’ll start by describing each part of the hot tub and how to maintain it.

This will include information that will help you know when your filter pieces are nearing the end of their life cycle. Which can help you prevent potential problems.

Hot Tub Pipeline

Lifespan: at least five years and possibly up to ten years.

Maintenance tips: If you’re lucky, you may not have to worry about damaged pipes in your hot tub. But sometimes accidents happen and problems can occur.

For example, if air enters your filter, it can cause significant damage to your pipes over time. Large amounts of debris can pass through a damaged filter and accumulate in the pipes and cause malfunctions.

Listen to the water in your pipes regularly to see if something is out of place. Open the door to the inside of your hot tub and listen to the sounds and also check for strange smells. Do this every few weeks.Dashed Line

Hot Tub Filter Cartridge

Lifespan: At least one year, but not more than three years.

Maintenance tips: Keep maintenance of your filter by cleaning it regularly.

Check your filter cartridge every two weeks to make sure nothing big gets stuck in it.

Change Bath Tub FilterIf so, remove it by hand. Remove your filter cartridge every month and rinse thoroughly with the hose from your garden.

This is a good time to see if the cartridge contains too much dirt or limescale. And also gives you the opportunity to check for cracks or other problem areas.

Every three months, remove the cartridge and immerse it in a filter cleaning solution for at least one hour.

If you have a ceramic filter, you can clean it in the dishwasher at this time. Keeping your filters clean will help ensure that your filter remains functional for as long as possible.

Hot Tub Screws, Washers and Bolts

But you should check them every year to make sure everything is still in place.

As with O-rings and valves, if you think you can not perform these repairs successfully, you should take your filter to a technician or get a professional.

Hot Tub Valves and O-rings

Lifespan: at least five years and possibly up to ten years.

Maintenance tips: O-rings and valves wear out during prolonged use. Check to see if your valves do not work properly if you find air or dirt entering your pipes. If yes, it might unfortunately be too late to solve this problem.

You may need to replace it with something larger and more expensive. Each year, when you replace your filter cartridge, it is time to completely remove the filter and inspect the O-rings and valves for possible damage:

Do they look weak or fragile? You should replace them.
Looking very dirty or viscous? Clean them thoroughly before replacing the filter.

If you are not sure about working with these small parts of the hot tub, call a technician.

Internal Hot Tub Disinfectant

Lifespan: From six months to a year.

Maintenance tips: If you use a disinfectant as part of your filter, you should monitor it to make sure it continues to work as well as possible. In most cases, the disinfectants do not last as long as the media of the filter cartridge.

Cover Life ExtenderTherefore, you should check the disinfectant every two weeks to check for possible damage or problems.

Many modern sanitizers will let you know when it’s time to replace them, but if they do not, replacing them in most cases after six months of use is a good idea.

Never use a disinfectant that has visible damage, as it can damage and potentially alter the balance of chemicals in your hot tub.

Lifespan: at least five years and possibly up to ten years

Maintenance tips: You may not think much about the cover of the filter housing unit. But it really is a very important part of your overall filter functionality. Without this cover, very large debris can easily get into your filter.

Even if your filter cartridge captures these large pieces of debris, they can still cause damage to the cartridge over time.

Which in turn can quickly damage the pump and the interior of the hot tub.

  • Periodically check your cover for signs of looseness or rust.
  • Check the screws to make sure they are tight.
  • Replace any cracked or weakened cover immediately.

Best Hot Tub Filter Companies? My Thoughts.

There are so many different companies in the hot tub industry. This makes it easy to find exactly what you need from a quality manufacturer that you can trust.

And best of all, many of these hot tub filter companies provide warranty of up to ten years.

Mr Water Geek ThinkingNote that Jacuzzi is not the only supplier of hot tub parts. And because it’s a well known brand name, it will probably cost you more.

However, this higher cost can be offset by the fact they provide high quality parts that may significantly increase the life of your hot tub.

But you still have a lot of choice if you don’t have a Jacuzzi brand.

Most hot tub parts are inter-changeable so you can save money by buying products from a lesser known company. Just make sure that it’s from a reputable company that has a good customer track record.

This is where you can refer back to my list of well established hot tub filter companies presented in this article.

Hot Tub CoverHowever, regardless of the company or companies you buy your parts from, remember to keep up with your regular hot tub maintenance.

The combination of good quality parts from a reputable company + regular maintenance = a well running hot tub that will bring lots of joy to you and your family.

Always use a professional technician if you feel unsure about performing a hot tub repair yourself.
