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 damaging the 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. If 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

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

Maintenance suggestions: Like O-rings and valves, you probably do not have to worry about these parts frequently. But you should check them every year to make sure everything is still in place. If the screws are loose, tighten them immediately. If they are oxidized by exposure to water, replace them with more functional screws. The same applies for screws and washers.

These parts are important to keep your filter attached and, in most cases, to keep it in your hot tub. 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. Therefore, 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. Of course, if you visibly break the disinfectant, it means it’s time for a new one. Never use a disinfectant that has visible damage, as it can damage and potentially alter the balance of chemicals in your hot tub.

Hot Tub Filter Housing Lid & Housing Unit

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 working in the world of hot tubs.  So you can see why it is so easy to find exactly what you expect from a quality manufacturer you can trust. And best of all, many of these companies provide warranty for up to ten years.

Mr Water Geek Thinking

Bear in mind that Jacuzzi is not the only supplier of parts for hot tubs on the market. But they are still one of the best options for many hot tub parts.

If you have a hot tub, you do not have to buy products with a Jacuzzi brand. Although it can significantly increase the life of your hot tub if you do so.

On the other hand, if you do not have a hot tub with a Jacuzzi brand, you may be surprised at how many hot tub brand products you can exchange with your hot tub to make it work better than ever.

Remember, however, that buying a popular brand costs more than buying products from a lesser known company. The decision is up to you.

Regardless of the company or companies you want to work with, remember to keep up with the regular maintenance and repair of your hot tub.

Always contact a service technician if you do not feel safe enough to perform a repair yourself.
