Common Hot Tub Filter Problems

A spa filter is a vital component of any spa system, it's used to remove impurities and particles that can cause issues with the water quality.

There are a lot of things that go wrong with spa filter problems, and these are some of the most common ones that people encounter. As a result, we've compiled a list of the most common issues that people encounter when they're trying to maintain the quality of their water.

 

Stained spa filters

A stained filter can be a good thing if it doesn't affect the filter's capacity or dirt distribution. It can also be a stain that shows up on various parts of the filter.

If your filter doesn't remove oils and other impurities easily, try a good cleaning product such as a spa filter cleaner. It will remove most of the metal stains and oils from your hot tub.

Some stains may still remain after washing and soaking the filter cartridge. However, depending on the thickness of the stain, it can reduce the microscopic filter size to the point where it is not used.

What kind of substance or contaminant is in the water that stains the cartridge? If it is, what kind of treatment s Holes in spa filters

When I was servicing a hot tub for a living, I noticed that its filter cartridge had stitches. A replacement cartridge is recommended if the filter cartridge has no holes.

The question is, what caused the holes in the cartridge? Usually, the lady of the house had installed a pool pump and a spa filter. The latter was installed with holes that were as big as a pencil.

Cracked spa filters

When talking about a cracked spa filter, what it usually means is that the end cap has a split or crack. Aside from that, it can also crack against the central support. These types of issues are rare, but usually require the cartridge to be replaced.

The answer is usually "What caused the end cap to crack?". It could be that the spa filter pump is too big for the filter size.

 

Fuzzy spa filters

If the tips of your pleated fabric are fur-free, then they should be smooth. If they are fuzzy, then they can reduce the effectiveness of your spa filter.

The reason why the cartridge seems to get bent at the edges is usually due to a chemical issue or poor water balance. It can also be caused by improperly cleaning the cartridge.

 

Clogging spa filters

Do your spa's filter regularly clog up again after cleaning? Generally, it will not work as long as the water balance is at or below a certain threshold.

A filter that gets clogged up quickly is most likely contaminated with mineral scale or oil. The easiest way to unclog it is by cleaning with a spa filter cleaner.

If your filter is still clogged after being cleaned, it's probably best to replace it. Also, make sure that the pump is installed properly.

The fibers in your hot tub filter are naturally worn down and cannot filter the smallest particles. Also, they can become coated with oil and crusty deposits that are hard to remove.

Some things to avoid are putting your spa filter in the dishwasher and cleaning it with a pressure washer.
