Blocked Hot Tub Filter

My Hot Tub filter blocks quickly, is it faulty?

It is unlikely, so let us investigate why it is getting blocked.

Are you getting water flow errors?

If your hot tub filter gets blocked quickly, the chances are that it isn’t the filter that is the problem.

The filter is doing exactly what it is designed to do, collecting the dirt, debris and contaminants from the water, allowing bathers to enjoy clear clean water.  

Maybe the question should be ‘Why is the hot tub filter getting blocked?’ rather than ‘My Hot Tub filter blocks quickly, is it faulty?’

How does this dirt and contamination get into the hot tub?

Some is environmental, such as dust and dirt blowing about in the atmosphere, pollen, leaves, twigs, suicidal insects etc.

Most of it is transported into the hot tub by the bathers, often unknowingly.

How can I reduce this contamination entering the hot tub?

A few simple steps are all that is required to substantially reduce the contamination introduced into the hot tub.

Check that the hot tub cover fits neatly and securely on top of the tub, ensuring that there aren’t any gaps that would allow access for insects or dust. This also helps to retain heat within the tub. 

Let’s not beat about the bush here. Bathers are responsible for taking much of the contamination into the hot tub. Bathers should always shower before hot-tubbing. 

Care should be taken to reduce the possibility of contamination as far as possible. 

What do people take into the hot tub with themselves? 

The list is quite extensive; hair products (hair spray, colouring, shampoo and conditioner), make-up, tanning products, hair, skin flakes, contamination from clothing etc inc. soaps, detergents, and softeners, deodorants, sweat, dirt carried in on soles of feet, all contribute towards a reduction in water quality. 

All dirt and contaminants can affect the water balance. This all adds to the cost of chemicals required to maintain the water balance, in addition to increased filter cleaning, maintenance and replacement.

Spilled food and beverages also have a detrimental effect on water quality and filter contamination.

Filters

Filters of differing qualities and price are available. There will probably also be a be a significant variation in the performance of the filters.

A cheaper filter may have a smaller area of filter material than a quality filter which may restrict or block flow sooner than a quality filter.

The cheaper filter may also have a poorer quality filtration material and therefore fail to remove the unwanted contaminants efficiently from the water.

Darlly Quality Filters are designed to trap contaminants and debris efficiently. This not only helps to maintain water quality, it also helps protect the workings of the hot tub. Darlly filter material is also tough, durable, and robust enough to withstand repeated cleaning cycles, thus having a significantly longer service life than a cheap filter whilst maintaining its highly efficient filtration capability.

How long should a hot tub filter last for?

As you can imagine, it is undesirable to have contaminated, dirty, and greasy water running through the pumps or contaminating the unseen under-tub pipework and plumbing supplying the jets. Now that could really end up being expensive to remedy!

To enjoy our hot tub experience, what we desire most is clean water. 

By using Darlly quality filters, keeping contamination out of the hot tub by taking a little extra care, and with regular hot tub and filter maintenance, this can be achieved.
