Degrease Or Deep Clean The Cartridge

How Often Should I Clean My Cartridge Pool Filter?

Hosing and the other methods described above will remove large debris from the cartridge. However, these strategies are not always enough to handle stickier substances like algae, sweat, sunscreen, and body oils that seep into the cartridge materialand interfere with its efficiency.

If your pool and spa get a lot of use with swimmers bringing in these kinds of bather wastes , its a good practice to periodically perform a deeper cleaning. This extra step will provide a more thorough removal of dirt and debris and help maintain the filters effectiveness.

The most common way to achieve good results is with a commercial pool degreaser or cartridge cleaner . These are available at hardware stores, pool supply stores, and online.

To use, spray the product directly onto the cartridge. Be sure to cover all of the surface areas between the pleats. Leave the compound on for the recommended amount of time. Then, thoroughly rinse it off with a hose. If the buildup on the cartridges is particularly dense and nasty, consider soaking them overnight.

There is no hard-and-fast rule here regarding frequency. Some pool owners deep clean every other timewhich may mean only once per year when pool and spa use is high. Others will examine the filter materials to see if material seems sticky or coated, and only if it is, will they use a degreaser.

What’s A Pool Cartridge Filter

A pool cartridge filter is a filtering system that prevents particles from contaminating the water. The system’s heart is the cartridges, tall cylinders made of dirt-trapping fibers. They are housed in a pressurized tank and stabilized by a closure plate. The plate also separates the cartridges and forces water through them. Once the water is filtered, it passes through the collector manifold and exits the tank.

How Often Should A Pool Filter Be Cleaned

Sand and DE pool filters have two levels of cleaning. They can be backwashed, which simply flushes debris out of the filter and removes clogging so they can operate normally, or they can be cleaned, which means removing the filter and manually cleaning it.

Backwashing simply means running the pool pump in reverse for a short time, and is recommended for a quick flush of these two types of filters.

As a general rule, filters should be cleaned in approximately these time frames:

  • Sand pool filters should be backwashed every 1-4 weeks, and cleaned once a year.
  • Cartridge pool filters should be cleaned every 2-6 weeks, with a deep cleaning once a year.
  • DE pool filters should be backwashed every 1-3 months, and dismantled and deep cleaned twice a year.

While regular cleaning and maintenance scheduling depends on the kind of pool filter you have, there are some clear signs that a pool filter needs to be cleaned, no matter what type you have. The reason is because, for all pool filters, as they fill up, they become clogged.

You should always check your filter if the back pressure in your filter system rises, or if your circulation flow rate decreases. So if you notice an increase of 5-10 psi in pressure, or if your circulation drops, its probably time to clean the filter.

You will also want to check the filter if you notice pool water that is cloudy or tinted in color.

Turn Off Your Pool Pump

How To Clean The Pool Filter

Any time youre performing maintenance on your sand filter, you need to start by turning off the pool pump.

This prevents damage from occurring to the plumbing as well as the multiport valve. Also, take note of the PSI level on the filters pressure gauge, which should be 8 to 10 PSI higher than its normal PSI level.

How Often Should I Clean My Cartridge Filter

DarthChicha said:Hi, I have a 10,000 gallon, cement pool in Texas. I bought a new pentair 160340 filter that has cartridges. How often should I clean it? I had read that they should be cleaned every 6 months but the pool guy told me that its every month. :-|Thanks

For your filter, mine has a gauge on top of it. It really depends on your conditions, and how much junk it’s filtering out. My filters gauge was initially setup running at 14 psi, when it gets up around 20 psi, the gauge has a reading that it’s time to clean.

Jeremy — Do not use the dial markings to determine when to clean. Use 25% above clean pressure. Thank you.

Lilypad said:When you have cleaned and reassembled your filter, start it up and note the new “clean” pressure. When it goes 25% above that number it is time to clean. I’ve gone through two of those gauges and am now going to switch to a glycerin one sold by TFTestkits. That black one isn’t very accurate IMO.

How Long Do Pool Filters Last

Your swimming pool pump system can expect to pump 60-70,000 gallons of water every 8 hours. Thats a lot of work!

Like all things, swimming pool filters become less effective with age! When the filter has passed its prime, it will get clogged, dirty, and become ineffective.

How long your pool filter will last ultimately comes down to how much dirt it needs to clean. Assuming you properly maintain your swimming pool, you should expect the below timescales on average:

  • – Filter Cartridge approximately 2,000 working hours, usually around 2-4 years.
  • – Sand Filter Media around 3-7 years
  • – Glass Filter Media about 7-15 years

Cleaning a sand pool filter is relatively easy. You can backwash it, which you should do whenever it reaches 8-10 PSI over the normal operating level. Or youll need to do it when the pool water gets cloudy.

At least twice a year, you should chemically clean your sandfilter with a cleaner that works while backwashing the filter. Heres how:

  • Start backwashing the filter to remove dirt and debris.
  • Slowly add the sand filter cleaner into the skimmer.
  • Backwash the filter for 3 to 5 minutes again to remove dirt and debris that has been dislodged by the filter cleaner.
  • When complete, turn off the filter pump. Move the backwash valve handle to the Filter position and turn the filter pump back on.
  • If you experience water-quality issues after chemically cleaning your filter or backwashing doesnt lower the psi because it may be time to change the sand.
  • See? Quick and easy! With sand filters, you can spend less time cleaning and more time enjoying your pool.
