How to Safely Service in Five Key Steps
FILTER OPERATES AT HIGH PRESSURE! When any part of the filtration system is serviced, air can enter the system and become pressurized. Pressurized air can cause the filter lid to violently separate from the filter base, which can result in severe injury, death, or property damage. To avoid this potential hazard:
- Before servicing or adjusting the filter or any other component of the filtration system:
- Shut off power to the pump and any automatic controls at the circuit breaker;
- Open the air relief valve on top of the filter;
- Stand clear of the filter;
- Wait until all pressure is relieved.
- When installing the filter clamp FOLLOW CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
- Once service is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
- Maintain filtration system properly. Replace worn or damaged parts immediately.
- Ensure filter is properly mounted and positioned according to instructions provided.
Backwashing Step-by-step
Backwashing the Filter Without Separation Tank
Use the pressure gauge to determine when to clean your filter. Backwash your filter when pressure reads approximately 10 psi higher than the “Original Starting Pressure,” or when significant reduction in flow is noticed.
01 Shut off pump and relieve all pressure from the filtration system.
- Shut off power to the pump and any automatic controls at the circuit breaker.
- Open the air relief valve at the top of the filter by turning the top of the valve 1/4 turn counterclockwise until it snaps into the full open position.
- Stand clear of the filter and wait until all pressure is relieved. Pressure gauge must read zero (0) psi.
02 Turn skimmer to full skim position and close main drain line.
03 Remove filter pump lid and clean the strainer basket.
04 Reinstall strainer basket and reinstall the pump lid.
05 IF SLIDE VALVE IS INSTALLED:
- Push the slide valve handle down as far as it will go and lock upper pin in cap.
- Open filter air relief valve.
- Stand clear of the filter, then start the pump.
- After a steady stream of water appears, close the filter air relief valve.
- When water from discharge/waste line flows clear, shut off pump.
- Place the slide valve in the FILTER position.
- Proceed to Step 6.
05 IF MULTIPORT VALVE IS INSTALLED:
- Place the multiport valve in the BACKWASH position.
- Open filter air relief valve.
- Stand clear of the filter tank, then start the pump.
- After a steady stream of water appears, close the filter air relief valve.
- When water from the discharge/waste line flows clear, shut off pump.
- Place the multiport valve in the CLOSED position.
- Proceed to Step 6.
06 Follow System Restart Instructions, page 5 exactly.
07 Introduce the recommended amount of D.E. according to Coating the Filter Cartridges with Diatomaceous Earth, page 6. Your filter is now in operation.
Frequently Asked Questions
-
What does a pool filter do?
-
Understanding your pool equipment pad and how everything works together is essential. Think of a pool as a person; the automation system is a bit like its brain, sending signals to the different body parts to ensure they're working accordingly. The chemicals you add to the pool water are like white blood cells, attacking germs and keeping the environment clean. And the filter? That would be the lungs of the pool. Filters take in dirty water, reduce contaminants, and push out cleaner water.
-
Why do I need to clean my pool filter?
-
As pool filters are designed to capture debris, they must be cleaned out periodically. While they are like the lungs of the pool, they're unfortunately not self-cleaning. Before you consider cleaning your pool pump, consult a pool professional. Better yet, call your trusted neighborhood pool pro to handle it for you! Either way, be sure to watch our video on how to safely clean a Quad D.E.® Cartridge Style Filter to understand what the process looks like.
-
How often do I need to clean my pool filter?
-
Unfortunately, there's no easy answer on how frequently you should clean your pool filter. You'll have to consider a few different factors, including the length of your pool season, the amount of debris like leaves and oak catkins in your backyard, and your specific type of pool and filter.
Fortunately, the Quad D.E.® Cartridge Style Filter has a gauge that makes it easy to predict when it's time for a cleaning. Once the pressure gauge shows that the system is running at 10 PSI higher than its starting pressure, you'll know it's time to clean your pool filter.
-
Where can I find information on maintaining my Pentair pool filter?
-
If you have a Quad D.E.® Cartridge Style Filter, we have a video on how to safely clean it. You can also find information on the Quad D.E.® Cartridge Style Filter and other products in the installation and user guides.
With any product, be sure to glance at the warning labels before using it. This label highlights anything you should be aware of, from steps you can take to reduce risk to possible operational errors to avoid. Your safety is essential.
-
What safety issues should I be aware of with pool filters?
-
Your approach to cleaning may vary depending on the type of filter at your pool, so it is important to read and follow manual instructions carefully. One primary safety consideration for all filter cleanings is the risk of trapped air. If air becomes trapped and is not released, it can compress and cause pressure to build. That pressure may cause the lid to separate from the base, which is a serious safety hazard and can be especially injurious if you are standing close.
This is why you should find a pool professional to handle this service. Trained experts know how to prevent this from happening, and they can answer any questions you have about your pool, too. (If you're curious to learn more, however, this and other precautions are outlined in our safety video.)
-
What important step do I need to take before cleaning my pool filter?
-
Before you even think about disassembling your pool filter, put your automation system into service mode to ensure the pump doesn't unexpectedly start. If your pool doesn't have an automation system, you can skip this step.
Next, head over to the breakers in your control panel to turn off power to all pool features. This step is essential, as you want to prevent your pool equipment from turning on until all maintenance is satisfactory.
-
How long does it take to clean a pool filter?
-
You can expect the process of disassembling, cleaning, reassembling, and restarting a pool filter to take at least 60 minutes.
-
What tools do I need to clean a pool filter?
-
Your pool pro will need a ratchet wrench, a 7/8" socket, and a dead-blow hammer for a standard Quad D.E.® Cartridge Style Filter cleaning. You can help them out by having a garden hose with a spray attachment handy, as they will need to spray out the cartridges on a clean, hard surface.
Your pool pro may also occasionally soak the cartridges in a cleaning solution to get rid of oils like suntan lotion. You may see them using commercial filter cleaner or a cup of trisodium phosphate to complete the job.
-
How do I know if the pool filter is not working properly?
-
After service is completed and your filter is restarted, you'll know there's a problem if a solid stream of water does not appear within 30 seconds or if water leaks from the two halves of the filter. If these problems do appear, shut off the pump immediately.
-
