So your pool filter is having issues, and also you’re looking for solutions. Nicely, excellent news – you’re in the correct place! Pool filter bother can tackle many kinds, and never all points with filtration are filter issues. Clogged or closed pool skimmers, pumps, or valves can all trigger pool filter issues. Earlier than you get too far into troubleshooting your pool filter, verify for something that could possibly be obstructing water stream to or from the filter. Right here’s a listing of widespread pool filter issues, and the totally different options that may repair it.

Pool Filter Has No Strain
When the pump is off, or when the valve is ready to recirculate or drain to waste, the filter stress must be zero. If the filter stress gauge reads zero or near zero with the pump working, and the valve is in filter or backwash mode, one thing is fallacious. Give the gauge face a flick along with your fingernail to see if it pops up. Examine the gauge dial or face for warping, which might forestall the dial from transferring.

If you’re sure that water is transferring by means of the filter at a traditional price, both the gauge has failed, or there could also be a clog inside the air bleeder meeting that the gauge screws into. To verify, shut the pump off and take away the stress gauge with pliers or a small wrench. Run a stick or small screwdriver down into the outlet to filter any clogs or particles. This can be blocking the stress gauge or air reduction meeting. Pool filter gauges are cheap devices that can fail in time. It by no means hurts to maintain a spare gauge available.
If the water is just not transferring by means of the filter at a traditional price, there’s more than likely a clog or obstruction earlier than the pool filter. It could possibly be a clogged pump basket, impeller, pipe, or skimmer basket. It is also a closed or damaged valve earlier than the pump. In some instances, the pump could have an air leak and is drawing in additional air than water. This will cut back filter stress (and filtration means).
Pool Filter Has Too A lot Strain
In case your filter stress is increased than regular, this normally signifies a unclean pool filter. We typically suggest backwashing your filter (or cleansing your cartridges) when the stress rises 8-10 PSI above the clear start-up stress. The producer’s advice could also be barely totally different, relying on which pool filter you’ve gotten.
In case your stress is way increased than that, there could also be international supplies within the filter (paper merchandise, plastics, mulch, oils) which are actually clogging it up. There is also a closed return valve or bypass valve after the filter. Both situation will trigger the stress to rise to very excessive ranges. The filter or the filter valve (multiport or slide) could have damaged inner components which have lodged themselves within a pipe or becoming. Test the return aspect valves or heater bypass to make certain they’re open. Return pipes or valves after the filter don’t usually clog with particles. However damaged filter or valve components might prohibit the water stream after the filter, thus elevating the filter stress.
Very excessive filter stress could be harmful! Filter lids of clamshell kind filters have been recognized to blow off when the clamp band fails underneath excessive stress. Many pool filters function within the vary of 8-15 PSI, although they’ll generally vary from 3-30 PSI. In case your filter stress has jumped unexpectedly to a better than regular studying, or if the clear/beginning stress is increased than producer suggestions, you might have inner filter issues or filter valve issues. Ensure that all pipes and valves are open after the filter, and in the event you see the stress spike to 40 PSI or increased, shut off the pump instantly.
Pool Filter Strain Rises Too Slowly
Most pool filters will run for a number of weeks earlier than the stress rises 5-8 PSI increased on the stress gauge. Very giant filters may even take months when paired with smaller swimming pools. Nevertheless, some filters can have issues the place pool water bypasses the filter and returns to the pool unfiltered. This will trigger a pool filter stress to rise slowly, and it may possibly take weeks to scrub up antagonistic water situations. In D.E. and sand filters, issues with the filter valve could cause water to bypass the filter. Inner issues (damaged, lacking, or misaligned filter components) inside a filter tank could cause water bypass on all pool filter varieties. As well as, an outsized pool pump can push the filth proper by means of a filter.
Pool Filter Strain Rises Too Quickly

In case your filter stress rises quickly inside hours or days after backwashing, the filter media (sand, cartridge, or D.E. grids) might have consideration. In case your media is clogged with oils or minerals, it would require deep cleansing with a pool filter cleaner cleaner made in your filter kind. In some instances, it’s possible you’ll even want to exchange it with new filter media.
D.E. filters can even see a speedy stress enhance when an inadequate quantity of D.E. powder is used. The identical is true in the event you don’t open up the filter and completely clear the D.E. grids at the very least as soon as per yr.
Throughout very poor water situations, having to backwash day by day or much more typically could be thought of regular. However with clear and clear water, a correctly sized and nicely working pool filter ought to ideally have a filter run of 3-6 weeks between cleanings.
Pool Filter is Leaking Water Round Clamp
As talked about above, clamshell kind pressurized pool filters could be harmful when the stress will get to be too excessive. It is a widespread filter tank design for cartridge and D.E. pool filters, the place there are two halves and a middle clamp to carry the 2 items collectively. If the clamp band is leaking water, it isn’t making a protected seal, and also you’re at an elevated danger for pressurized mishaps.
Shut off the pump and drain the filter tank by opening the air bleeder. Take away the filter clamp band and the filter o-ring, a.ok.a. the stomach band o-ring. Clear the o-ring with water and a rag to take away any filth and particles. Additionally clear the rim of the underside tank the place the o-ring sits. Examine the o-ring for harm. If the o-ring is now not spherical, however triangular in cross part, or whether it is cracked or has dry rot, exchange it.
Lubricate the filter o-ring with Teflon pool lube, and reinstall the highest half of the filter tank. Safe the clamp band round each tank halves and tighten down the nut all the best way, till the springs are touching (new fashion clamps) or the 2 ends of the clamp are inside 1/4″ of one another (older clamps). Tapping the clamp band calmly with a heavy wrench or mallet across the tank whereas tightening improves the seal.
In uncommon instances a tank could warp, stopping seal with the clamp band. On this case, contact your seller or the filter producer for attainable guarantee protection or alternative half numbers.
Pool Filter is Blowing Filth Again Into the Pool
After backwashing, it’s regular for a small quantity of mud to blow into the pool. Utilizing the multiport valve Rinse setting for 20 seconds will repair that downside. For sand filters, a small quantity of nice, silty filth could cross by means of the filter on a regular basis and be thought of regular. Utilizing a filter cleaner or changing the filter sand may help, along with utilizing a clarifier. Simply ensure that it’s not sand that’s coming into the pool. Hit it with a brush, and if it poofs up into the water it’s mud; if it simply rolls round, it could be filter sand escaping by means of a damaged filter lateral.

D.E. filters can lose D.E. powder into the pool (which appears to be like like sandy mud) by means of small tears within the cloth, a free filter grid meeting, cracks within the manifold, or from a lacking air bleeder display or standpipe o-ring. Cartridge filters additionally must be put in correctly into the tank to maintain water from bypassing the cartridge and flowing round it. Once more, there could possibly be holes within the cartridge cloth. Water bypass may also be attributable to an outsized pool pump, improper use of cleansing chemical substances, or from aggressive cleansing with a stress washer.
One other widespread points is attributable to the pool filter valve on sand or D.E. filters. In case your filter valve is in want of restore or alternative, it could possibly be bypassing some portion of the water again to the pool unfiltered.
Pool Filter is Leaking Out of the Backwash Line
It is a valve downside, and never a filter downside. In a multiport valve, the spider gasket and rotor make a seal collectively to stop water from going to the backwash port when the setting is something apart from Backwash. If there’s a trickle or stream of water continuously draining out of the backwash line, open up the multiport valve and examine the gasket. You might discover that it’s twisted, deformed, cracked, or damaged. If the valve deal with is floppy and has little pressure, you might also want to exchange the spring underneath the deal with.
Pool Filter is Not Clearing the Pool Water
Why is the pool nonetheless cloudy? It could possibly be many issues, however let’s begin along with your water stability and sanitation ranges. As we’ve preached on this weblog for a few years, for clear and clear pool water, you want the proper ratio of filtration, sanitation, circulation, and good water stability..
In case your sanitation, circulation, and water stability are spot on, it’s time to look intently on the pool filter. Is the pump working lengthy sufficient every day in your filter to maintain up? Are the pump and filter sized correctly for the pool and for one another? Is there an opportunity that water is bypassing the filter and returning to the pool unfiltered?
In case your pool filter is a bit undersized, or if the filter media is drained, attempt utilizing a clarifier to assist coagulate suspended particles. It’s also possible to use a flocculant to settle suspended particles to the ground and vacuum to waste. In lots of instances the place it takes weeks to scrub up poor water situations, changing the filter media (sand, cartridges, D.E. grids, or D.E. powder) may help tremendously.
Pool Filter is Making Loud Noises
This one’s a little bit of a trick query. Usually in the event you discover a noise on the tools pad, the pool pump is in charge. Whereas in operation, a pool filter is definitely quiet. Loud pool pumps are usually attributable to cavitation (starved for water) or by unhealthy inner motor bearings. A pool pump with an air leak can put a lot of air into the filter. This will generally be just a little noisy because it will get pushed by means of the pool filter. You probably have a continuing stream of air bubbles within the pool, or in the event you can see bubbles by means of the clear pump lid, search for and patch any suction leaks (earlier than the pump) with sealant.
Pool Filter Gained’t Flip On
One other trick query! The pool filter is just not electrical, and solely the pump activates. If the pump received’t activate, it could possibly be entire vary of issues. Search for this reply in our Pool Pump Troubleshooting Information.
