How to Reduce Debris Reaching Your Pool Skimmer
Reduce skimmer clogging by controlling debris sources, improving circulation, and using covers or barriers so leaves and dirt never reach the waterline.

Dealing with debris at the source
The best way to take some of the work off your pool skimmer is to prevent debris from entering the water in the first place. When a pool is set among trees, shrubs or an open lawn, you will find that small adjustments in the surrounding area have a disproportionate effect.
- Trim back any branches prone to shedding leaves, twigs, flowers or seed pods
- Mow and edge with care so grass clippings are not left to be blown in
- Give the decks, walkways and coping a good sweep before anything can wash in
- Make sure planters, catch basins and trash bins in the vicinity are empty and not spilling litter into the pool zone
Should the wind have a habit of driving debris to one side of the pool, it is worth noting the pattern prior to making any changes to circulation or putting up barriers.
Put up some barriers
There is value in using physical means to stop debris from ever reaching the pool surface, particularly when you are dealing with heavy leaf drop, storms or pollen season.
- A well-fitted cover is essential for an unused pool
- For pools that are exposed to a lot of fallout, a leaf net can handle the larger items
- Put in some landscape edging or windbreaks where it is safe and practical
- Tie down or put away anything loose that could be carried in by the wind
Be sure to read the manufacturer’s directions on covers and nets; they should come off without you having to put the debris right back in the water.
Getting the water to flow to the skimmer
If the skimmer is to do its job, it needs a steady stream of surface water coming to it. Without proper flow, floating matter will be left in the middle of the pool or against the far wall to sink.
- Verify the return jets are directing current to the mouth of the skimmer
- Move adjustable returns as needed to keep debris at the top
- The water level should be in the middle of the skimmer opening, neither too high nor too low
- Time the pump and filter to the level of debris present
When it comes to valve settings or a possible blockage in the skimmer line, do not guess. Refer to the manual or a pool pro.
Maintenance of the skimmer and waterline
Efficiency is key to avoiding clogs. Fine oils and dirt have a way of adhering to the waterline and breaking loose later.
- Do not let the skimmer basket get full; empty it and turn off the pump before you go to it
- The pump basket deserves an inspection as well, as a clog there will hamper the skimmer
- A regular brushing of the corners and waterline is in order
- If large debris is piling up, use a hand net
Gloves and eye protection are advisable for handling wet or sharp material. Adhere to all chemical labels and equipment manuals for routine tasks.
Mistakes to avoid
Certain practices put unnecessary strain on the filtration system:
- Cleaning the basket only after it has clogged
- Operating the pump with blocked circulation
- Using a leaf blower in close proximity to the pool without first removing the debris
- Overlooking roof runoff or gutters that feed the water
- Putting hands in operating suction equipment or other openings
And if the water is cloudy, unsafe or there are electrical concerns with the equipment, swimming is out of the question.
Time to bring in a professional
If you have addressed the sources of debris and improved the flow but the skimmer is still clogging, it is time to make a call. A qualified pool professional can also be of service when:
- You see cracks in the weir door, lid or basket
- There is a suspected suction issue or blockage in the line
- The pump is acting up with odd noises, losing prime or shutting down
- Water levels are dropping for no apparent reason
- Any electrical problems are evident near the pool pad
They will be able to look over the filtration system in a safe manner and put forward the right solution for your particular setup.
