The trouble with acorns and your pool skimmer
You will find that acorns, seed pods and the like can put a damper on a pool skimmer more quickly than your average leaf. They have the heft to sink and are small enough to get wedged in the skimmer throat, while being hard enough to put a strain on the basket. Once the basket is full you will see water flow diminish, the pump has to labor and the filter ends up with more debris than is desirable.
The way to handle it is to stop the debris from getting to the skimmer at all.
Tackling the source of the problem
When tree drop is an issue, the work begins outside the pool. A good seasonal cleanup around the perimeter will do more to stave off clogs than any add-on accessory.
- Put in some time trimming low-hanging branches over the pool where it is safe, or bring in a tree pro for anything more substantial.
- Before the wind or rain can move them into the water, rake or blow the acorns and pods off the deck.
- Make sure gutters, hardscape and planters are clear so storm water does not run organic matter into the pool.
- If a particular tree is a constant nuisance, it may be time to consider pruning or even removal.
Keeping the skimmer basket in good order
Your skimmer basket is the first line of defense. In certain pools a fine mesh insert or skimmer sock will catch the smaller bits before they make it to the opening, provided the accessory is pool-safe and suited to your model. Do not let anything restrict circulation.
- Inspect the basket for any warping, cracks or gaps; a spare should be on hand if the original is in poor shape.
- Swap out a skimmer sock before it tears.
- Stay away from makeshift screens or nets placed in front of the opening. An overly restrictive setup will only compound the problem and cut down on filtration.
Staying on top of it in heavy drop season
In peak periods or when it is windy, the basket needs more frequent attention. Letting it get packed allows debris to compact and block the throat.
To clean it properly:
1. Shut off the pump prior to any access. 2. Take the basket out and empty its contents into a bag or bucket. 3. Give it a rinse with the hose if wet leaves are clumping together. 4. Look for any blockage in the skimmer opening, but never put your hands in there with the pump running. 5. Put the basket back in place and make sure the lid is sealed.
While you are at it, give the pump strainer and filter a once-over as per the manual. There is little point in having a clean skimmer basket if the pump basket is full.
Habits to avoid
Some things can make the job of unclogging a skimmer needlessly difficult:
- Allowing floating debris to sit until it sinks.
- Operating the pump with a broken or absent basket.
- Forcing debris further down the line with a tool or snake.
- Overlooking a weak skimmer or an unexplained loss of flow.
- Introducing chemicals to the skimmer unless the label and manual are explicit about it.
And for safety’s sake, do not be in the pool if the water is questionable or there is an electrical fault at the equipment pad.
When to get professional help
If the skimmer seems to clog on a regular basis, the pump is losing prime, or you suspect a blockage in the suction line or skimmer throat, it is best to call a qualified pool technician. He can inspect for plumbing or circulation issues that are not safe to diagnose on your own and restore proper flow without the risk of damage.
A sensible long-term plan
For the majority of pool owners, the answer lies in a mix of diligent source cleanup and making sure the skimmer basket is intact and checked often during acorn season. Adhere to the equipment and chemical manuals, wear the right PPE and always kill the power to the pump before cleaning. It is the surest way to keep the skimmer from clogging every time a storm rolls through.
