A skimmer basket can look fine from above while it is quietly floating, tipping, or letting leaves slide around the rim. In a UV pool, that matters because bypassed debris reaches the pump basket faster, slows circulation, and can reduce the steady flow your UV chamber needs to sanitize efficiently.
Check basket fit any time the skimmer fills with leaves after wind, rain, mowing, or heavy swimming. Test the water first, then use the Pool Chemical Calculator, iPhone app, or Android app to dose chlorine, pH, alkalinity, calcium hardness, and stabilizer from measured results instead of guessing.
Warning signs the basket is not staying seated
- The basket lifts when the pump starts or when the water level drops slightly.
- Leaves collect under the basket instead of inside it.
- The handle is cracked, missing, or bent enough to catch on the skimmer lid.
- The basket rocks in the well instead of sitting flat on the ledge.
- The pump basket fills with leaves faster than normal after skimmer cleaning.
Why basket weight affects UV performance
UV systems work best when water moves steadily through the equipment pad. A floating skimmer basket lets larger debris reach the pump basket, where it can clog the intake, lower flow, and create uneven circulation through the UV unit. That can leave cloudy water symptoms even when the lamp and chemistry are technically in range.
A seated basket also protects the rest of the system. Keeping leaves, seed pods, hair ties, and small toys in the skimmer reduces pump strain and helps the filter load more predictably. That makes pressure readings more useful and chemical corrections more accurate.
How to check and correct the basket
Turn off the pump, remove the skimmer lid, and lift the basket straight up. Inspect the rim, bottom, and handle for cracks or warping. Clean the ledge inside the skimmer well so the basket can sit flat, then reinstall it and confirm it does not wobble.
If the basket floats when the pump restarts, use a skimmer basket weight or replace the basket with the correct model for the skimmer body. Do not use rocks, loose metal, or anything that can break apart and enter the suction line. After correction, watch the pump basket and return jets for several minutes to confirm flow stays steady.

Can a floating skimmer basket reduce UV pool flow?
Yes. If debris bypasses the basket and reaches the pump, circulation through the filter and UV chamber can drop quickly.
Should I add weight to every skimmer basket?
No. Add weight only when the basket floats, tips, or will not stay seated with the pump running.
What should I use as a skimmer basket weight?
Use a purpose-built skimmer basket weight or a correctly fitting weighted basket. Avoid loose objects that could enter the plumbing.
