What to Do If Your Skimmer Basket Keeps Floating Up
A skimmer basket that keeps floating up usually signals low water, a poor fit, debris, or suction problems. Use a safe step-by-step check and know when to call a pro.

Begin with the safest approach
A skimmer basket that will not stay put is usually an indication of improper seating or a problem with water flow. The first rule is to never put your hands in operating suction equipment; do not attempt to yank the basket free while the system is on. Turn off the pump before you even think about opening the skimmer lid.
Once the pump is down, you can open the lid and take out the basket, provided your setup permits safe access. Make sure to have the right PPE on hand, like eye protection and gloves, in case there is broken plastic or other sharp debris in there, and refer to the equipment manual as you work.
Put the water level to the test
More often than not, a basket that floats or pops out is due to low water. When the pool level falls short of what it should be, the skimmer has a tendency to pull in air and create enough turbulence to lift the basket.
There are telltale signs: - The water line is below the centre of the skimmer opening - You see a vortex or air at the throat of the skimmer - The pump is pulling visible air or has lost its prime - Bubbles are coming back from the skimmer into the pool
In such cases, top off the pool to the manufacturer’s specifications, then fire up the pump and see if the basket remains seated.
Give the basket and skimmer a once-over
Sometimes the basket simply does not fit the housing as it should. Even if a replacement appears to be the right size, it may still float once the pump engages. Look for a warped rim, some sun damage, or tabs that are worn out so the piece will not lock in.
Be on the lookout for: - Any cracks on the sides or rim of the basket - Debris lodged under the lip - Broken ledges in the housing itself - A weir door that is jammed or not swinging as it ought to
If the model is wrong or no longer fits with any firmness, put in a proper replacement. There is no point in using makeshift weights or forcing a warped basket.
Suction and flow issues
When the basket is fine with the pump off but comes adrift as soon as it is running, you are likely dealing with a blockage or a change in circulation. A clogged skimmer throat, a dirty filter or a basket full of detritus can all be culprits.
With the pump off, empty and rinse the basket. Then check the valves to make sure they are not sending too much flow through the skimmer, and look for leaves in the throat or buildup in the pump strainer. It is a common error to assume every floating basket is a simple matter of the basket itself, or to run the pump at a high setting without checking the skimmer first.
Time to bring in a pro
You should contact a qualified pool professional if the basket continues to float after you have verified the water level, given it a good cleaning and made sure it fits. This is also the course of action if you spot cracked plumbing, a damaged skimmer body or an air leak that will not go away.
Seek assistance immediately under these conditions: - The pump cannot hold its prime - Water flow is erratic or abnormally strong - The skimmer housing is loose or cracked - There is reason to believe an electrical fault exists
Do not try your hand at electrical repairs or opening up motor parts. If you have doubts about the electricals, shut the system down and get a licensed electrician or pool specialist involved. And do not swim in the water if it is not safe.
Avoiding future trouble
For the homeowner, the aim is a secure basket and consistent circulation. Some good habits will go a long way: keep the water at the right level, do not let the basket overfill, and swap out a worn one before it warps. Ensure the weir door is free to move and heed the chemical labels and manuals.
If the basket keeps making a habit of floating out, the best thing to do is stop guessing, methodically inspect the system and call in an expert when it is more than a matter of a little debris.
