The Surprising Winter Problem That Can Damage Your Pool
When Adam in Penryn walked outside one cold December morning, he noticed the pool water wasn’t moving. The pump was running, but the surface looked still, almost like glass. He shrugged it off and went back inside. Two days later, he found the water level had dropped nearly four inches, and his skimmer basket looked like it had been chewed up.
He didn’t know it yet, but winter debris had created a hidden blockage that slowly strained his circulation system until it cracked a part he couldn’t see. What he thought was “normal winter slowdown” was actually early warning signs of a winter blockage—something many Northern California pool owners overlook.
Winter Debris Builds Up Fast
Winter brings more than cold nights. It brings wind, leaves, pine needles, acorns, dust, and anything that blows across your yard. During cooler weeks, most homeowners assume their pool is safe because no one is swimming. But quiet water plus heavy debris is the perfect setup for problems you won’t notice until spring.
How Winter Blockages Damage Your Pool
When debris sits in your skimmer, pump basket, or filter for too long, the water flow slows down. That slowdown forces your pump to work harder, which raises pressure and increases wear.
Low flow can cause:
Strain on pump motors
Cracked pump lids
Cloudy water
Clogged filters
Air leaks
Early algae growth
In colder months, these problems develop quietly because you aren’t checking the pool as often.
Why Water Flow Matters Even When It’s Cold
Cool water slows algae down, but it doesn’t stop it. You still need movement to keep chemicals balanced and water circulating. Even short daily run times help prevent blockages before they become costly repairs.
Signs of a Hidden Winter Blockage
Watch for:
A pump that sounds louder than normal
Bubbling water at return jets
Skimmer baskets packed with leaves
Water that looks dull instead of clear
A pump basket that stays half-full
Filter pressure suddenly dropping
If you notice any of these, your pool needs attention soon.
How to Prevent Winter Blockages
You don’t need summer-level upkeep, but a few quick steps each week make a huge difference.
Check the Skimmer
Leaves stack up faster in winter. Clear it at least once a week, more during windy spells.
Empty the Pump Basket
Blocked pump baskets cause back pressure. Keeping it clear protects your equipment.
Run the Pump 4–6 Hours Daily
Winter circulation doesn’t need to be long, but it does need to be steady.
Trim Overhanging Trees
Branches that look harmless in fall dump massive amounts of debris during storms.
Use a Pool Cover When Needed
A cover keeps debris out and helps water quality stay steady.
When to Call a Professional
If your pump looks like it’s struggling or you notice the water level dropping, it’s time to bring in an expert. Winter strain can lead to cracked fittings, damaged valves, and filter problems that cost much more to fix in spring.
