    How to Winterize Your Pool in Northern Nevada

    Pool owners in warmer states can get lazy about closing season. In Carson City, you can't. Our winters bring hard freezes, and water that freezes inside plumbing or equipment expands — cracking pipes, pump housings, and filters. Proper winterizing isn't optional here; it's the single best way to avoid a very expensive spring surprise.

    Time it right

    Wait until water temperatures are consistently cool (generally below about 60°F) before closing. Closing too early, while the water is still warm, invites algae to grow all winter under the cover. Closing too late risks an early freeze catching you unprepared.

    Balance the water first

    Before you close, get the chemistry right — pH, alkalinity, calcium hardness, and sanitizer. Water that sits all winter out of balance can stain or scale the surface, and you'll be fighting that in spring. Balanced water going in means far less work coming out.

    Clean it thoroughly

    Skim, brush, and vacuum so nothing organic is left to decompose under the cover. Leaves and debris left in the pool all winter are exactly what turns water into a swamp by April.

    Lower the water level and clear the lines

    This is the freeze-protection step that matters most. Water is drained below the skimmer, and lines are blown out and plugged so no water remains to freeze and crack. The pump, filter, and heater are drained as well. In our climate, missing this step is how people end up replacing equipment.

    Winterize the equipment

    Drain the pump, filter, and heater fully, remove drain plugs, and store them somewhere you'll find them in spring (a common trick: put them in the pump basket). Add winterizing chemicals as needed.

    Cover it

    A quality winter cover keeps out debris, blocks sunlight that fuels algae, and adds a safety layer. Make sure it's secured — Washoe Valley winds are no joke.

    When to call a pro

    Blowing out lines properly requires the right equipment, and it's the step with the highest cost of failure. If you're not confident, this is the one to hand off. A missed line can mean a cracked pipe you don't discover until you open in spring.
