As pool season comes to an end, many homeowners focus on installing a winter cover and balancing their pool water. While those steps are important, one of the most critical parts of closing a pool is protecting the equipment that keeps it running.
Your pool pump, filter, heater, plumbing, and other equipment can all suffer serious damage if they’re not properly winterized before freezing temperatures arrive. Even a small amount of water left inside a pipe or pump can freeze, expand, and crack expensive components.
In this guide, we’ll explain how to winterize your pool equipment, the most common mistakes homeowners make, and when it’s best to call a professional.
Why Winterizing Pool Equipment Is So Important
Pool equipment is designed to move and filter water not withstand freezing water trapped inside it.
When temperatures drop below freezing, any remaining water inside pumps, filters, heaters, or plumbing expands. This expansion can crack housings, split pipes, damage valves, and lead to expensive repairs when you open your pool in spring.
Proper winterization helps:
- Prevent freeze damage
- Extend equipment life
- Reduce spring repair costs
- Improve your next pool opening
- Protect your investment
Equipment That Needs Winter Protection
During a professional pool closing, several components should be inspected and winterized, including:
- Pool pump
- Pool filter
- Pool heater
- Salt chlorinator (if installed)
- Plumbing lines
- Multiport valve
- Chlorinator or chemical feeder
- Booster pumps
- Water features and fountains
- Pressure gauges and drain plugs
Each piece of equipment requires slightly different preparation before winter.
How to Winterize Your Pool Pump
The pool pump is one of the most expensive pieces of equipment on your pool system.
Steps include:
- Turn off electrical power.
- Remove drain plugs.
- Drain all water from the housing.
- Empty the pump basket.
- Clean out debris.
- Store drain plugs safely for spring.
Leaving water inside the pump can result in cracked housings and damaged seals.
How to Winterize Your Pool Filter
Whether you have a sand, cartridge, or DE filter, it should be completely drained before winter.
General recommendations include:
- Remove drain plugs.
- Release internal pressure.
- Clean the filter according to the manufacturer’s instructions.
- Leave valves in the proper winter position.
A clean filter is also easier to restart during spring opening.
Protecting Your Pool Heater
Pool heaters contain narrow water passages that are particularly vulnerable to freeze damage.
Before winter:
- Shut off power and gas supply (if applicable).
- Drain all internal water.
- Disconnect unions if recommended by the manufacturer.
- Inspect for corrosion or leaks.
Ignoring the heater during winterization can result in costly repairs or premature replacement.
Don’t Forget the Plumbing Lines
One of the most important steps in winterizing a pool is removing water from the plumbing.
Professionals typically use a high-powered air blower to clear water from:
- Skimmer lines
- Return lines
- Main drain lines (where applicable)
- Cleaner lines
- Water feature plumbing
After the lines are cleared, winter plugs are installed to help keep water out during the winter months.
Winterizing Saltwater Pool Equipment
Saltwater pools require a few additional considerations.
Before winter:
- Turn off the salt chlorinator.
- Clean the salt cell if needed.
- Store the cell according to the manufacturer’s recommendations (if applicable).
- Inspect electrical connections.
Proper care helps extend the life of your salt system.
Common Winterization Mistakes
Many homeowners unintentionally damage equipment by making simple mistakes, including:
Leaving Water Inside Equipment
Even a small amount of trapped water can freeze and crack expensive components.
Forgetting Drain Plugs
Drain plugs should be removed during winter and stored somewhere safe for reinstallation in spring.
Skipping Equipment Inspections
Small leaks, worn seals, or loose fittings are much easier to repair before winter than after freeze damage occurs.
Waiting Too Long
Don’t wait until freezing temperatures arrive. Schedule your pool closing while conditions are still suitable for proper winterization.
When Should You Hire a Professional?
Some experienced pool owners are comfortable winterizing their equipment.
However, professional service is often the better choice if:
- You’re a first-time pool owner.
- Your pool has a heater or automation system.
- You own a saltwater pool.
- You don’t have equipment to blow out plumbing lines.
- You’re unsure whether everything has been properly drained.
Professional winterization helps reduce the risk of expensive spring repairs.
