Commercial Swimming Pool Closing

A properly closed pool is easier (and cheaper) to reopen in the spring. When winter prep is skipped or done incorrectly, openings can quickly turn into bigger issues—imbalanced water chemistry, dirty filters, or equipment problems like pumps and heaters. Our Certified Service Technicians follow proven, industry best practices to close your commercial pool the right way, helping protect your facility through the off-season.

How we’ll close your commercial pool

• Remove debris from the pool

• Lower the water level (if necessary)

• Test and adjust water chemistry

• Remove handrails and ladders

• Remove pool lights (as applicable)

• Raise deck anchors for the safety cover

• Replace damaged return plates (as needed)

• Blow out plumbing lines and add non-toxic antifreeze

• Install winter plugs

• Remove plugs from equipment and store them in the pump basket

• Remove pins from timers or disable the automation controller

• Empty the erosion feeder and leave chlorine pucks out to dry near the equipment

• Add closing chemicals

• Remove ORP and pH probes, store sealed in salt solution

• Shut off power to automation, pumps, heaters, lights, and related equipment

• Install the winter cover; replace worn buckles/springs, and extract/replace damaged brass anchors

• Provide spring repair recommendations and cost-saving tips

Ways to reduce closing labor costs

These items can help speed up your closing appointment. We include this guidance for maintenance program customers:

• Raise free chlorine to 5–10 ppm

• Adjust pH to 7.2–7.8

• Adjust total alkalinity to 80–120 ppm

• Lower water below equalizers; draining hot tubs ahead of time can reduce labor (as applicable)

• Unlock gates/doors to the pool and equipment areas

• Provide access to a powered electrical outlet near the work area
