White goods
All white goods need to be removed and stored in a warm environment over the winter so they do not crack. All skimmer baskets, pump baskets, return fittings, and floor drains need to be removed and stored, too. All winterizing plugs and threads need to be greased and used to plug all open lines once the water has been removed. Service pros need to ensure all skimmers, gutter lines, return lines, and main drain lines are plugged. Finally, it is important to make sure the hydrostatic relief valve on the client’s pool is operational.
Filters
All filters need to be cleaned and drained. Sand filters should be thoroughly backwashed and drained. For cartridge filter applications, the filters need to be cleaned and removed. For those clients whose pools are equipped with a diatomaceous earth (DE) filter, the elements need to be removed, cleaned, and inspected for damage so they can be replaced for the next season.
Pumps and valves
All pump room valves need to be opened along with the lid on the pump (if the pool is an above-grade application). However, if the mechanical room is below grade, the valves leading from the pool to the filter should be closed. If the client’s pump and motor will be exposed to weather, it should be disconnected and lubricated before performing seasonal maintenance to the pump so it can be stored indoors. Adding anti-freeze is an additional failsafe to help protect pumps and seals from any residual water left after draining. Cleaning pressure gauges, flowmeters, and thermometers is also good practice.
Electrical and lights
All fuses and open circuit breakers should be disconnected. If the client’s pool is equipped with any underwater niche lights that will be exposed to the elements, they will need to be removed from their niches. Once removed, they should be bagged and lowered to the bottom of the pool.
Heaters
In addition to draining the pool heater, the drain plugs should be greased and stored in the equipment room for the winter. The gas supply, valves, and pilot lights should be turned off by a certified gas technician.
Deck equipment
Deck equipment, hardware, and non-permanent objects such as ladders, rails, and slides should be removed and put in a weather-protected location. In the case of a public pool, guard chairs, starting blocks, drinking fountains, handicapped lifts, portable ramps, clocks, and diving boards should also be removed and stored. Note: Diving boards should be stored indoors and turned upside down to lay them flat to avoid any warping over the off-season.
Public pool operators should remember to turn off the city water supply to restrooms, showers, sinks, and toilets. As part of the closing process, service pros must make sure everything is drained and anti-freeze is added where necessary. All shower heads, drinking fountain handles, open hose bibs, and fill spouts should also be removed.
Deck furniture (residential and commercial) should also be prepared for winter, too.
