Pool Closing Tips

  • Winterize your pool as late as possible in the autumn, but before the first frost – ideally in normal weather conditions this would be before mid-November.
    Clean your pool before closing.
    Keep your pool free of algae and keep a good water quality before closing.  
    Install a net or a cover over the pool in order to reduce the number of leaves in the pool and to preserve the water quality as long as possible. 
    Cut power to pool equipment  (pump, water heater, salt system) at the source (electrical panel)
    If possible, store the pump and the salt system inside (in a heated room or a location that does not go below freezing
    Clean your pool equipment before storing for the winter (ladder, steps, lights) 
    Block entry to the pool so that no one has access.
    Keep an eye on your pool over the winter and mention any odd occurrences to your specialist at Piscines et Spas POSEIDON (for example a plug that has come loose, a bulge in the liner, a problem with the pool cover, a problem with the pool wall, substantial water loss, etc.)
    Never break ice that has formed on the pool
    Never walk on the pool during winter
    In the spring, once the ice in the pool has melted, proceed with opening the pool

Closing for in-ground or semi-in-ground pools

It is of great importance to properly close an in-ground or semi-in-ground pool in order to preserve its lifespan and also to avoid damage to the filtration system, the structure and the liner. It should be noted that you should never stop the pump before closing, however, it is possible to set the thermostat to the lowest setting or turn off the heater.  Important: Manufacturer’s recommendations always take precedence over any other advice in order to not void the warranty.

Closing above-ground pools

It is also very important to properly close an above ground pool for all the same reasons mentioned in the section regarding in-ground pools.  That said, above-ground pools have one particular issue: it is essential that you ensure the water level is sufficient to preserve the pool’s structural integrity.  It is imperative to preserve the fragile equilibrium between the pressure exerted by the water and the tension created by the structure.

Pool closing service (in details)

 

First, we start by lowering the water level with a pump until the water is 6 inches below the water return jets.  The water will be emptied directly into the road without passing through the filtration system.

Then we dismantle equipment and accessories around the pool.  This includes the diving board and base (if possible), the ladder with anchoring bolts, the jets, the skimmer check valve, the skimmer basket, the floating weir, lane lines, and toys.

Next we store the light bulbs and put the lenses into a plastic bag.  For underwater lights, we take them out and put them into a plastic bag for winter protection.

Pipes are disconnected to facilitate blowing out the filtration system.

The pump is disconnected from the electrical supply so we can remove the 2 plugs and blow air through the pump to completely purge any remaining water.

Now we winterize the filter:

A) Sand filter: remove the plug, remove the pressure gauge and leave the filter in “winterize” mode

B) Cartridge filter: remove the cartridges, remove the plug, purge remaining water, reassemble everything and remove the pressure gauge

Next we will winterize the skimmer: blow out the skimmer water lines to purge them completely, insert a plug into the skimmer so water cannot enter the pipe leading to the pump, insert an expansion foam or gizmo. If the skimmer connects to the main drain, we add a ½ gallon of anti-freeze into the main drain and insert an expansion foam.  Finally we put the cover into a plastic bag.

This is followed by winterizing the pipes. We blow out the pipes to remove all remaining water. Then we insert plugs into the jets so that water cannot re-enter the pipes. If possible, for an above ground pool we will store the pipes instead of blowing them out.

Next we store all the pieces of the filtration system in a mesh bag so nothing is lost for next spring.

Then we add closing chemicals to the pool: liquid and powder winterizing chemicals.

For a small fee, we can add extra winterization options:

  1. Winter pool cover: Install the winter pool cover and fix it in place with cord and pegs.
  2. Cartridge filter: Bring cartridges to office to perform deep cleaning (degreaser and acid) then return to client
  3. Thermopump water heater: Turn the system off, blow out the inside of the thermopump, remove the drain plug (if required) and install protective cover, cut power.
  4. Electric water heater: Turn the system off, blow out the inside of the electric water heater, remove the drain plug and install protective cover or plastic bag, cut power
  5. Solar water heater: Turn the system off, blow out the pipes inside the solar water heater (pipes and panel). To ensure the panels are completely purged, blow air in both the supply and return directions, cut power.
  6. Gas water heater: Turn the system off, blow out the pipes in the gas water heater, remove the drain plug, remove pressure gauge, cut power (if possible), close the gas valve  
  7. Spa overflow: Empty the spa, remove and store jets, blow out the filtration system to completely purge it, insert plugs in the suction holes and in the jets, add the fiber glass protective cover (if available) or add sacks of rocks in the bottom of the spa, place 2 plywood sheets over the spa and place a protective cover over the top.
  8. Salt system : Unplug the cell, clean the cell with a product specially designed for cleaning salt system cells, add an anti-metal anti-mineral product to the pool, store the salt system (if possible), cut power
  9. Removable steps : Remove the weights inside the steps, remove the steps from the water and place in storage
  10. Slide : Remove slide and place in storage (if possible), blow out the pipes of the slide, plug the pipe
  11. All of this will be quickly performed by professionals who insure your pool will stay in good condition year after year.  This assures you of a worry-free winter!
