You may want to tackle this job yourself, typically start the pool opening process in mid-April.
Steps to Opening
Your Swimming Pool
q 1. Drain Pool Cover: Chlorinate water on top of your cover by throwing in shock or
powdered chlorine (5 – 8 lbs.). Then drain this water under the cover and into the pool. If your cover is mesh, this step can be skipped. Peroxide pools should use Peroxide Clarifier instead of chlorine.
q 2. Remove and Clean Pool Cover: Using a leaf net, clean cover of large debris such as
leaves, sticks, etc. Take off all weights and straps that held cover on for winter, except for one end. Water bags should be drained, cleaned and folded for summer. Pull cover off towards the end which is still held down. For above ground pools, you don't need to keep one end tied down. Once cover is off, clean it with Cover Cleaner. Store cover for summer in a clean, dry place. Organize pool storage area if needed. Pillows in pool, if used, should be removed. Service crew should bring in water sample for analysis at this point, so balancing of water is done ASAP. Use coolers to keep sample fresh and label all samples with customer’s name, size and type of pool, phone #, address, etc.
q 3. Clean Tile & Coping: Scrub tile and coping with Tile Line Cleaner.
q 4. Fill Pool: Water level in pool may be low. Fill pool to proper level. When filling above
ground pools, connect filter system first
q 5. Remove Plugs & Gizzmos: Remove all plugs & gizzmos and replace with proper
directional flows, grates or skimmer basket. Remove skimmer ice plate, if used, on above ground pools. Store all goods in one bag for ease of locating in the fall.
q 6. Heaters: Uncover heater & replace all plugs and copper line at pressure switch. After filter is running and pool is clear, turn gas on at all gas valves.
Notes : Should you smell strong gas odors, shut down immediately and call the gas company. If burner tray was removed for the winter, it should be reinstalled by a licensed individual. Call us for details.
q 7. Reconnect Filter System: Reconnect all filter equipment including filter, motor, heater,
ozonator and chlorinator. At this point, you should check to be sure all electrical is
turned on. Do not set time clock until pool is clear and job is completed; then set for 6
on, 6 off cycle separated twice daily. Label plumbing with a paint pen.
q 8. Start System: Prime and start filter system. Be sure that everything is operating
correctly and no leaks are present. If needed, add fresh D.E. to filter. Backwash sand filters and be sure cartridges in Cartridge Filters are cleaned. Light pilot in heater and check operation. Turn burners off after system check. Very important to check heater operation early so repairs, if needed, can be scheduled. Let filters run 24 hours until pool is clean. Do not leave heater running until you have been notified to do so by the customer. Chlorine generators (salt units), do not turn on until the water is 69 degrees.
q 9. Balance Chemicals: Chlorine type pools should be shocked with powdered or liquid
chlorine and the pH should be adjusted. Add sticks or pucks to the skimmer or fill
chlorinator. Pool will not clear unless chlorine level is high, pH is in proper range
and filter is clean. Peroxide pools should add initial dosages of Peroxide algaecide,
clarifier and bactericide. Once you are sure that this is done, bring your water into
Gregorio’s to have a water balance test done. This will guarantee that your pool is balanced for the coming season. Always pre-dissolve all powder chemicals to keep from staining the surface. Again, it is very important to check filter operation regularly to insure that it is running strong.
q 10. Re-Install Liner in Receptor: If vinyl liner has been pulled out of receptor, then
re-install with a clothespin. Use liner lock if needed. Hot water can help in this
procedure.
q 11. Re-install board, ladders, handrails, lights (verify that the light works), slides, solar
blankets & reels, safety ropes and any other accessories or equipment. Solar blanket
should be left off until pool is clear.
q 12. Vac Pool: Vac pool bottom. You may have to use a leaf net to remove large amounts
of debris. Vac pool until it is spotless.
q 13. Final Check: All winter equipment should be stored in one area for the summer.
Closing Your Swimming Pool
1. Balance the pool water:
Have a computerized water analysis done to completely balance the water. Adjust total alkalinity, pH, calcium hardness and stabilizer. Remember a properly balanced pool is less damaging in the winter and easier to clean come springtime. Always pre-dissolve chemicals to keep from staining the surface.
2. Vacuum the pool:
For In-ground Pools:
You may vacuum the pool to waste or backwash till water level is one inch (1”) below the skimmer. This is basically where the water level is left for the winter. If the customer has potential floating liner problems or vinyl lined walk in steps, or a high water table, do not drain below lines or skimmer. Just vacuum the pool as normal.
For Concrete Pools or Pools with Cantilever Coping:
Drain water to 10”-15” below coping. This is to protect tile and coping from winter freeze damage. (See service technician if you have any questions.)
For Above Ground Pools:
Water level should be just below the skimmer.
3. Remove directional flow, grates, jet fittings, and skimmer baskets.
Flush clean and store in bag for the ease of locating in the spring. Organize the pool storage area, if needed. Clean the waterline with Tile Line Cleaner
4. Backwash, clean and drain filter:
Sand filters: Backwash, then go to rinse, then to filter and if necessary, add filter
cleaner following direction. Take drain plug out of bottom of filter, leave drain plug out, open air relief valve and store plugs in motor basket for winter.
Diatomaceous Earth Filters: Disassemble filter, marking where bump handle (if applicable) lines up on filter tank. Flush elements and tank. Be sure tank is empty. Clean filter elements with Filter Cleaner. Flush out thoroughly and __ put back together. Store filter in a dry area.
Cartridge Filter: Take apart, flush out and clean cartridge with Filter Cleaner.
and store.
Never store a dirty filter, since deposits and scale may harden and cake over the winter – leaving you a tough repair or clean-up job in the spring.
For Diatomaceous Earth Filters and Cartridge Filters, it is a good idea to have filters cleaned professionally at least every other year.
5. Drain Motor by turning upside down or removing plugs.
Store motor in warm, dry area for winter. Grease all drain plugs and threaded holes and ball valves. Lubricate, grease, vaseline: nuts, bolts, o-rings, washers and gaskets. If filter or motor is stored outside for the winter, cover it with plastic and tie down. (Be sure to leave all drain plugs out of sandfilters.) Add antifreeze to motor unit until antifreeze _ comes out of all plug areas. Replug.
6. Blow out lines from filter to pool.
Return lines and low suction lines – Using vacuum cleaner on exhaust or a blower, blow out lines till you can see all the water has cleared itself from the pipe and only air is left coming out. Quickly plug fitting tightly using a #9 plug. Add antifreeze to filter area (1 gallon per line) and then cover pipe opening with plastic or the like.
Skimmer lines – Blow water back into pool and sponge out skimmer to
be sure no water is left in pipe. Add antifreeze to pipe. Install tall gizzmo into skimmer and add 4” of antifreeze around gizzmo. Once again, cover pipe with plastic. If water level is not drained below skimmer, blow out the same way as return lines only using gizzmo instead of plug. Add antifreeze to water around gizzmo.
For Above Ground Pools – Use smaller gizzmo and, if possible, just remove hoses from return fitting and bottom of skimmer and store for the winter. This would make it unnecessary to blow out the lines. An Above Ground skimmer plate should be used on the face of the skimmer.
Bottom returns or Main Drain – Add as much antifreeze as possible to pipe and cover with plastic. Other procedures can be followed. Please contact service technician for more details.
7. Pool Heaters:
Turn off three (3) gas valves:
1) silcock near outside of heater;
2) pilot turned off;
3) valve at gas tank also closed.
Remove or open all drain plugs and allow water to drain out. Vaseline all plugs and fittings. Add antifreeze until it runs out of drain plugs and then re-close drain plugs. Unthread inside copper line at pressure switch and leave unattached for the winter. Wrap the top, only, of the heater in plastic being sure to cover all openings. This will keep out __ any rain, debris and rodents. Cover with plywood if necessary. Turn off power, if _____________ applicable.
Note: If wanted, burner trays can be removed for winter, however, the State of
8. Chlorinators: Should be drained and flushed out. If pool has an ozonator, it should be
disconnected and stored in a warm, dry area.
9. Remove
Ladders, diving board and handrails. Rinse with clear water and store diving boards flat or sideways on a 2x4 off the ground. Lubricate all exposed nut and bolt areas, especially ladder anchors. Slides are left outside with tubing drained out.
10. Skim Pool:
Store summer goods (pole, vac hose, skimmers and all pool accessories in one area.) Be sure vac hoses are empty and clean. Automatic cleaners should also be stored for the winter. Always remember to store cleaner hose in straight lengths. Never roll them up.
11. Pool Lights:
Remove and secure on pool bottom unless the light is 50% lower than the coping. Example: most vinyl liner pools, the lights stay in for the winter; most gunite pools, the light must be removed by dropping the light to the bottom.
12. Solar Blankets: Clean with “Cover Cleaner. Dry, fold and store in a warm dry place.
13. Pool water:
For Chlorine type pools – Add winter shock and winter algaecide. Follow instructions on back of containers for proper amounts. Example: Above ground pools generally take one (1) winterkit, 16x32 is the same, 18 x36 takes one (1) winterkit plus misc.
For Peroxide pools- add one quart of Peroxide algaecide per 25,000 gallons, one gallon of Clarifier per 10,000 gallons and bring Peroxide bacteriacide to 50ppm.
It is a good idea to circulate the water in the pool with your motor if possible. If
not possible, then be sure to spread the chemicals evenly around the entire pool.
If no cover is used, increase the chemicals used.
14. Install cover onto swimming pool:
Above Ground Pools: Inflate “Ice Expansion Pillow” (or pillows) with air pump or vacuum cleaner. Do not overfill. Secure pillow in center of the pool using nylon cords or fishing line. Do not draw cords tight. Allow slack for pillow to rise and fall as the water freezes and melts. The purpose of the bubble is to absorb ice expansion. Instead of the water freezing and pushing outwards on the wall, it will
push on the pillow, which helps absorb this pressure. Be sure not to use too many pillows since it will take up some of the slack. Check top cap connectors for rough or sharp edges that may damage the cover. Cover any sharp areas before putting on the cover. Drape your pool cover over the pool and pillow(s), allowing it to float on the water. Pull the cover slack down the sides of the pool. The principal is that the snow and weight will pull the slack out of your cover, so the more slack the better. Secure the cover cable around the pool but do not string cable behind or through pool uprights. It should sit outside of the pool structure to allow for movement. Milk jugs are sometimes used to help hold cover in place, but this is not recommended unless you are in an extremely windy area.
Note: During winter, if the snow load gets to be too much and removal of such is not possible then the best alternative is to loosen the cover cable and release the tension on the pool and the cover. This procedure, however, is only used as a last resort.
In-Ground Pools: Install the cover trying for 2 feet (plus) overlap. Be sure cover is neat, secure and tied down where deemed necessary. Water bags should be ¾ full and pulled tight together. If walk-in steps are present, please add a 4’x8’ sheet of weatherized plywood before putting cover down. Never use blocks or heavy articles to hold down cover since they could end up being pulled into the pool.
Note: It is important to pump or siphon off the cover as water builds up on it during the fall and spring. Add an adequate amount of powdered (5-8lbs.) or liquid chlorine to the water on top of your cover and pump the water back into your pool.
Peroxide pools: Use Peroxide Clarifier instead of chlorine.
Gunite/concrete pools, fiberglass or vinyl pools with cantilever coping,: Keep the water level the same as when it was closed (10”-15” +/- below coping). If you have a mesh cover it may be necessary to drain the water down slightly as opposed to pumping it under the cover in order to achieve the proper water level. Vinyl pools with vinyl steps, it is preferred to keep the top step slightly covered by the water level. In all cases, try to keep the water level close to where it was when closing the pool.
15.Disconnect all fuses:
Switches and circuit breakers should be turned off. Time clocks should be off with tongs disconnected. Mark down the settings. All gates should be closed to prevent intrusions.
Final Check: Clean pool house and equipment area.Filter pump and equipment must be
stored in a dry environment. NEVER are they to be left outside!
16. Fill out completion sheet and leave Questionnaire. Put yellow service sticker on equipment.
17. Note: If additional repairs are necessary please make a note of this on paper work. Please notify homeowner that the repairs will be billed separately & get approval for them.
