The below step-by-step guide outlines the basic procedure for opening a pool in spring.
When in doubt, consult your equipment manufacturer or a pool professional for specific directions.
Equipment Reassembly and Prep
1. Remove Cover: Clean and store it until needed.
2. Remove Plugs: Remove expansion plugs ("freeze plugs") from skimmer and wall returns. Store and place next to cover (i.e. in a Ziploc bag). Discard any damaged/rotted plugs.
3. Reassemble Equipment: Reassemble filter, pump and heater. Reinstall all drain plugs. Reinstall the pump and skimmer baskets, pressure
gauges. If your filter is a D.E. or Cartridge type pool filter, make sure that
the center clamp band is tight and properly positioned. (It was probably
removed in the fall to have the filters pulled out and cleaned with a hose, so
make sure it was re-installed correctly before starting pump). Replace any removed fixtures.
4. Prep and Check System: Place filter valve to the filter position and open air bleeder (beneath
pressure gauge, usually). Open all incoming valves (before pump) and all return
side valves (after filter). Lubricate valves and o-rings as needed. Fill pump
basket with water from pool or hose. Replace pump lid tightly. Look for leaks
out of pump. Double check that all valves and pressure relief orifices are
open. Slide valves (push-pull valves) should be in the down position on most DE
filters and in the up position for Pac-Fab sand filters. Multiport valves
should be on the filter position.
5. Refill Pool: Refill the pool to the appropriate level. Water level should be approximately half way between the top and bottom of the skimmer inlet.
6. Start the System: Turn on the power to the pump, keeping a close eye on the pressure gauge of the filter and hand still on the power switch.
pressure rises well above normal range (above 30 psi) turn off the system immediately and contact either your equipment manufacturer or local pool professional.
7. Adjust System: Adjust the valves and returns for proper flow. Follow pilot lighting and test firing
instructions, usually printed on back of front heater door.
8. Safety Inspection: Check for pressure leaks which may resulted in pipes
or equipment blowing apart. Note water level and watch the pool for leakage
during the following few days. Check that all ladders, steps and other safety equipment are secure.
Cleaning and Balancing
It's typical for a pool to have algae after being closed for the winter, depending on how the pool was closed. If no algae is present, you can simply begin balancing the water.
1. Add 1 lb of Swamp Treat per 20,000 gallons.
2. Brush pool.
3. Independent of chlorine level, immediately add liquid or dry chlorinating product for super-chlorination. Use the recommended dosage rate for superchlorination from an EPA registered chlorinating product.
4. Once all the algae has been eliminated, balance water according to the Hamilton Index.
5. To prevent algae and to keep crystal clear water all season long, use No Mor Problems in conjunction with your sanitizer as directed.
