    National Pool Opening Day is Here!

    Summer is Coming! National Pool Opening Day

    There's a national holiday for every date on the calendar and for every topic under the sun, but National Pool Opening Day, observed on the last Saturday of April, is a holiday we can all rally around.

    The National Pool Opening Day holiday is meant to awaken pool owners from their water-less slumber, rub the filter sand from their eyes, stand atop the diving board and shout to the family, "Thy pool will be open today - prepare for summer fun!"

    As a pool owner, you know there are a lot of things that goes into opening the pool, and National Pool Opening Day is a great reminder to look at and care for the many moving parts of your pool, to prepare for a happy, safe season of swimming.

    This year we have made it easier for you to find all your pool opening products in one place. Just visit our Pool Opening Shop, where currently sales are running in six categories!

    TEST THE WATER FIRST. Once you peel back the winter cover and see the challenge before you, start by checking your pool chemical levels. A good water test kit with fresh reagents is important for accurate home water analysis. For best results, use the highly regarded Taylor Complete FAS-DPD test kit. You can also use Test Strips, which are less accurate but can be helpful for quick water checks. Like test kit reagents, expired test strips will produce false water test readings. If over two pool seasons old, strips and reagents should be replaced.

    SPP pool chemicals are delivered in only 1-2 days, and in just one day to most parts of the country. We stock the most common pool chemicals (and thousands of other best sellers) in nine warehouses around the U.S. - for super fast one-day delivery, for those lucky enough to live in the yellow zone shown.

    When stocking up for the summer on pool shock and tablets, remember to order water balance chemicals for pH, alkalinity and calcium, and don't forget to check cyanuric acid (stabilizer) levels, and adjust to 25-50 ppm.

    Your pool opening may also need an algaecide and water clarifier to control algae and help your filter remove finer particles from the water. See our Spring Start-Up Kits for complete pool opening chemical packs with shock, clarifier, algaecide and stain preventer.


    POOL CLEANERS have wearable parts, and usually need more frequent repairs than other pool equipment. Inspect closely for the cleaner parts that contact the surface, or debris bags and hose parts that are worn.

    POOL FILTERS, either sand, DE or cartridge will need the filter media replaced at one point. Sand lasts 3-7 years, DE grids about 10 years, and filter cartridges 2-4 years, depending on size and other factors. Extend the life and improve filtration by using a Pool Filter Cleaner before or after spring clean-up.

    POOL PUMPS have electric motors which will fail at some point in time, usually at spring start-up, or at the hottest part of the summer. When your motor trips the breaker or won't turn on, it may be a loose wire, tripped GFCI, blown capacitor, or it could be a fried motor. Loud motors are typically a sign of worn bearings. Pumping problems are different than motor problems, such as air leaking into the pump, a clogged impeller, or low water level.

    POOL HEATERS: If you have a pool heater, the best spring maintenance you can do is clean out the bottom of the unit to remove any leaves, cobwebs, ant hills. Make sure the air vents and drain holes are not blocked in the cabinet. If leaves have collected inside a heat pump, or on top of a gas heater exchanger, remove the heater top to clean them out. If mulch or soils have built up around the edge, break out the shovel and dig it out.

    POOL LADDERS, SLIDE & DIVE have lots of bolts that should be checked for tightness. Especially the step treads, which can loosen over time and lead to injury. Clean any slick substances on pool slides and diving board surfaces and handrails.

    CHLORINATORS are normally easy care items, just the chlorinator lid o-ring needs to be lubed regularly to make a good seal, protect the o-ring from the chlorine, and keep the lid easy to remove. Clean the o-ring and mating surfaces first with a rag to remove dirty grease, and then apply a thin bead of Teflon pool lube evenly to the o-ring and sealing surfaces.


    ABOVE GROUND POOLS: Connect the pipes or hoses from the wall skimmer to the pool filter and then to the pool pump, and back to the pool wall return. Reassemble the pump and filter, and be sure all fittings are tight. Fill the pool of water to the middle of the skimmer and open the filter air bleeder, then open the valves to flood the lines and fill the pump with water. Plug the pump into a grounded electrical outlet, open the suction and return valves, and remove any plugs in the pool skimmer and wall return. If there are any air leaks (into the pump) or water leaks (after the pump), shut down the pump, close the valves and put on your fix-it hat!

    IN GROUND POOLS: Equipment reassembly is a bit more complicated, but it starts the same way, by screwing the drain plugs back into the pump, filter, heater (with Teflon tape!). With the water level raised, winter plugs can be removed from the skimmer and wall returns to flood the lines. Fill the pump with water from a hose or bucket, and seal the pump lid tightly. Open the filter air bleeder, open the suction and return valves, and turn on the pump. Start-Up with a multiport valve on the 'Waste' position. This is a good way to flush out the skimmer and drain, and it has much less resistance as well, good for pumps that have difficulty 'catching prime'.

    National Pool Opening Day is upon us, Saturday, April 28, the last Saturday in April. Make it your annual tradition to join us in welcoming spring by opening your pool!

    If the last Saturday is too soon to open your pool, then join the celebration by getting out there and cleaning off the cover, and closely inspect the pool and pool equipment. If you normally open the pool in May, it's the perfect time to pull back the cover, test the water, and add another quart of algaecide, refill winter floaters, or shock the pool.

    Even if you only stare out your window at your pool and do nothing else, you can still celebrate National Pool Opening Day as the symbolic gateway from a cold, dead winter landscape to splashing fun in the summer sun. And as long as you are just sitting at your computer, help us trend the hashtag #PoolOpeningDay on social media!
