To prevent potentially dangerous electrical issues, it's imperative that you turn off the power to your pool equipment — such as pumps, motors, filters, heaters, chlorinators, and lighting fixtures. Even if you turn off the power to your pool equipment, it can still be damaged by wind, rain, and debris.
Running your pool pump during a lightning or electrical storm should be avoided as a power surge or nearby lightning strike could damage your pump. However running your pump during is beneficial. The extra filtering will help clean out the impurities rain has introduced into your pool's water.
We recommend that our customers run their pumps rain or shine UNLESS we have an electrical storm. In that case, lightning could strike an outside circuit, which could damage your pump and other equipment. If you're worried about lightening, turn the pump off or shut off the breaker.
A lightning strike can damage your pool's pump, filter and heater. The strike overloads the electrical circuits and can ruin the equipment. You can install surge protectors to prevent lightning from damaging your pool, but that's just another cost that makes pool ownership too expensive.
Answer: It should not matter much. It could help to filter debris and contaminants the rain washes into the pool. However, lightning can be a concern with the filter running.
So shock your pool and keep the pump running.
And if you're wondering if you can shock a pool IN the rain, the answer is yes. Just remember that rainwater adds more contaminants, so it won't be as effective as shocking during dry weather.
Lightning can also travel through any metal wires or bars in concrete walls or flooring." So it sounds plausible that it could happen to you. But according to Aquatic Safety Research Group, "There are no documented reports of fatal lightning strikes at indoor swimming pools. None!
The short answer is 'yes', but there are other considerations. The biggest fear is a direct strike by lightning. When lightning strikes, it often (but not always) hits the tallest thing in the vicinity.
Step 1: Cover That Pool Up
Although it's not recommended for a major storm, you can use a pool cover for lighter sprinklings, or moderate rain that doesn't involve any severe wind to protect your water. Remember, the rain is acidic and is out to get your chlorine.
Shocking your pool isn't necessary, although, it's not a bad idea either. If you get an extremely heavy rain fall, you could shock your pool for good measure. This will help fight off any contaminants that the rain may have brought to your pool.
Give your pool a good shock treatment 1 to 2 days before the storm hits. You can bring the chlorine level up pretty high to prolong the pool being depleted of chlorine.
Do not return to the pool until at least 30 minutes after the last lightning is sighted or thunder heard. Check the radio or online for weather service warnings to make certain all is clear.
Don't forget the 30-30 rule. After you see lightning, start counting to 30. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.
You can get electrocuted in a swimming pool as a result of: (1) faulty electrical wiring to pool equipment such as underwater lights, pumps, filters and vacuums; (2) no GFCI (Ground-Fault Circuit-Interrupters) protections for outlets and circuits; and (3) electrical appliances and extension cords entering the water.
Car accidents increase as well during thunderstorms due to hazardous road conditions. It is clear that closing indoor pools actually puts people at higher risk of being injured by lightning than allowing them to keep swimming.
The National Weather Service, National Lightning Safety Institute and the National Athletic Trainers' Association are three of several groups that recommend evacuation of indoor pools when the threat of lightning exists.
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
Using a corded telephone during a thunderstorm is discouraged because the phone is physically connected by wires to the outside. A cellphone, however, has no such physical connection and the electric current from a nearby lightning strike cannot reach it. It is perfectly safe to use a cellphone during a thunderstorm.
Skim the pool to remove excess debris. Shock the pool and run the filtration system for at least 12 hours. Test and re-balance pool water.
Myth: Rubber tires on a car protect you from lightning by insulating you from the ground. Fact: Most cars are safe from lightning, but it is the metal roof and metal sides that protect you, NOT the rubber tires.
Lightning can travel through plumbing. It is best to avoid all water during a lightning storm. Do not shower, bathe, wash dishes, or wash your hands.
Do NOT bathe, shower, wash dishes, or have any other contact with water during a thunderstorm because lightning can travel through a building's plumbing. Do NOT use your computers, laptops, game systems, washers, dryers, stoves, or anything connected to an electrical outlet.
A loud roar similar to that of a freight train may be heard. An approaching cloud of debris can mark the location of a tornado even if a funnel is not visible. Before a tornado hits, the wind may die down and the air may become very still. This is the calm before the storm.
