The extra filtering will help clean out the impurities rain has introduced into your pool's water. Pool pumps are made to withstand rain and it is beneficial to run your pump during or after rain.
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.
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.
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.
Chemicals that you add to your pool while the water is circulating don't need to be recirculated; they will stay mixed even if you don't pump the water continually. Although it's generally recommended that all the pool water undergo filtration every 24 hours, the pump does not need to run all the time.
Protect the pump motor from water damage
In addition to removing circuit breakers, consider moving the motor indoors or covering it with a waterproof material to prevent water from getting inside.
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.
Heavy rains will dilute your pool alkalinity level, causing it to fall by 5-10 ppm a day. Low Alkalinity and low pH levels in pools can create a corrosive water environment. Corrosive pool water can result in the damage of underwater metal surfaces, such as pool lights, ladders and rails.
The Department of Environmental Health recommends avoiding activities such as swimming, surfing, and diving for 72 hours after it rains. Research has shown that the risk of infection is the highest during and the day after rain, and declines to around normal levels after three days.
Effect on Pool Water pH
Since rain is diluting your pool, you may expect that it will reduce the acidity of your pool water. However, all rain in the US is acidic due to pollution, so rain actually decreases your pool's pH – in other words, the pool water becomes more acidic.
It's best to run your pool pump during the day
Not only does sunlight give fuel for algae to grow, it also destroys your pool chlorine and this is why you should always run your pool during the day!
The rule of thumb is generally 8 hours, although it could be anywhere from 6-12 hours, depending on your pool's size. Each pool is unique, so to keep your pool pump efficient and effective, you need to figure out exactly what your pool's turnover rate is.
One of the most significant consumers of energy in homes with swimming pools are pool pumps, which keep pools clean by circulating water through filters. Pool pumps can consume 3,000 to over 5,000 kWh per year.
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.
After it rains, you should remove standing water as soon as possible. To do this, you'll want to use a siphon or a water pump. An automatic pool cover pump is one of the most useful pool supplies in New Haven County, CT because it can remove standing water from your cover without you needing to do the work.
