It’s springtime in Southeast Texas, which means rain — lots of it. This past week saw the area deluged by storms, causing flooding and destruction all over the Houston area. Along with the flooding of highways, yards and houses, the recent weather has caused area pools to be filled with rainwater and debris, both floating and wind-blown.
When we redesigned this website a year ago, we did a series on the effects of rain when it comes to building your pool. This rainstorm has prompted us to pen this writeup on how to clean and get your pool back in swim mode after heavy storms and flooding.
Three variables in cleaning your pool after flooding or a storm
The rain had let up a bit but seems to have come back with a vengeance. It will stop eventually at some point. When it does, it’ll be time to look in your backyard to see how the pool is holding up. While your pool might not look quite like the picture above, odds are that there are a lot of displaced items in it. Whether it’s animals that have decided to take residence in your pool, dirt or leaves that were blown in, or simply an overflow of displaced rain or groundwater, your pool isn’t exactly swimmable right now.
It’s not a simple as taking a skimmer and scooping out the foreign debris, though. Here are the three things you have to be cognizant of while getting your pool back in shape.
Before starting the process of cleaning your pool, it’s important to take the appropriate safety measures. When it comes to flooding, that means making sure any animals or debris such as broken glass or branches are identified and removed safely and completely.
We know what you’re thinking — what kind of animals could possibly be in my pool? Well, the recent flooding saw a baby tiger get loose in Conroe. While we don’t expect any big cats to make an appearance in your backyard, don’t be surprised if snakes, bugs or small mammals — alive or dead — get blown or washed into your pool from the flooding. Spiders can also make an appearance, especially in dark places such as filters and skimmers. That includes poisonous spiders such as the brown recluse, so wear gloves and be careful when sticking your hands inside the filters or skimmers.
As for other animals, the amount of caution depends on the animal. Many bugs and smaller snakes can be removed with minimal risk, but if you get a larger snake, a poisonous snake such as a copperhead, or a sizable dead mammal, you’ll want to have an animal removal service do the trick.
As far as glass and other debris, the advice is the same as with the spiders — be careful and don’t haphazardly stick your hands into hard-to-see dark areas. Have a flashlight handy and be safe.
Once you’ve gotten all potentially hazardous material out of the pool, it’s time to deal with the other annoyances that have blown or washed into the pool. Heavy storms and flooding can introduce all sorts of particulates to the equation, items such as leaves, dirt, mud, sand, and mulch. These elements will overpower your robotic cleaner and clog up your filters, so you have to be careful.
While you’ll be able to grab some of the bigger chunks of debris, others will have to be removed by vacuuming and filtering. To best do this, turn off your pool and let the particulates settle on the surface of your pool before starting the vacuum process. To vacuum your pool, attach the vacuum tube to the filter pump, screw on the vacuum head and turn on the pool, allowing your pump to suck debris from the surface to the filter.
Odds are that you’ll have to do this process a few times, as the filter can only handle so much material before being clogged. Turn off the vacuum, clean the filter, and repeat the above process until the vast majority of the particulates are gone. At that point, your robotic cleaner should work effectively.
In extreme cases of heavy particulates, draining the pool partially is an option. Doing this, then scrubbing the surface, will help prevent algae blooms after a flood. If you decide to drain the pool, do not drain more than half of it and certainly do not drain all of it. If you do the latter, your pool will be dislodged from the ground (which is filled with groundwater that will push the shell of your pool up) and start to float. If this happens, you’ll have to completely rip out your pool and re-do it. And you don’t want that.
Another way to combat algae, or even the staining of your plaster from material such as mulch, is to scrub your pool once a day during the storm. Scrubbing your pool breaks up the material and can save you money down the road, as the chemicals in mulch combined with standard white plaster can cause discoloration and, eventually, the replastering or acid-washing of the surface.
Once you have the debris and particulates removed, it’s time to get your water back in balance. Introducing heavy rain and groundwater will alter the pH and chlorine balance. If you have an IntelliChem then you can set the system to your preferred specs and have the system do its work. We noticed that pools with IntelliChem did a good job of keeping the pool’s water chemistry afloat (pun intended) during the most recent storms.
If you don’t have an IntelliChem, then you’ll need to add chlorine to your pool during the storm to keep the water close to balance. With the excess rain, ground and flood water that’s present, you’ll want to go a little heavier on chlorine than you normally would. Pouring the chlorine while you are brushing the pool is a good way to be efficient with your maintenance time.
