Are Screened In Pools as Prone to Flooding?


In short, the answer is yes. Screened in pools are just as prone to flooding as unsheltered pools. Still, things might not be quite as bad come clean-up time—depending on how catastrophic the event was, of course. That’s because screened in pools can act as a giant filter.

Screened in pools aren’t going to avoid taking on flood water. The amount of debris that gets into the area, however, could be much less if the screens survive the onslaught. Hopefully, you don’t have a huge cleanup to deal with. Either way though, you can get your pool back to sparkling clear with some hard work and perseverance.

We’ve got a ten-step list you can follow to get your pool up and running again as soon as it’s safe to do so.

Assess the extent of the damage

As with any type of recovery effort, the first step is to assess the extent of the damage. Once the storm has passed and it’s safe to go out, you can discover how badly the pool flooded. Check the pool equipment for damage too. Hopefully, the pump, pipe, and filter system survived without sustaining any cracks or other types of damage.

If you haven’t lived in your home long, this is a good time to check to see how drainage runs off your property. Does the natural drainage of your yard flow into the pool area? What about your home’s gutters? If you notice either of these flows toward the pool area, you need to address the problem as soon as possible.

Swab the deck

Once you know exactly what you’re dealing with, it’s time to start the clean up process. Before you dive into the pool itself, thoroughly clean the pool deck. For that matter, you should clean the entire enclosure floor. There’s no sense trying to get the water clean if it’s surrounded by muck. If you don’t clean it all up, all that stuff is eventually going to find a way into the water. It’s due to the law of averages or something of the like.

If you have to wait for the area surrounding the pool to dry up before you can begin, be patient. There are probably branches and yard debris that you can deal with in the meantime.

Break out the brush

If you’ve been meaning to get to the gym and work on those guns, you’re about to make up for lost time. Thoroughly brush your pool before you even start the pump. It’s going to be hard to see what you’re doing, but you’re aiming to stir up every piece of silt and dirt out of their hiding places. After you get things stirred up, set the pool filter to run 24/7. The next step is to brush your pool again. In fact, you may need to keep brushing over the next several days. The more you brush, the faster the filter will complete its job.


Have you ever looked forward to breaking out the vacuum so much? When you’re satisfied with the ever-lightening color of the water, you can put the brush away and move on.

If you have a sand or Diatomaceous Earth (DE) filter, don’t forget to set the multiport valve to the “waste” function. Remember, too, that vacuuming removes water from your pool. Turn on your garden hose and place it in the pool to maintain your water level. Keep your eye on the pool skimmer as you work. If the water drops below the half-way point on your skimmer, take a break and let the pool refill a while before you continue.

The slower that you pace yourself, the more debris you’ll get out of your pool.

Test and balance

After you’ve got most of the sediment cleaned up, you can start testing the water chemicals. Be prepared for readings that are completely out of whack. Start by balancing your pH and Total Alkalinity. Next, check Calcium Hardness and Cyanuric Acid levels. It’s likely going to be a work in progress over a few days to get things leveled up.

We’ll interject here that this can be the case even if you’re dealing with a big rain event and no flooding occurs. That’s because rainwater appears clear, but is full of contaminants and pollutants.

Remove phosphates

You’re past the halfway point of the recovery process! However, the thought of dealing with the chemistry end of things is a bit daunting for some people. No worries though. You can do this!

While phosphates, as a rule, technically aren’t harmful and your water sanitizer usually depletes them before they get out of control, they’re algae’s main food source. After a heavy downpour or worse, a flood, the phosphate level is going to be off the charts. It’s a perfect breeding ground for algae. Test the phosphate level and add phosphate remover. Test the levels again and wait until they’re in check before proceeding to the next step.

Shock it

Your pool should be looking much better by this point in the recovery process. Now, it’s time to throw in some shock and raise the chlorine level. Your chlorine level needs to be at least 30 parts per million (ppm). Typically, that equates to a triple shock or 3 pounds of pool shock per 10,000 gallons of water.

After adding the shock, continue to brush your pool in the morning and the evening. It loosens any remaining debris—you’ll see it after you get the water stirred up. Run your pool filter continuously for the next 72 hours.

Enzyme and clarifier

If your water is still looking a bit murky at this stage of the game, use a water clarifier to eliminate any remaining organic material. If the clarifier doesn’t completely do the trick, purchase a pool flocculant. It’s sure to finish the job, but remember to vacuum your pool again after using it.

Send stains down the drain

Chlorine is going to continuously eat at the stains that all the dirt and debris left behind on your pool walls. You can step up the process though and purchase a “stain away” product at your local pool store.

Clean or replace the filter

It took some doing, but this is the last step in your pool recovery process. After taking your pool from flood to finish, your pool filter has gotten quite a workout. Inspect the filter and filter cartridges for damage or blockage. Flush any remaining ick from your filter and determine if you should replace your filter cartridges.

Odds are, you will decide new cartridges are the best route to take. Even if they could be salvaged, you’ve put in a lot of work! Pop in those new cartridges and kick back poolside for a bit. When the sparkling water becomes just too hard to resist, shout “Cannonball!” and go for it!

We dare you.
