Taking Care of Your Pool After a Storm

Whether it’s heavy rain, excessive winds, or a power outage, your swimming pool needs some special attention. Taking care of your pool after a storm is important. So, let’s look at how rain, wind, and power outages affect your backyard paradise and how to correct things.

The Problem With Rainwater

Rainwater is acidic, and that can affect your pool’s water chemistry. The negative affects might include:

pH balance
alkalinity levels
calcium hardness
your pool’s cleanliness by throwing debris into the pool (if so, do be sure and vacuum and brush the walls)

While rain from the sky can affect your pool chemistry, there are other issues. When you have run off from a chemically treated pool deck or even your roof, that can cause problems with your water chemistry. Or, you may have problems from runoff from your chemically treated yard.

You also may end up with extra leaves, dirt, and debris in your pool, causing staining and other problems.

It is worth noting that light rains don’t usually pose a problem, while heavy, long-lasting rains cause a lot more issues.

How to Deal with Heavy Rains

The most important thing you can do at all times is test your water chemistry. Test it on a weekly basis for great results. If you do this, you are already well ahead of problems when the rain pours down.

If you know heavy rain is coming, you might also add some algaecide to preempt any algae issues.

In addition, take the following steps after a heavy storm:

Skim the leaves and debris out of your swimming pool
Clean out your skimmer baskets and pump basket
Check your electrical equipment and turn it back on
Clean and backwash your pool filter
Check your water level and remove excess water if necessary
Vacuum and brush pool walls and pool floor
Shock and balance your pool :
- pH: 7.4-7.6
- Total Alkalinity: 80-120 ppm
- Calcium Hardness: 180-200 ppm
Run your filtration systems and circulate your pool

For Overly Full Pools

Always drain excess rainwater from your pool so it’s at a proper level for skimming. Remember – don’t drain below the skimmer, or you’ll have problems with your pump.

It’s also helpful to drain the excess water if your pool is near the entrance to your home so you don’t get any pool overflow in your home or basement.

Here are two solutions, depending on your pool:

If you have a cartridge filter, think about installing an outlet valve so you can pump your water to the most appropriate skimmer level.
If you have a sand filter or D.E. filter with a multi-port valve, change it to waste mode. This gets rid of extra water and avoids running it through your filter.
