The main issue you will run into with heavy rains and storms is water overflow. Your pool can easily become overly full and will need to be drained of some of the water to restore proper chemical balances and to keep everything functioning correctly.

There are several different pumping methods by which you can remove excess water including siphoning, a submersible pump, or rolling out the backwash by way of the filter.

Water Contamination

With harsh storms come high winds and high winds bring outside contaminants into your pool water. The main contaminant you’ll need to worry about is soil and mulch muddying up the water.

As you return the water level to normal, soil can be removed by slow, daily vacuuming and by adding clarifiers and flocculants—these additives help speed up the process of clearing your water of soil particles that can otherwise be difficult to get rid of.

You can find these chemicals through your local pool experts and they are simple to use: pour them into balanced water, run the filter for 24 hours, then backwash. Repeat this process until your water is once again clear.


Debris is another huge issue that can arise with storms. In preparation, always make sure that you securely store any toys or pool accessories that could easily be picked up and carried by high winds.

Any outdoor furniture that has no place to be stored should be strapped down to a stable area. Also make sure that you leave your pool uncovered during a storm—high winds can damage your pool cover either with flying debris or by the wind itself.

After the storm, you obviously will want to clear your pool of any large debris by skimming and vacuuming before you shock the water and begin the process of rebalancing all the chemicals.

Equipment Damage

As far as the actual pool equipment goes, rainfall directly on the pump and filter system isn’t a huge concern, however, you do need to be cautious of potential flooding of your system. If your filter becomes submerged, it is likely that there are parts you will have to replace.

If you can safely remove the pump, it would be best to store it indoors in a dry area. If that is not a possibility and the pump motor does become submerged, it will probably have to be replaced.

You can potentially avoid flooding of your pump if you sandbag the surrounding area and place a tarp over the top.


If your pool does have the tendency to flood easily, then you’ll definitely have to look into getting this fixed as soon as possible. Storm run-off simply has to have a place to go and it cannot be going into your pool.

This can cause myriad of issues with keeping your pool clean and functioning properly. It is best to look into getting drainage systems installed if you have prior knowledge of flooding issues in your area.

As with any other pool issue or questions, please don’t hesitate to give us a call. We’d be more than happy to help out in any way. Before you attempt to resolve any overflow or flooding problems on your own, please consult with your local pool expert first.
