Does Rain Effect Pool Water?

 

The summer time of rain is upon us once again throughout the Suncoast here in Florida.  With many people owning swimming pools, we try to educate our customers about the effects rain has on them.  We are often asked the question, “Does rain effect pool water?”

 

The most common effects are dilution of chemicals and rising water in the pool.  The first issue can be dealt with by adding more chemicals than normal, depending upon the amount of rain in any given week.  Some weeks there may only be several afternoon storms moving through, adding only an inch or so of extra water to the pools.  These have little effect on the chemicals and rising water levels.  Other weeks may prove to be more challenging, with storms dumping several inches of rain or more in some areas.  These are the weeks that prove to be challenging to pool cleaning companies.

 

Due to the fact we are only at a customer’s pool once every week, we may need to add more chemicals than normal to last until we are there again the following week.  These spikes in chemicals may prevent the homeowner from swimming in their pool for more than the normal few hours after we have added them.  Every person is different in their tolerance of chemicals to their skin.  It is always best to stand on the first or second step for a minute or two, to see if the chemical ratio has any adverse effects on the skin.

 

How else does rain effect pool water? The chance of the water overflowing the pool is the second factor to consider when we experience lots of rain.  Each pool is plumbed differently, and some were built with little prevention for rising water levels.  The most effective system is an overflow pipe built into the skimmer when the pool was built.  This pipe leads from the skimmer, under the decking, and up out of the ground on the outside of the pool.  The pipe will normally have a 90 degree elbow with a vent cap, which allows rising water in the pool to seep out of the vent.

 

For pools that do not have this overflow pipe, you may need to have your pool maintenance company show you how to remove excess water.  This may be in the form of a spigot that was added to the plumbing when the pool was built.  If you do not have one, it would be best to have one added so you can run a hose from this spigot and into the storm drain to siphon off the excess pool water.  The only other way is to open the air relief valve on top of the filter tank, which is a much slower method.  The last way is very quick, but will flood the lawn.  This is to remove the filter tank lid and run the pump, allowing the water to flood over the top of the open tank and onto the ground.  This method should only be done while protecting the flow of water from splashing onto the motor.
