We have had several customers call and tell us recently, "I am losing water weekly in my pool. Can you come and see if I have a leak somewhere?"
People don't always realize that not all water loss is due to leaks. So what I tell customers is to first find out how much water they are losing on a day to day basis. If you are losing more than 3"-4" of water during the winter or summer then, yes, you could possibly have a leak that needs to be addressed quickly.
However, it is important to find out what amount of water is being lost daily and/or weekly because even though we are in the winter months, EVAPORATION does still occur and is still necessary to keep an eye on it.
Normal water loss due to evaporation for the DFW area during the summer months can be between 1/2" to 1" per week typically, which doesn't seem to surprise anyone.
What does surprise people is that water loss due to evaporation in the fall and winter months does still occur at a rate of around 1/4" weekly!!
In fact, water evaporation is much greater in the fall than in the summer, when water temperatures are high and air temperatures are cold (especially at night). This will just suck the water right out of the pool.
Here are some other variables that can create water loss:
- Surface area of the pool
- Relative humidity
- WIND !!
I punctuated "WIND" because many people don't realize it has alot to do with pool water loss year around, not only in the summer or winter.
Many pools are built with an overflow grate in the tiling much like the grates found on pool decks. These overflow grates are designed to get rid of excess water that builds up on decks from splashing, rain etc. The grates in the tiling of a pool are designed for the same thing. They keep the pool at the correct water level and get rid of excess water caused by heavy rain, overfilling, etc.
These overflow grates, however, can work against the pool water level as well. That's why I mentioned the WIND. When it is windy outside, the water in the pool can have waves which push the water right out through the grates. The end result of this is a drop in the pool water level and panic.
So if you have noticed water loss and are concerned that it may be due to something other than evaporation or wind, give us a call so we can set up a time to come out and look at it!
