Gathering as much information about and how much water loss there is will assist in determining where the problem is. Depending upon your climate you can determine whether you have evaporation or a leak. This is done by filling a bucket with pool water and putting it on the steps of the pool. Mark the water level in both the bucket and the pool and monitor it for 24 hours. If the loss is the same then it is a good possibility that it is evaporation.
Dry air, warm days and cool nights increases evaporation. Call or email us for questions. npsleakdetection.com 336-971-5809 #poolleak
