REASONS TO CALL A LEAK DETECTION SPECIALIST:
Some leaks can easily go undetected especially if they are underground or within a concrete deck. A good way to check for underground leaks is by monitoring your water bills. A sharp or drastic spike and fluctuation in the amount of water you typically use is a clear sign of a potential water leak. Another leak detection tip is to keep an eye out for overly saturated areas around the exterior of the property where a landscaping leak may have developed. Through our years of leak detection services here in the Metroplex, we've seen it all and have been able to locate all types of leaks in all types of situations.
- "THE BUCKET TEST" One of the ways to determine if your pool has a leak is to perform whats called a "Bucket Test".
1) A bucket, perferable a 3-5 gal bucket is used to measure evaporation. Fill the bucket with pool water so that the level of the pool and the inside water level of the bucket are the same.
Note: A rock or weight should be used to keep the bucket upright in case of wind etc. Leave the bucket on the seat or step of the pool
2) Turn the pool off with the power switch so the motor does not run for 24 hours. Be consistant with your test - start time: check the level 24 hours after. The pool and the bucket should be even.
3) If there is a pool with a spa - the spa returns should be shut off so the pool does not fill the spa with water. This test is just for the pool - if the spa is an elevated spa and the water level does not change that should indicate the spa is not leaking. If the spa is at the same level as the spa then the spa and pool will go down at the same level. More testing is needed - call a leak detection specialist.
4) The average loss of water per day is 1/8", due to evaporation, approximately 3.75 inches per month. Based on a 600 square foot perimeter pool, losing .078 gallons or 1/8" per square foot, normal evaporation would total approximately 1,400 gallons per month. It would take two hours and 20 minutes, twice a month, to add 1,400 gallons of water using a garden hose (based upon a hose pressure of 50 psi delivering 5 gallons of water per minute). Naturally this loss and fill rate will vary with heat, humidity, wind and rain.
Keep in mind that if replacing water in the pool becomes excessive, this is a sign that a leak detection is necessary.
Note: A typical pool losing an 1" per day, based on 600 square foot (not to be confused with the pools capacity), totals approximately 11,232 gallons per month, about 10,000 gallons over the natural evaporation rate. Based upon your usage and penalty rates, the water bill may increase $100.00 - $1,000.00 per month.
The calculation for water evaporation based on 1 square foot of water 1/8" deep = .078 gallons.
20’ X 30’ Pool = 600 sq.ft. X .078 gal. (gal./sq.ft.1/8"deep) = 46.8 gal.
Calculation to measure Evaporation Rate:
L ength X W idth X .078 gallons (1 Square Foot 1/8" deep) X
(Measured amount of water loss in 8’s) (Ex: ½" = 4; Ex: 1" equals 8)
Multiply this amount by the number of days in the month. This number will conclude a loss due to evaporation or excess water loss.
