Water Leak Detection

How to Detect a Swimming Pool Leak: 4 Steps Explained

It’s natural for swimming pools to lose a certain amount of water due to evaporation. Some water may also be lost due to backwashing the filter and splash out. However, if you need to add over 2 inches of water routinely to your swimming pool every week, there may be a leak.

If you suspect a water leak in your swimming pool, here are the steps you can follow to locate it.

Step 1: Check for Common Indications of a Leak

At first, check for the obvious indications of a leak. Below are some common problems that may indicate a water leak in a swimming pool.

  • Does the equipment pad have any leaks? Observe closely the pipe valves, heater, pump, and filter.

 

  • Does the pool have any wet areas surrounding it? Check out if the ground has any moisture. Walk around your swimming pool and in the area around the equipment. Check if there is any wet soil and eroding or sunken areas.

 

  • If you own a vinyl liner swimming pool, check for separations or tears around all the corners, steps, lights, cleaner line, returns, skimmers, and fittings.

 

Step 2: For Confirming a Water Leak, Apply One of the Following Ways to Double-Check

If you think your swimming pool might be leaking, you can check using several ways.

  • Mark the pool’s water level at the skimmer. You can mark the level of water using a grease pencil or a small piece of tape. Check the mark after 24 hours. No more than 0.6 cm (1/4 inch) of water should be lost from the pool per day. If any more water is lost, there may be a leak.

 

  • Fill a bucket with pool water and place it over a pool step. Mark the level of water on the outside as well as inside of the bucket. Ensure that the water level inside the bucket is the same as the water level of the pool outside the bucket. Check the mark after 24 hours. If the drop is greater in the line at the bucket’s outside, there may be a leak. You should conduct this test first by keeping the pump on, and then by keeping it off.

 

Step 3: Determine the Leak Location

If you find that water is being lost from your pool, switch off your filtration system and then observe where the water drop stops. Vinyl Liner swimming pools should contain water at all times. This test should be stopped if you own a vinyl liner swimming pool and the level of water is rapidly dropping. Start adding water as well as call a swimming pool professional.

  • If you find the water stopping at the skimmer opening’s bottom portion, there is probably a leak in the filtration system (that includes the pipes) or skimmer. If you think the filtration system might have a leak, do the following:

 

  • At first, check for the appearance of air bubbles in water in return line when pump of the pool is running. If you find air bubbles, the filtration system’s suction side has a leak.
  • Make sure that the lid of the pump basket is on tight. Also ensure that lid o-ring has a good condition and is lubed.

 

  • If you find the water stopping at the light, there may be a leak at light housing.
  • If you find the water dropping below the light, a leak may be there in drain at the pool’s bottom.
  • If the pool loses greater water when the pump runs, the water leak may be on the system’s return line side. In such a case, check if the backwash or waste line has any running water.
  • If you think the liner, light, skimmer might have a leak, observe closely to see anything resembling a tear, gap or crack.

 

Step 4: Use Reagent for pH Indicator Test or Dye Test Solution near Suspected Leak Location

Put some of your reagent for pH indicator test or one or two drops of a dye test solution near the point where you suspect a leak. Carry out this step with the water still and the pump turned off. Check if the dye goes into the tear, gap or crack.
