The Inspection

Our technicians test all types of systems, from standard single-pump pools to the most elaborate multi-pump backyard water wonderlands. Testing a basic residential pool, including both the structure and the plumbing, costs $350-450. For larger and more elaborate systems, call or email our office for a quote.

By pressure testing each line separately, we can isolate the specific leak. We inpsect the structure both from the surface and underwater using scuba equipment and utilize non-toxic dyes, injected into cracks and holes, to locate structural leaks. Our leak detections have a 30-day guarantee, so if a small secondary leak occurs, we'll come out free of charge to locate that one, too!

How do you know if you've got a leak?

The best way to determine if your pool, spa, or fountain is losing water due to a leak--and not natural evaporation--is to do a bucket test. The following instructions are for a pool but will just as easily work in a spa or a fountain.

Bucket Test

Step 1: Place a 3-5 gallon bucket on the bench or first step of the pool. The water in the pool should reach two-thirds the height of the bucket. Put a stone or large brick in the bucket to hold it down.

Step 2: Fill the bucket to the level of the water in the pool. In other words, the water inside the bucket should be at the same level as the water outside the bucket.

Step 3: With a piece of tape, mark and date the level of the pool water on the side of the bucket.

Step 4: Run the system on its normal timed cycle and check the pool water level after 24 hours.

If the water in the pool and the water in the bucket have decreased but are at an even level, the water loss is from evaporation only. If the pool water level is lower than the bucket water level, the pool is leaking. Maximum evaporation in the hottest part of summer is a quarter inch per day. Anything more than this indicates a leak.

Other Steps You Can Take

If you have a combination pool/spa, isolate the pool and spa by closing the valves between the two and see which one leaks.

Warning: Never let your pool drain to empty. As little as two pounds of ground water pressure can lift a gunite pool out of the ground. We do not recommend that you waste any additional water on a leak by letting your pool drain down. We are able to test any pool or spa at its normal operating level.

We price our leak detections according to the type of system you have. So the price for a basic pool will be less than the price for a pool/spa combo, which will be less than the price for a system with multiple pumps and features, such as fountains or a disappearing edge.

Note: We do not test portable spas.

Why is it important to fix a leak?

Structural Damage

Allowing a leak to go unchecked can lead to permanent damage to your pool or its surrounding decking. As the water leaks out, it can erode the soil, causing voids under the deck or pool as well as deterioration to the reinforcing bar that supports the pool and deck. A simple detection and repair now can save you from costly and extensive repairs down the road.

 

Pump Damage

If a leak goes unchecked and a pool's water drops below the level of the skimmer throat, the pump will run dry. Such overheating will damage the pool's pump.

Extra Cost of Water and Chemicals

So, you've got a leak and you know not to drain the pool because of the potential for structural damage and you know not to let the water drop below the level of the skimmer because of the potential for pump damage. That means you are continually refilling your pool to keep it at normal operating level. And this additional water needs to be treated with more chemicals or salt, depending on your system. The cost of water and treatment can add up... making a leak detection a wise, economical decision.
