Is My Pool Leaking?

November 8, 2023 Ryan Comments Off

A step-by-step guide for homeowners who want to preserve their pool’s integrity
(and also their wallet and peace of mind).

Introduction

A well-maintained pool offers endless enjoyment, relaxation, and fun for you and your family. But potential leaks are a real concern. They lead to higher water bills, increased maintenance costs, and potential structural damage if left untreated.

This guide is your first step to determining if a leak is compromising your in-ground pool. Whether you’re a seasoned pool owner or a newcomer, we’ll take you through a simple step-by-step process to help you determine if your pool is experiencing significant water loss, and what to do about it.

Once you know for sure you have a leak, you can make a better decision about next steps and repairs, so you can preserve the integrity of your pool and enjoy it for years to come.

The Setup

Pool leak detection is part art, part science. As with every good science experiment, we need good measurements. To get good measurements, we need to eliminate every variable we can.

A FEW QUESTIONS TO GET STARTED:

Do you have a spa with a spillover into your pool?

If so, please allow this to run normally.

Do you have any other water features aside from a spa spillover?

If so, please turn them off.

Are you currently running a heater?

Whether it’s solar, propane, electric, or otherwise, please turn off all heaters and allow the pool to cool down for two days before proceeding with the test.

Ready to get your pool science on?

Let’s perform the test.

The Pool Leak Test

The big idea of this test is to mark your water level, wait two days, then measure again and note the difference. If the difference is big enough, you have a leak.

You’ll need just two tools: a pencil and a ruler.

STEP 1:

Fill the pool to the normal level, which is the middle of the skimmer face. Be careful not to overfill the pool, as the highest portions of most pool tile lines are not always water-tight (but don’t worry, that’s normal).

STEP 2:

Turn your pump off for a few minutes to allow the water surface to settle. You’ll need a flat and still water surface to draw an accurate starting line.

STEP 3:

Open your skimmer lid, and use a pencil to mark the current water level on the canister wall. This is your reference point.

STEP 4:

Turn your pump back on and let it run as scheduled. This is day one of your test.

Collecting Your Results

DAYS 1 & 2:

Let the pump run on its usual schedule.

DAY 3 (RESULTS DAY):

Time to measure and see if you’ve experienced significant water loss. Approximately 48 hours should have passed since you made your reference mark in the skimmer canister.

First: Turn your pump off for a few minutes to allow the water surface to settle.

Next: Use a ruler to measure the difference in inches between your pencil mark and the new water level. This represents your total water loss.

Reading Your Results

Normal evaporation for our area on a non-heated pool with no waterfalls or features could be as much as 1/4″ per day.

If your measurement shows a difference of 1/2″ or less, you’re still within the range of “normal” evaporation in Central Florida.

If your measurement of water loss is noticeably more than 1/2″, and your pool isn’t heated and hasn’t had any water features running other than a spa spillover, there’s a good chance you have a leak.

KEEP IN MIND:

 

    • When kids and pets are using your pool, you’ll experience much more water loss than you would with evaporation alone.

    • If it rains on the days you’re running the test, you should start the test over unless it’s really obvious there’s a leak and you’re losing more than 1⁄4″ of water a day.

Next steps

If it’s apparent you have a leak, we’ll find the reason your pool is losing water and give you clear, honest solutions to fix it.
