How to Spot and Fix a Pool Leak Before It Costs You

Have you noticed your pool water dropping faster than usual? Or maybe your lawn has mysterious soggy patches that never dry? Pool leaks can sneak up on homeowners, quietly wasting water and money until the damage becomes impossible to ignore.

At Royal Pool & Spa, we’ve seen how leaks can affect more than just your pool — they can harm your yard, foundation, and finances. Here’s how to tell if your pool might be leaking and when to call in the experts.


1. Persistent Wet Spots in Your Yard

Because most pool plumbing runs underground, a plumbing leak can show up as areas of grass that stay damp long after it rains.

Common causes include:

  • Shifting soil or ground movement
  • Freezing and thawing cycles
  • Tree root intrusion
  • Pool deck settling

When pipes crack or shift, water escapes and saturates the soil. In some cases, finding the exact leak may require excavation, so it’s best to get it checked promptly.


2. Unexplained Drop in Water Level

A small amount of evaporation, about ¼ inch per day, is normal. But if you’re losing much more than that, your pool might be leaking.

A professional pool technician can inspect for different types of leaks, including:

  • Pressurized plumbing leaks
  • Suction line leaks
  • Multiport valve leaks
  • Hydrostatic valve leaks

Trying to pinpoint the problem on your own can be frustrating and time-consuming. A certified pool specialist has the tools and experience to identify and fix the issue efficiently, and may recommend a full pool replumb if the plumbing is deteriorating.


3. Cracks Forming in Your Pool Deck

New cracks in your pool deck can be more than cosmetic. When water leaks from the plumbing underneath, it can weaken the surrounding concrete and cause cracking.

If you also see puddles forming around those cracks, it’s a sign you should call for professional inspection right away.


4. A Sudden Spike in Your Water Bill

If your pool has an autofill system, a plumbing leak may go unnoticed until your next utility bill arrives. Continuous refilling can quietly drive up your costs each month.

If you haven’t changed your household water habits but your bill keeps climbing, the pool is a likely culprit. A qualified pool repair company can check for leaks and replace damaged plumbing or equipment as needed.
