Your water bill just jumped, and you can’t explain why. Maybe your pool’s water level is suddenly dropping faster than usual. Before you assume it’s just evaporation, it’s worth taking a closer look. You may have also noticed a damp patch near the equipment pad, a sign that points straight to a leak.
PoolTec works with Katy homeowners every week to track down pool leaks before they turn into bigger pool repair issues, and clay soil is often part of the conversation. If you’ve noticed your water level dropping faster than usual, or a damp patch near the equipment pad that wasn’t there last month, the ground itself may be the reason why.
How Katy’s Ground Works Against Your Pool
Katy sits on expansive clay soil, and that soil expands when it absorbs moisture and contracts when it dries out. This constant shifting causes ground movement beneath and around your pool shell.
If the soil moves enough, it can stress plumbing lines, shift a gunite pool’s structure slightly, or create small gaps around fittings and the main drain. None of this means your pool is doomed, but it does mean pool leaks show up here more often than in areas with stable, sandy soil.
The soil affects your whole property, not just your swimming pool. If you’ve noticed cracks in your driveway or soft spots in your yard, the same clay is likely responsible. When that soil pulls away from pipe fittings or shifts under the pool floor, water finds a way out.
Obvious Signs Your Pool Might Be Losing Water
Most pool leaks leave clues before they turn into major structural or equipment damage. Here’s what to watch for:
- Losing more than a quarter-inch of water per day. Normal evaporation typically accounts for about a quarter-inch daily, more in hot, dry, or windy weather conditions. If your pool loses water well beyond that, something else is going on.
- Cloudy pool water that won’t clear. A pool leak near the plumbing can pull air into the system, throwing off your chemical balance and leaving you with a cloudy pool no matter how much you treat it.
- Cracks or soft spots around the pool deck or equipment pad. These often indicate water is escaping underground and softening the soil nearby.
- A pump running longer than usual or losing prime. If your pool pump struggles to hold suction, air may be entering through a cracked pipe or loose fitting.
- Algae or unusually green grass near the pool. Extra moisture from a leak feeds nearby plant life, so a suddenly lush patch of lawn is worth noting.
If any of these sound familiar, the ground movement from our clay soil could be a contributing factor, but the only way to know for sure is to test.
DIY Pool Leak Detection: The Bucket Test
The bucket test is one of the simplest ways to detect leaks, and is a good first step for any pool owner who suspects a problem. It’s free, and it helps you determine whether you’re dealing with evaporation or an actual leak.
- Fill a bucket with pool water and place it on a step in the shallow end.
- Mark the water level inside the bucket and the water level of the pool itself, using tape or a marker.
- Turn off the pool pump and let the pool sit undisturbed for 24 hours.
- After a day, compare the two marks.
If the pool’s water level dropped more than the level inside the bucket, this indicates there is likely a leak somewhere in the system. If both levels dropped about the same amount, you’re probably just seeing normal evaporation.
Narrowing Down the Location
Once you’ve confirmed water loss beyond typical evaporation, the next question is location. Leaks generally come from one of three places: the pool shell itself, the plumbing lines, or equipment like the pump, filter, or heater.
A few ways to narrow this down before calling in help:
- Run the bucket test with the pump on, then off. If the pool loses more water with the pump running, the leak is likely in the plumbing. If it loses about the same either way, suspect the shell or skimmer.
- Check the equipment pad for wet spots. Dampness around the pump, filter, or pipe fittings usually points to a leak in that area.
- Look at the skimmer and main drain. These fixtures sit at pressure points where clay soil movement can loosen seals over time.
These checks can narrow down the general area, but you may not be able to pinpoint exactly where the leak exists. That level of detail requires a closer look at the specific system involved, whether that’s the plumbing, the shell, or the equipment itself.
When to Call a Pool Leak Detection Professional
If your checks point to a leak, whether it’s water loss beyond normal evaporation, a damp equipment pad, or plumbing that loses more water with the pump running, it’s time to bring in PoolTec. Our team can confirm the source and get you a clear plan for pool repair.
PoolTec’s leak detection service goes deeper than a simple visual inspection. We may use dye testing to spot cracks in the pool shell, and pressure testing on the plumbing lines to check for air or water escaping through a pipe, fitting, or connection point. In most cases, we can locate the exact hole or crack where the pool is leaking without unnecessary digging, which keeps repair services faster and less invasive.
We also check equipment like the pump and heater, since a failing part can sometimes mimic leak symptoms even when the pool itself is sound. If you’ve been wondering, “should I replace my pool pump?” instead of repairing a leak, our team can walk you through that decision once we know the real source of the problem.
Don’t Let a Small Leak Become Serious Damage
Pool leaks usually don’t stay small for long, especially with Katy’s shifting clay soil working against your plumbing and pool structure. What starts as a small amount of daily water loss can, over a few months, lead to serious damage. Eroded soil beneath the pool deck, damaged equipment, or a cracked shell that costs far more to fix than an early repair would have.
If you suspect a leak, don’t wait a week hoping it resolves on its own. Reach out to PoolTec, and we’ll help you determine the location and cost of repair before the problem grows. Contact us today to schedule your pool leak inspection.
