LEAK DETECTION SERVICES IN CINCINNATI
Not every plumbing leak is easy to see. The Drain Smith provides leak detection services in Cincinnati and surrounding areas to help locate underground water leaks, main water line leaks, slab leaks, and hidden plumbing issues before they lead to property damage, high water bills, or unnecessary digging. Our team identifies the source of the problem, explains your options clearly, and helps you move forward with the right repair.
Not every pool leak is easy to see from the surface. A pool can lose water from evaporation, equipment issues, fittings, cracks, or hidden leaks in the underground plumbing system. When the problem is coming from a buried pool line, guessing can lead to unnecessary digging, concrete removal, wasted water, and continued frustration.
The Drain Smith provides pool leak detection services in Cincinnati and surrounding areas to help locate underground pool plumbing leaks, return line leaks, suction line leaks, skimmer line leaks, main drain line issues, and hidden pool water loss before major repairs begin.
When you know where the pool leak is coming from, you can make a smarter repair decision, avoid unnecessary damage, and move forward with the right solution.
Is Your Pool Losing Water Faster Than Normal?
A pool that keeps losing water is trying to tell you something — and the answer almost never reveals itself by staring at the water line. Whether the loss is creeping in slowly over weeks or jumping noticeably day to day, the most common culprits live in places you can't see: underground return lines, suction lines, skimmer lines, main drain lines, and the buried plumbing that connects everything together.
The Drain Smith provides pool leak detection services in Cincinnati, Ohio and surrounding communities to help homeowners, property managers, and pool contractors locate hidden pool plumbing leaks before anyone breaks concrete or starts digging. We focus on the underground and plumbing side of pool leaks — the part that traditional pool service companies often aren't set up to diagnose.
Our goal is simple: pinpoint the leak so the repair plan is targeted, not guessed. If your pool is dropping water faster than evaporation explains, we can help you figure out what's actually happening.

Pool water loss is a normal part of owning a pool — but only up to a point. Evaporation, splash-out, and backwashing account for some of it. Beyond that, you may be looking at a plumbing leak.
Common signs of a pool plumbing leak:
Any one of these can have a non-plumbing explanation. Several together usually point to a leak that needs to be located before any repair decisions are made.
Most of a pool's plumbing is buried — running under the deck, the patio, the yard, and sometimes the surrounding hardscape. When one of those lines develops a leak, the water doesn't always surface in a useful place. It can saturate the soil silently, follow the path of least resistance, and leave you guessing about the source.
That's exactly where guessing gets expensive. The wrong response to an underground pool leak is to start breaking concrete or digging up the deck hoping to find the failure. The right response is to locate the leak first.
Underground pool leak detection helps with:
Our approach is consistent with how we handle underground leak detection for water service lines and other buried plumbing: locate first, dig second — and only when digging is actually necessary.

Return lines are the pressure side of your pool's plumbing — the lines that push filtered water back into the pool through the return jets. When a return line develops a leak, the leak is usually worse when the pump is running, because pressurized water is being forced out at the failure point.
Locating a return line leak precisely lets the repair plan be targeted — sometimes to a single fitting or a short section of pipe rather than the entire run.
Suction lines pull water from the pool toward the pump — through the skimmers and the main drain. Suction-side leaks behave differently than return-side leaks. Because the line is under vacuum when the pump is running, you often see air being drawn into the system rather than water spraying out.
Suction-side leaks can be tricky because they sometimes don't show obvious water loss at the surface. Identifying them requires reading the system's behavior — exactly the kind of diagnostic a plumbing-focused leak detection visit is built to provide.
Skimmer lines and main drain lines are often the most difficult pool plumbing components to inspect. They run from inside the pool structure out through buried pipe, frequently passing under decks, coping, or hardscape on the way to the equipment pad.
Skimmer leaks can occur at the skimmer body itself, at the connection point between the skimmer and the buried plumbing, or anywhere along the buried run. A skimmer-area leak often shows up as wet ground or settling right at the edge of the pool deck, or as pool water dropping until it reaches the level of the skimmer.
Main drain leaks are harder to diagnose because the drain sits at the bottom of the pool, and the line typically runs out and under the pool structure. Symptoms can include unexplained pool water loss that continues even when the pool is below the skimmer level, or visible loss tied to system pressure changes.
Both lines may be buried or otherwise inaccessible. A proper leak detection visit identifies whether one of these lines is the likely source so the repair conversation can be informed instead of speculative.
The most expensive mistake in pool leak repair is acting before knowing. Breaking concrete, removing decking, or excavating around a pool without first locating the leak almost always leads to either (a) repairs in the wrong spot, (b) far more demolition than necessary, or (c) both.
Pool leak detection before digging lets you:
If excavation does turn out to be necessary after the leak is located — particularly when the damaged line is under concrete or buried deep — we can coordinate with our excavation services. The difference is that the work is precise and purposeful instead of exploratory.
If you've already received a major pool plumbing repair estimate and want a second look before committing, our free second opinion approach applies to underground plumbing situations like this as well.
Pool leak detection isn't a one-size-fits-all service. The Drain Smith works with three distinct audiences — and each one comes to us with different priorities.
For homeowners with a residential pool that keeps losing water, we help:
For property managers responsible for community, HOA, or commercial pools, we help:
For pool builders and pool service companies that need a plumbing-focused leak detection partner, we provide:
A pool leak detection visit should answer one question clearly: where is the water actually going? Here's how we work through it.
We start with a conversation. When did you first notice the water loss? Is it worse with the pump on or off? Have you seen wet spots, air bubbles, or pressure changes? Your observations narrow the field before we even open a tool case.
We walk the equipment pad, the visible plumbing connections, and the area around the pool looking for tell-tale signs — wet spots, settling, condensation, drips, or unusual moisture in places that shouldn't be wet.
Based on the symptoms and visible clues, we form a working theory about whether the leak is most likely on the return side, the suction side, the skimmer line, the main drain line, or somewhere else in the buried plumbing.
Depending on the situation, this can include pressure testing pool lines, isolating sections of the plumbing, monitoring pump behavior, and using acoustic or electronic leak detection equipment to listen for the signature of escaping water.
We confirm whether the failure point is in accessible plumbing or in a buried line — and if it's buried, we work to pinpoint its location and approximate depth so any repair access is as small as possible.
You get a plain-language explanation of what we found, what it likely means, and what the realistic repair options look like. No pressure, no jargon, no sales pitch.
Sometimes that's a plumbing repair we can perform. Sometimes it's a recommendation to involve a pool builder or specialty pool company for non-plumbing concerns. Either way, you leave with clarity instead of guesswork.
Leak detection and leak repair are two different stages of the same problem. Detection answers the question "where is the leak?" Repair answers the question "what do we do about it?" — and the answer to the second question can only be made well after the first one has been answered honestly.
Once we've identified the source, the right next step depends entirely on what we found. Depending on the situation, the next stage may involve:
The Drain Smith is a Cincinnati plumbing, drain, sewer, water line, and underground leak detection company. For pools, our focus is the plumbing side — the buried lines, return and suction systems, skimmer plumbing, and main drain lines. We're not set up as a general pool cleaning, pool opening and closing, pool liner replacement, or pool resurfacing company. When those services are what you actually need, we'll say so and point you in a useful direction.

Signs of a pool leak include water dropping faster than evaporation explains, needing to refill more often than normal, wet or sunken areas around the pool, air bubbles in the return jets, equipment losing prime, water pressure changes, higher water bills, and water loss that varies depending on whether the pump is running. Any combination of these is worth investigating.
Some water loss is normal due to evaporation, splash-out, and backwashing. The exact amount depends on weather, pool size, and usage. If your pool is losing water noticeably faster than usual — especially after windy or hot weather has passed — that's a sign worth looking into.
Yes. Underground pool plumbing is one of our core focuses for pool leak detection. We use modern leak detection equipment and pool-system diagnostics to help locate hidden leaks in buried return lines, suction lines, skimmer lines, main drain lines, and the connections between them.
Almost any pool plumbing line can develop an underground leak. The most common are return lines, suction lines, skimmer lines, main drain lines, and the buried fittings and couplings that connect them. Older pools and pools with shifting soil or aging hardscape are especially common candidates.
Return line leaks often show water loss that's worse when the pump is running, because pressurized water is being pushed out at the failure point. You may also see wet ground or settling along the line's path, dampness near return fittings, or unusually high water usage.
Suction line leaks usually show air being drawn into the system — persistent bubbles in the pump basket, filter, or return jets; equipment losing prime; difficulty maintaining prime; and reduced circulation. Water loss may actually be worse when the pump is off, because gravity then drives water out of the failure point.
Yes. Skimmer lines run from the skimmer body through buried plumbing toward the equipment pad. They can leak at the skimmer connection, at fittings along the way, or anywhere in the buried run. A common visible sign is wet ground or settling right along the pool's edge near the skimmer.
Absolutely — that's one of the main reasons to do it. Locating the leak before any concrete is broken or any decking is removed lets the repair stay targeted instead of exploratory. It usually saves significant time, cost, and property damage.
No. Some pool leaks are at accessible fittings or above-ground connections and don't require any digging. When the leak is in a buried line or under concrete, some access may be required — but the goal of leak detection is to keep that access as small and targeted as possible.
No. Our focus is on plumbing-side pool leak detection and underground pool plumbing issues. We don't provide pool liner replacement, pool resurfacing, cosmetic pool repair, pool cleaning, or pool opening and closing services. If your situation calls for one of those, we'll point you toward the right type of professional.
