If your water heater is leaking, we find exactly where the leak is coming from and repair it. We don’t install or replace water heaters, so if yours needs a full replacement, we’ll tell you honestly instead of selling you a service we don’t provide. Whether the water is pooling at the bottom of the tank or dripping from a fitting near the top, the cause is usually identifiable without guesswork, and most water heater leaks are worth acting on promptly rather than waiting to see if they stop.
Water pooling at the base of your water heater usually means the tank itself has developed a leak, most often from internal corrosion or a failed drain valve, and once the tank is leaking, it typically needs to be addressed rather than left to continue.
These two causes point in different directions, which is why the distinction matters:
Santa Ana's hard water is a real factor here: mineral buildup inside a tank accelerates the corrosion that eventually causes a bottom leak, which is part of why we see this pattern often in the area's older housing stock. We locate exactly which of these two causes is behind your specific leak before recommending next steps, rather than assuming the worse-case scenario by default.
This is sometimes described as a water heater leaking from bottom of the tank, or a hot water heater leaking from bottom, and while a genuine tank-shell leak does mean the tank has corroded through and needs replacing, not every case is the tank itself, it can also be a drain valve that won't seat or a fitting above weeping down the side, which is exactly why we test before assuming the worst.
A leak from the top of your water heater is usually different from a tank-corrosion leak, and often points to a loose or failing connection rather than the tank itself.
The cold water inlet, hot water outlet, and the temperature and pressure (T&P) relief valve are the most common sources: a loose fitting can often be tightened or resealed, while a T&P valve that's discharging water may be doing exactly what it's designed to do, releasing pressure that's built up beyond a safe level, which is worth investigating rather than ignoring.
A water heater leaking from top like this is usually the better outcome of the two, since the connections are accessible and a fixable joint is the more common finding rather than a dead appliance.
A leaking water heater is not usually an immediate safety emergency. It can create real risks: electrical hazards if water reaches wiring or outlets, water damage to floors and walls, and mold if left standing. It's worth acting on promptly rather than waiting.
The real risk from a leaking water heater is rarely the leak itself in isolation, it's what standing water does over time. Water reaching an electrical outlet or wiring near the unit is a genuine electrical hazard. Water left on a floor for days can warp flooring, damage drywall, and create the damp conditions that lead to mold, which is a symptom worth addressing by shutting off the water and calling for a leak check, not something we diagnose or remediate ourselves.
None of this means panic, a leaking water heater is a common, manageable problem, but it does mean it's worth shutting off the water supply and getting it looked at rather than letting it sit. If you're dealing with active flooding or a fast, heavy leak right now, our 24/7 emergency line is answered day or night, in English or Spanish; scheduled detection visits otherwise run Monday through Saturday, 7am to 6pm.
Age is the first thing worth knowing when a water heater starts leaking, because it decides whether repairing the leak is sensible or whether you are about to spend money on a tank near the end of its service life. A tank unit's life is finite by design, a tankless unit's is longer, and the manufacturer's own figure is on the label.
The reason is simple: most leaks that come from the tank body itself are corrosion, and corrosion is a function of years and water chemistry, not bad luck. A hot water heater leaking at eight years from a fitting is usually a repair. The same tank leaking from the shell at eleven years is usually telling you something else.
We give you the age reading as part of the visit. If the leak is at a fitting, a valve or a connection, that is a repair and we do it. If the tank shell itself has failed, we say so plainly, because at that point a repair is not the honest recommendation and you need a replacement unit from an installer. We detect and repair leaks; we do not sell or install water heaters, which is exactly why our answer on this question has nothing riding on it.
So how long do hot water heaters last? Read the rating plate on your own unit: the manufacture date is on it, and the manufacturer's warranty term is the most reliable guide you have to expected service life for that specific model, more reliable than any general average.
Not every drop of water near a water heater is a leak. A gas water heater can produce condensation on its exterior during cold weather or right after the burner cycles, especially on tanks with a shorter, wider profile common near a garage or exterior wall.
A genuine leak tends to produce a steady puddle that returns after you dry the area, while condensation is usually a light film that doesn't reappear the same way once wiped down and the unit's had time to warm evenly.
If you're not sure which you're looking at, that's exactly the kind of call worth a professional look before you assume the worst, and it's part of why our detection visit comes with a no-find-no-fee guarantee: if we check and it turns out to be condensation, you haven't paid for a repair you didn't need.
The same question comes up all over a house, not just at a water heater. Is it condensation or a leak? sets out four tests that separate them, including the paper-towel one.
The drain valve near the base and the temperature and pressure relief valve near the top are the two parts most likely to be the actual source of what looks like a “water heater leak.” Both are individually repairable or replaceable parts, distinct from the tank itself, and identifying which one is actually failing is often the difference between a small, contained repair and an unnecessary tank-replacement conversation you don't need to have yet.
This part is sometimes called the water heater pressure relief valve, or simply the water heater relief valve, and it's a safety device, not a defect, when it drips because system pressure has climbed too high. A pressure relief valve water heater owner finds discharging constantly still deserves a prompt look, and it's never something to cap or plug yourself. When the source of a hot water tank leaking isn't obvious from the outside, that's exactly what a detection visit is for, establishing whether the water is coming from the unit itself, a connection, or a nearby line that only appears there.
A general plumber or a water heater installer can look at a leaking unit, but figuring out precisely which part is actually failing, the tank itself, a drain valve, a fitting, or the T&P relief valve, is what determines whether you're looking at a small, inexpensive repair or a genuine end-of-life tank.
That's the specific skill Miguel Torres and our detection team focus on: identifying exactly which of these is happening before recommending anything, using thermal imaging and moisture readings rather than assuming the worst from the outside. We don't install or replace water heaters ourselves, which means we have no incentive to steer you toward a bigger job than your leak actually calls for.
If the tank itself is failing and a full replacement is the honest answer, we'll tell you that directly and point you toward it, rather than blur repair and replacement into one sales conversation, an easy line to blur when the same company profits from both.
Once you've spotted water near your water heater, the next steps are the same regardless of which cause turns out to be behind it, and there's one separate safety question worth addressing directly first. A gas-fired water heater can occasionally develop a gas smell, which is a different, urgent safety issue from a water leak.
A gas smell is a separate hazard from the water leaks covered on this page, and we treat it as its own distinct safety matter rather than folding it into general leak troubleshooting.
Shut off the water supply to the unit, and if you can safely do so, shut off power or gas as well, then call for a detection visit rather than guessing further from where the water is pooling. From here, this page walks through exactly what to do right now, what happens once you call us, how long detection and repair take, what it costs, and the guarantees and service area behind all of it.
You tell us what you’ve noticed. We locate the leak with acoustic and thermal equipment before anything is opened up. We mark the exact spot and explain what we found in plain language. You get a written quote on site, and the same crew does the repair.
The detection visit is a flat $150 to $500, credited toward the repair if you go ahead. The full sequence — what helps before we arrive, what happens at each step, and the four things you get at the end — is on what happens on a leak detection visit.
There's no fixed number of hours we can promise, and we won't invent one just to give you a tidy answer. A detection visit is usually quicker than a slab leak visit, since a water heater's components, the tank, drain valve, fittings, and T&P valve, are all accessible in one spot rather than buried under a foundation, but the exact time still depends on how clear the source is once we're actually looking.
If the cause turns out to be a repairable part, like a drain valve or a loose fitting, that repair is typically a same-visit job. If the tank itself is corroded and failing, there's no repair to perform at all, since a corroded tank can't be repaired from the inside, and the honest next step is a referral to a water heater installer rather than us extending the visit into work outside our scope. We'll tell you which situation you're in as soon as we know, rather than estimate a timeline before we've actually looked.
Every visit starts with our flat-rate detection fee, $150 to $500, credited toward the repair if you move forward, the same policy we use across every service we offer. That covers thermal imaging, moisture readings, and a hands-on check of the drain valve, relief valve, and fittings to tell you exactly what's failing.
What the repair itself costs depends entirely on what we find, and we won't invent a number here just to fill space. A loose fitting or a failed drain valve is a smaller, more contained repair than most plumbing jobs; if it's the tank itself that's corroded, there's no repair price to quote at all, since that's a replacement conversation with a water heater installer, not a repair we perform.
Once we know exactly what's happening with your unit, we give you a firm written quote before any work starts, never a phone-estimate guess. For a repair of this size, financing usually isn't the deciding factor it can be on a larger job like a whole-house repipe, but if a repair does turn out to be more involved than expected, that's worth raising during your on-site quote.
We're based in Santa Ana and see this exact pattern often in the area's older housing stock, where hard water accelerates the tank corrosion described above. We serve Santa Ana and the surrounding central Orange County cities in our service area; see the full list to confirm we cover your specific city.
One other question comes up alongside the leak questions, and the useful answer is that it's a different problem entirely.
Water heater not heating, or hot water heater maintenance. Neither is a leak, and neither is what we do. We detect and repair leaks from existing units; we do not install or replace water heaters, and we do not service burners, elements or thermostats. If the unit is dry and simply not producing hot water, a plumbing or appliance contractor is the right call, and we will tell you that rather than book a visit we cannot help with.
This page is written by Miguel Torres, Senior Leak Detection Technician, trained specifically in the acoustic, thermal, and moisture-detection methods used to trace a leak like this to its exact source. Carlos Mendez, our Repair & Repipe Technician, is fully bilingual in English and Spanish, part of how we serve Santa Ana's Spanish-speaking households in their preferred language; read more about our bilingual service.
We're a new company, and we say so directly rather than pretending otherwise. What we can offer instead of a long review history is a named team, transparent published pricing, and the two guarantees below, stated in plain language rather than buried in fine print.
If we can't locate the leak during your detection visit, there's no detection fee. The detection visit itself is a flat-rate charge of $150 to $500, credited toward the repair if you move forward. Every repair we complete carries a 2-year workmanship warranty. See our full guarantees and warranties for the complete list.
We find the exact source (tank, drain valve, fitting or T&P valve) before anyone talks about replacing it.
(714) 386-7923Call or text, day or night Book a Detection VisitNot usually an immediate emergency. It carries real risks: electrical hazard if water reaches wiring, water damage to floors and walls, and mold if left standing. Shutting off the water and getting it checked promptly is the right response.
Shut off the water supply to the unit, shut off power or gas if you can do so safely, move valuables away from the standing water, and call for a leak detection visit to identify the exact source.
Look for standing water or a steady, recurring puddle at the base, damp fittings near the top connections, or water pooling that returns after you dry the area. A recurring puddle points to a real leak; a light film that doesn’t return after wiping and the unit warming evenly is more likely condensation.
The most common causes are internal tank corrosion (often accelerated by hard water), a failed drain valve, a loose or failing top connection, or a temperature and pressure relief valve releasing built-up pressure.
Once the tank itself is corroded and leaking, that’s generally a sign the tank has reached the end of its usable life, since the leak comes from the tank’s internal lining failing rather than a repairable part. A leak from the drain valve or a top connection, by contrast, is often a separate, repairable issue that doesn’t mean the tank itself is failing.
No need for alarm, but it’s still worth addressing promptly. Still having hot water just means the tank hasn’t failed completely; the leak itself, wherever it’s coming from, is worth identifying and addressing before it causes water damage.
A genuine leak produces a puddle that returns after you dry the area; condensation is usually a light film, more common in cold weather or right after the burner cycles, that doesn’t reappear the same way once the unit’s had time to warm evenly. If you’re unsure, a detection visit settles it, and our no-find-no-fee guarantee means you don’t pay a detection fee if it turns out to be condensation.
No. We detect and repair leaks in your water heater. If your unit needs a full replacement, we’ll tell you honestly rather than offer a service we don’t provide.
No. Detection is non-invasive: thermal imaging and moisture readings work from outside the unit, and checking the drain valve, relief valve, and fittings doesn’t require opening a wall or flooring. Repair itself is limited to whatever specific part is actually failing, a valve or a fitting, not an exploratory search.
If our equipment genuinely can’t locate the source during your paid detection visit, you don’t pay the detection fee. That’s the no-find-no-fee guarantee described above, applied the same way here as on every other service we offer.
It depends entirely on the cause. A leak from the drain valve or a loose fitting is often a smaller, worthwhile repair that doesn’t mean the tank itself is failing. A leak from tank corrosion generally does mean the tank has reached the end of its usable life, since the tank can’t be repaired from the inside, and at that point a full replacement through a water heater installer is the more honest answer than a repair we can’t actually perform.
