Signs You Need Water Heaters Service
Brown or rust-colored hot water (but clear cold water) usually means the tank lining has failed and the steel shell is corroding from the inside.
These noises come from steam bubbles forming under a thick sediment layer at the bottom of the tank, a sign the unit needs flushing or is near end of life.
Puddles around the water heater indicate a tank leak, a failing T&P valve, or a loose fitting that needs immediate attention to prevent water damage.
Fluctuating hot water temperature points to a failing thermostat, a damaged dip tube, or a heating element issue that a technician can diagnose in minutes.
Tank water heaters in the Permian Basin typically last 8 to 12 years. Units older than 10 years are at higher risk of sudden failure, especially without regular maintenance.
A sudden increase in your gas or electric bill without a change in usage often means the water heater is working harder due to sediment buildup or a failing component.
Rust on the tank exterior, around fittings, or on the flue indicates moisture exposure and potential structural weakness that can lead to a tank rupture.
Error codes on a tankless water heater often signal scale buildup in the heat exchanger, an ignition failure, or a flow sensor issue that requires professional descaling or repair.
Water Heaters Services We Provide
Water Heater Repair →
Our licensed plumbers diagnose and repair all tank water heater failures, including faulty thermostats, burned-out heating elements, leaking T&P valves, and corroded anode rods. Most repairs are completed in a single visit with parts carried on our trucks.
Water Heater Replacement →
When repair costs exceed 50% of a new unit or the tank is past its service life, replacement is the smart move. We size every replacement to your household's peak demand, handle code-compliant installation with expansion tanks and proper venting, and coordinate permits and inspections.
Water Heater Maintenance →
Annual maintenance extends your water heater's life by 3 to 5 years. Our service includes a full tank flush, anode rod inspection and replacement, burner and ignition system cleaning, gas connection leak testing, and T&P valve safety check.
Tankless Water Heater Repair →
Tankless systems are reliable but not maintenance-free. We troubleshoot error codes, replace failed ignition assemblies, clean flame sensors, repair flow control valves, and resolve temperature fluctuation issues across all major brands including Rinnai, Navien, and Rheem.
Tankless Water Heater Replacement →
Upgrading to tankless or replacing an aging unit requires precise load calculation, proper gas line sizing, and code-compliant venting. We handle the full scope — removal, installation, gas and electrical connections, and city inspection coordination — typically in 4 to 8 hours.
Descale Tankless Water Heater →
Hard water in West Texas deposits calcium and magnesium scale inside tankless heat exchangers faster than almost anywhere in the country. Annual descaling with a food-grade vinegar solution restores flow, prevents error codes, and protects your investment.
Repair or Replace? How to Decide
The 50% rule is the industry standard: if a single repair costs more than half the price of a new unit, replacement is the better investment. But age matters too. A 3-year-old water heater with a $350 thermostat repair has years of life left. A 10-year-old tank unit with the same problem is statistically close to additional failures — the repair buys time, but not much.
Tank water heaters typically last 8 to 12 years with maintenance. Tankless units last 15 to 20 years. If your tank unit is past year 8 and showing symptoms — rusty water, inconsistent temperature, visible corrosion — we generally recommend replacement rather than sinking repair dollars into aging equipment. We walk through the math with you during every consultation so the decision is clear, not pressured.
Consider the full picture: a new high-efficiency unit can cut water heating costs by 10% to 34% depending on the type. Factor in the remaining repair risk on an old unit versus the warranty protection on a new one. We provide a side-by-side cost comparison so you can see the 5-year total cost of ownership for each option.

Water Heater Maintenance in the Permian Basin
The Permian Basin has some of the hardest water in the country — mineral concentrations that the Water Quality Association classifies as very hard and that rank among the highest for any metro area in Texas. That mineral load is the single biggest threat to water heater longevity in this region. In tank units, calcium carbonate settles at the bottom and hardens into a layer that insulates the burner from the water. The burner runs longer, the tank overheats at the bottom, and the glass lining cracks. In tankless units, scale restricts the heat exchanger until the unit triggers a fault code and shuts down.
Annual maintenance is non-negotiable here. For tank units, that means a full drain-and-flush to remove sediment, plus an anode rod inspection — the sacrificial rod that protects the steel tank from corrosion. Once the anode rod is consumed, the tank itself starts corroding. For tankless units, annual descaling with a food-grade vinegar solution clears mineral deposits from the heat exchanger and restores factory efficiency. Pairing any water heater with a whole-home water softener dramatically extends equipment life and reduces energy costs.

Water heating accounts for roughly 20% of a home's total energy costs according to the U.S. Department of Energy, making it the second-largest energy expense after HVAC. Choosing the right system and maintaining it properly saves hundreds of dollars per year.
Resolv Services (TX Plumbing License #42668) installs, repairs, and replaces both tank and tankless water heaters from Rheem, Rinnai, AO Smith, Bradford White, and Navien. Our licensed plumbers size every unit to match your household's peak demand, fuel source, and the hard water conditions common across West Texas. We provide a written estimate before any work begins and handle all permit coordination.
Why Proper Sizing Matters
An undersized water heater runs out of hot water during peak demand. An oversized unit wastes energy heating water you never use. We calculate peak demand based on fixture count, number of occupants, and simultaneous use patterns.
For tankless installations, we factor in incoming water temperature — groundwater in the Permian Basin drops to the mid-40s Fahrenheit during winter, which directly affects the unit's flow rate and temperature rise. Proper sizing is the difference between a system that performs flawlessly and one that disappoints from day one.
We install and service all major water heater brands. Rheem Performance and Performance Plus series are our most-installed tank units — reliable, well-priced, and widely available for fast replacement. Rinnai RU series tankless units are our top recommendation for homes upgrading from tank to tankless, offering condensing efficiency and Wi-Fi monitoring.
AO Smith Signature and ProLine series provide solid mid-range tank options with long warranty coverage. Bradford White Defender Safety System units feature a sealed combustion chamber that prevents flammable vapor ignition — a safety feature we recommend for water heaters installed in garages. Navien NPE-A2 condensing tankless units deliver the highest efficiency ratings in our lineup at 0.97 UEF, making them ideal for homeowners focused on long-term energy savings.
We recommend specific brands and models based on your home's demand profile, fuel type, and budget — not manufacturer incentives.
Water heater efficiency is measured by the Uniform Energy Factor (UEF), which replaced the older Energy Factor (EF) rating in 2017. A higher UEF means more of the fuel's energy goes into heating water rather than being lost. Standard gas tank water heaters have UEF ratings of 0.58 to 0.65.
High-efficiency condensing tank models reach 0.80 or higher. Gas tankless units range from 0.82 for non-condensing models to 0.97 for condensing units like the Navien NPE-A2. Electric tank water heaters have UEF ratings of 0.92 to 0.95 because there is no combustion loss, but electricity costs more per BTU than natural gas in most of West Texas.
Heat pump water heaters achieve UEF ratings of 3.0 or higher by extracting heat from surrounding air, but they require a warm, spacious installation area and are less common in this region. We calculate the estimated annual operating cost for each option during your consultation so you can compare total cost of ownership, not just sticker price.
For tank water heaters, sizing is based on First Hour Rating (FHR) — the number of gallons of hot water the unit can deliver in the first hour of use. A family of 2 to 3 typically needs a 40-gallon tank with an FHR of 50 to 60 gallons. Families of 4 to 5 should look at 50- to 65-gallon tanks with an FHR of 70 to 80 gallons.
Larger households or homes with multiple bathrooms may need a 75-gallon unit or dual tank setup. For tankless water heaters, sizing is based on flow rate (gallons per minute) and temperature rise. You need to know how many fixtures you will run simultaneously and how much the unit needs to raise the water temperature.
In West Texas, incoming groundwater ranges from the mid-40s in winter to the low 70s in summer. A single shower uses 2.0 to 2.5 GPM. Running two showers and a kitchen sink simultaneously requires 6.0 to 7.5 GPM — which demands a high-capacity unit like the Rinnai RU199 (11 GPM max flow rate).
We perform this calculation during every consultation to match the right unit to your actual usage.
The Permian Basin sits on ancient seabed formations rich in calcium, magnesium, and other dissolved minerals. Municipal water treatment removes contaminants but does not soften the water. Dissolved hardness minerals arrive at the tap in concentrations that are roughly 3 to 5 times the national average — above 250 ppm in most Odessa and Midland neighborhoods.
This hard water creates three specific problems for water heaters. First, sediment accumulation in tank units creates an insulating layer between the burner and the water, forcing the unit to work harder and shortening its life from the national average of 10 to 15 years to roughly 8 to 10 years locally. Second, scale buildup inside tankless heat exchangers restricts water flow and reduces heat transfer efficiency, eventually triggering error codes that shut the unit down.
Third, accelerated anode rod consumption means the sacrificial rod that protects the tank from corrosion may be depleted in 2 to 3 years instead of the typical 4 to 5 years. A whole-home water softener installed upstream of the water heater addresses all three issues and is the single best investment for extending equipment life in this region.
Frequently Asked Questions About Water Heaters
A bottom leak usually traces to one of three things: a failing drain valve (often a cheap, repairable fix), the T&P relief valve discharging because pressure is too high, or the steel tank corroding through from years of sediment. Wipe the area dry and check the top connections first — a slow drip from above runs down and pools at the bottom, mimicking tank failure. If water seeps from the tank seam or the water is rust-colored and the unit is 8+ years old, the tank has failed and needs replacement. Shut off the power and water and call us before spending money on the wrong fix.
On a gas water heater, no hot water is usually a pilot that won't stay lit (often a failing thermocouple), a tripped gas control, or a bad gas valve. On an electric unit, it's typically a tripped breaker, a burned-out heating element, or a failed thermostat. If the water is warm but runs out fast, a bad lower element or dip tube is the likely cause. Most of these are common, repairable fixes we can handle in one visit.
That noise is water percolating up through a hardened layer of sediment on the bottom of the tank. Odessa and Midland's hard water builds sediment quickly — it insulates the burner from the water, wastes energy, and creates hot spots that stress the steel and shorten the tank's life. A professional flush usually quiets it and buys more years. If the tank is old and heavily scaled, we'll tell you honestly whether flushing is still worth it.
Rust-colored hot water usually means the anode rod — the sacrificial rod that protects the tank from corrosion — is used up and the tank has begun rusting from the inside. A rotten-egg smell is typically bacteria reacting with that rod. Caught early, replacing the anode rod is an inexpensive fix; left too long, the tank corrodes through and needs replacing. We can test and tell you which situation you're in.
The industry rule of thumb is the 50% rule: if one repair costs more than half the price of a new unit, replace it. Age matters too — tanks last 8 to 12 years nationally but 6 to 10 in our hard water. If the tank itself is leaking, replacement is the only real option, since a leaking tank can't be sealed and risks a sudden rupture. For valves, elements, thermocouples, or anode rods, repair usually makes sense — and we give you the honest math.
The most common cause here is sediment taking up space inside the tank — a 50-gallon tank full of scale holds far less hot water than it should. Other causes are a broken dip tube sending cold water to the top, a failed lower heating element, or a thermostat set too low. If your household has simply outgrown the tank, a larger unit or a tankless upgrade fixes it for good.
Nationally, tank water heaters last 8 to 12 years, but Odessa and Midland have some of the hardest water in Texas at 15 to 25 grains per gallon, which commonly cuts that to 6 to 10 years. Flushing the tank annually and replacing the anode rod every 3 to 5 years pushes you toward the high end. Tankless units last 15 to 20 years with regular descaling.
Most common repairs — thermocouples, valves, elements, or a full flush — run roughly $175 to $650 depending on the part and unit. A tank replacement typically runs $1,200 to $2,200 installed, and a tankless conversion $2,800 to $4,800. You get an upfront, written price before any work begins, so there are no surprises.
For many Permian Basin homes, yes — tankless units deliver endless hot water, last 15 to 20 years, and cut standby energy loss. The trade-offs are a higher upfront cost and the need for annual descaling in our hard water to keep scale from clogging the heat exchanger. We size the unit to your home and gas or electrical capacity and tell you honestly whether tankless or a high-efficiency tank is the better value for you.
Usually, yes. Because we stock common parts — thermocouples, elements, valves, and thermostats — most repairs are finished in a single visit. Standard tank replacements can often be done the same day you call; tankless installs sometimes need extra planning for gas or electrical upgrades. Call (432) 290-8511 and we'll give you a real arrival window.
