Water Heaters

EZ Plumbing has been installing and servicing water heaters in Los Angeles since 1989 — California license C-36 #583868. We do tank-style replacements, tankless installations and conversions, anode and element repairs on heaters that have life left in them, and recirculation pump installations. Most replacements are same-day on standard sizes. For anything urgent — wet floor under the heater, no hot water, popping or rumbling sounds with discolored water — call (818) 908-2710. The rest of this page covers what to check before calling, tank versus tankless for LA homes specifically, how long water heaters actually last under LA’s water chemistry and seismic requirements, what the code and permit picture looks like, and what replacement costs.

Signs Your Water Heater Needs Service (and Which Are Emergencies)

Call right now if: there is water on the floor around the base of the tank (the tank has corroded through or a fitting has failed and the unit is actively leaking); the temperature-and-pressure (T&P) relief valve is discharging water through its drain line (the valve is doing its job — the tank may be over-pressurized or overheating and continuing operation is unsafe); you have no hot water at any fixture and the unit is making popping or banging sounds (heating element is firing into a sediment layer and may crack the tank); or you smell gas anywhere near a gas-fueled heater. Gas smell — leave the building and call SoCalGas at 1-800-427-2200 first.

Schedule a service call (not emergency) if: hot water is running out faster than it used to (sediment is reducing effective tank capacity); water has a metallic or rusty tint when running hot but is clear cold (interior tank corrosion or sacrificial anode rod is depleted); you hear rumbling or popping under normal use but nothing else is wrong (mineral scale on the burner or element — annual flushing usually restores normal operation if the tank is otherwise healthy); the recovery time between showers has gotten noticeably worse over the past year; the unit is older than 8 years on a gas tank or 10 on an electric tank.

Plan for replacement (not panic) if: your tank is 10+ years old and showing any of the above symptoms. Continuing to repair a tank past 10 years rarely makes financial sense — the next failure is usually the tank itself, and a tank failure floods whatever’s around it. The annual flush, T&P valve check, and anode rod inspection are worth doing on any tank under 8 years old; on a 12-year-old tank, you’re spending money to delay a replacement that’s coming anyway.

What to Check Before You Call — Honest DIY Diagnostic

Some “no hot water” calls have a simple fix that doesn’t need a service call. Walk through this first.

Gas tank, no hot water: check that the pilot light is lit (look through the access window at the bottom of the unit; you should see a small steady blue flame). If it’s out, follow the relight instructions printed on the unit’s label — usually involving holding the control knob in pilot position, depressing the ignitor button while keeping the gas valve open, and waiting 60 seconds before turning the knob back to “on.” If the pilot won’t stay lit after relighting, the thermocouple is failing (a common $80-150 part) or the gas supply has an issue. If you don’t get a click and a smell of gas during the ignitor sequence, the gas is off somewhere upstream — check the shutoff valve on the supply line above the heater (handle should be in line with the pipe = open). After all that, if it’s still not working, call us.

Electric tank, no hot water: check the breaker panel for a tripped 30-amp double-pole breaker labeled “water heater” — reset it once. If it trips immediately again, an element has shorted to ground; don’t keep resetting. Check the high-limit reset button (a small red button behind the upper access panel on the tank, sometimes covered by an insulation flap). Press it once. If neither works, you likely have a failed heating element or thermostat — a service call but not an emergency.

Tankless, no hot water: almost always a fault code on the unit’s display (Rheem, Navien, Rinnai, Noritz, Takagi all display error codes when something goes wrong). Look up the specific code in the manual — the most common are flow-related, ignition-related, or venting-related, and several have homeowner-fixable causes like a low gas-supply pressure during high simultaneous demand. If the code persists or you can’t find it in the manual, call us with the code on hand so we can bring the right parts.

Tank vs Tankless — Which Is Right for Your LA Home

This is the most common question we get, and the honest answer is “it depends on three things.”

How many simultaneous demands you have: a 40-gallon tank handles two showers running at once and not much more. A 50-gallon tank handles two showers plus a dishwasher. Tankless can handle whatever its rated flow can deliver continuously — for a properly sized unit, that’s 3-4 simultaneous fixtures with no recovery time. If you have a 4-bathroom home with adults who shower simultaneously in the morning, tankless makes sense. For a 2-bathroom home with sequential use, a properly sized tank is fine.

Your gas line capacity: tankless units burn at significantly higher BTU rates than tank units — typically 150,000–200,000 BTU/hr for a whole-house tankless versus 30,000–40,000 BTU/hr for a tank. Most older LA homes have a 3/4-inch gas line feeding the water heater, sized for the tank. A whole-house tankless retrofit usually requires upgrading to a 1-inch supply, which means new gas piping from the meter to the heater and an LADBS permit and pressure test for the upgrade. Budget for this as part of the tankless conversion — it’s not a hidden cost we surprise you with, but a real one.

How long you plan to own the home: tankless units last 15-20 years with annual maintenance; tank units last 8-12 years in LA water. The upfront cost differential (tankless is roughly double the all-in installation of a comparable tank) usually pays back over the unit’s life through equipment longevity plus energy savings — DOE estimates 8-34% energy savings depending on household hot water use, with higher percentages for lower-use households. If you’re planning to sell within 5 years, the math is less clear — buyers don’t always value the tankless premium at the cost of replacement.

What we’d advise against: point-of-use small tankless units installed at individual bathrooms as a “patch” without rerouting the supply line. They work, but they’re often a workaround for a fundamental problem (an undersized main heater, a too-long hot-water line, an out-of-spec recirculation loop) that should be solved at the source.

How Long Water Heaters Actually Last in LA — and Why

Manufacturer warranties typically run 6-12 years on tank units. The actual service life in LA is on the lower end of that range for two reasons: water hardness and seismic mounting standards.

Hard water and sediment buildup

LA water is moderately hard — generally in the 100-300 ppm CaCO₃ range depending on the blend MWD is delivering to your area that month. Calcium and magnesium minerals precipitate out of solution at temperatures above about 140°F and settle to the bottom of the tank as sediment. Over 8-12 years that sediment layer becomes a thermal insulator: in a gas tank, the burner has to heat through it before reaching the water, the bottom of the tank overheats, and the metal fails earlier than it would in soft-water service. In an electric tank, the lower heating element ends up buried in sediment, overheats, and burns out. The popping or rumbling sound from an aging tank is the sound of steam pockets forming and collapsing under the sediment layer — once you hear it consistently, you’re inside the failure window.

An annual tank flush — connecting a hose to the drain valve, opening it, and letting several gallons run until clear — significantly extends tank life on hard water. We can do this as part of a service visit, or you can do it yourself if you’re comfortable; the procedure is on most manufacturer websites and it takes about 30 minutes. Skipping it for 5+ years on LA water is one of the most common reasons a tank fails before its warranty period.

Anode rod depletion

Every tank has a sacrificial anode rod — magnesium or aluminum — designed to corrode preferentially so the tank lining doesn’t. In LA’s moderately hard water, the anode is typically depleted by year 5-7. After that, the tank lining itself starts corroding. Pulling and replacing the anode at year 5 (we do this as a service visit, typically under an hour) is the single highest-leverage maintenance step for extending a tank’s life — easily adds 3-5 years to a tank that would otherwise fail at year 9.

Tank corrosion (the failure mode you can’t fix)

Once the anode is gone and the lining starts to fail, you’ll see water with a rusty tint coming from hot taps, eventually a visible drip from the tank itself, and finally the wet-floor emergency call. There is no economical repair for a corroded tank — replacement is the only answer. If your tank is 10+ years old and showing rust in the hot water, plan replacement before it becomes an emergency.

LA-Specific Code: Permits, Seismic Strapping, T&P, and Venting

Water heater installation in Los Angeles is a permitted activity. LADBS requires a plumbing permit before replacement work begins, and an inspection after. We pull the permit and schedule the inspection as part of the job — every time. Skipping the permit is not a corner you want cut; it shows up at home sale, in insurance claims, and during refinances.

Seismic strapping is mandatory in California per Health & Safety Code §19211. Two straps minimum — one in the upper third of the tank, one in the lower third — anchored to the wall studs, not the drywall. The straps must be at least 1.25-inch wide metal or equivalent. Older installations almost universally fail current strap standards — you’ll see a single nylon strap, or straps anchored only to drywall, or no straps at all. We bring the strapping up to current standards on every replacement; it’s not optional and the inspector will fail the job if it isn’t done correctly.

Temperature-and-pressure (T&P) relief valve is the safety device that prevents tank explosion when something goes wrong with the thermostat. The valve must discharge through a drain line that terminates safely — at floor level (not threaded at the discharge end, not blocked, not above floor level so a sudden discharge doesn’t spray scalding water on someone). We install or verify the discharge line on every replacement.

Drain pan is required for tanks installed in locations where a leak would cause damage — closets, attics, finished spaces above living areas. The pan must have its own drain line to the exterior or to an approved drainage point. This catches the eventual leak and gives you time to act before water damage spreads.

Combustion air and venting for gas units: atmospheric draft heaters need adequate combustion air supply in the space they’re installed (a closed closet without combustion air vents will fail inspection), and they need code-compliant venting — proper rise, proper diameter, proper termination. We verify and correct these on every replacement; older installations frequently have venting that was acceptable under previous code cycles but doesn’t meet current requirements.

How Quickly We Can Replace a Failing Water Heater

Same-day replacement is realistic for standard tank sizes (30, 40, 50, and 75 gallon gas; 40, 50 gallon electric) when the existing installation meets current code with just a like-for-like swap. If the existing installation needs the gas line resized, the venting redone, new seismic strapping into wall studs that aren’t where they need to be, or a drain pan added, expect the job to extend into a second day for materials and permitting. Tankless installations almost always run 1-2 days because of the supply line upgrades and exterior venting requirements — there are very few “same-day tankless” jobs that aren’t cutting corners.

If you have a leaking tank and need water shut off while replacement is scheduled, we can dispatch immediately to cap the supply and stop the active damage, then return for the proper replacement. The stabilization visit is a separate line item but it stops the bleeding while parts and permits are arranged.

Cost Ranges for Water Heater Service in LA

What drives the variance: tank capacity, fuel type (gas tends to cost slightly more than electric on like-for-like installations because of venting requirements), tankless vs tank, whether the existing installation meets current code (often older installations need gas, venting, or strapping work as part of the swap), permit fees, and location accessibility (a heater in an upstairs closet behind tile takes longer than one in an open garage). For a standard like-for-like gas tank replacement with no code upgrades needed, the all-in cost — unit, labor, permit, strap upgrade if required, T&P verification, haul-away of the old unit — typically runs in the $1,800-$4,200 range. Tankless conversions, including supply line upgrade and exterior venting, typically run $4,500-$10,200. We provide a written estimate after assessing the existing installation in person; phone quotes are ranges, not commitments.

When You Shouldn’t Call Us Yet

A tank that’s working but the water isn’t hot enough — first check the thermostat dial on the side of the tank. Manufacturers ship with thermostats set conservatively (around 120°F); turning it up to 130°F gives noticeably hotter water without the scald risk of higher settings. Don’t go above 140°F unless your dishwasher requires it; higher temperatures accelerate sediment formation and increase scald risk for children and elderly residents. A gas pilot that won’t stay lit — try the thermocouple replacement (about $30 for the part, 20 minutes of work with a wrench) before scheduling us. A popping or rumbling sound but otherwise normal operation — annual flush first; if that doesn’t fix it, then call.
