Water Heater Repair & Replacement in Los Angeles, CA

A water heater failure is rarely a total surprise if you know what to watch for — most units show warning signs weeks or months before they fail completely, from rusty water to a pilot light that won't stay lit to a tank that's simply old enough that replacement makes more sense than another repair.

24/7 Rooter Service repairs and replaces both tank and tankless water heaters across Los Angeles. For repairs, we diagnose the actual failed component — thermocouple, heating element, gas valve, thermostat — rather than defaulting to a replacement recommendation. For replacements, we size the new unit to your household's real usage, not a like-for-like swap of whatever was already there.

Gas and electric units fail differently and need different installation approaches, and we handle both.

Signs You Need This Service

• No hot water at all, or hot water that runs out much faster than it used to
• Rusty, discolored, or metallic-tasting hot water
• Popping, rumbling, or banging sounds from the tank during heating cycles
• Water pooling at the base of the unit
• A pilot light that won't stay lit, or repeatedly needs relighting
• The unit is 10+ years old, the typical lifespan for a standard tank water heater

Residential & Commercial Service

Residential work covers standard 40-75 gallon tank units and tankless systems sized for household demand. Commercial water heaters for restaurants, multi-unit buildings, and offices need higher-capacity units and different code requirements, which we account for at the quoting stage.

Frequently Asked Questions

Should I repair my water heater or replace it?

If the tank itself is leaking, replacement is the only option — a corroded tank can't be safely patched. If it's a specific component and the tank is under 10 years old, repair is usually the better value. We'll give you a straight answer either way.

How long does a replacement actually take?

Most standard tank replacements are completed same-day, typically within a few hours. Tankless conversions can take longer if gas line sizing or venting changes are needed.

Is tankless worth the higher upfront cost?

It depends on your household's usage and how long you're staying in the home. Tankless costs more upfront but uses less energy over time and never runs out of hot water — we can walk through real numbers for your situation.

What size water heater do I actually need?

Sizing depends on household size, bathroom count, and usage patterns — not just replacing what was there before, especially if the household has grown since the original install.

Do you handle the permit?

Yes, we handle permitting where required, particularly for tankless conversions involving gas line or venting changes.

What's an expansion tank, and do I need one?

It absorbs pressure created when water heats and expands in a closed system. Many older LA homes don't have one, and current code often requires it — we'll flag this during any replacement.
