Expert Tankless Water Heater Repair in
Southern California

Endless Hot Water. Lower Bills. Zero Tank.

Tired of running out of hot water mid-shower? Sick of a bulky tank hogging closet space and quietly draining your energy bill? Wiseway Plumbing installs, services, and repairs tankless water heaters that heat water the moment you need it, and stop the moment you don’t.

New Tankless Installation

Whether you’re building new, replacing a failing tank, or upgrading for resale value, we’ll size, source, and install the right tankless unit for your household. We handle:

• Sizing the right flow rate (GPM) for your home and fixture count
• Gas line and venting upgrades when needed
• Electrical upgrades for electric tankless models
• Permitting and code compliance
• Removal and disposal of your old tank water heater
• Full system test and walkthrough so you know how to use it

We install both gas (natural gas and propane) and electric tankless units from the brands homeowners trust, including Rinnai, Navien, Rheem, and Noritz.

Tank-to-Tankless Conversions

Converting an existing home from a tank to a tankless system is more involved than swapping like-for-like. It can require new gas lines, larger venting, a condensate drain, and sometimes electrical work. We’ve done it hundreds of times and we’ll tell you up front exactly what your home needs, what it’ll cost, and how long it’ll take.

Tankless Water Heater Repair

A tankless system that’s acting up doesn’t always mean replacement. Most issues are fixable in a single visit. We diagnose and repair:

• No hot water or cold water sandwiches
• Inconsistent water temperature
• Error codes on the unit display
• Ignition failure or burner issues (gas models)
• Reduced flow or low pressure
• Mineral and scale buildup
• Leaks at fittings, connections, or the heat exchanger
• Fan, sensor, and igniter failures
• Venting and exhaust problems

We service every major tankless brand, not just the ones we install. Bring us into the picture and we’ll get you back to hot showers fast.

Annual Tankless Maintenance & Flushing

Hard water and mineral scale are the number-one killers of tankless water heaters. An annual descaling flush keeps your heat exchanger clean, your unit running efficiently, and your warranty intact. Most manufacturers require it.

Our maintenance visit includes:

• Full descaling and vinegar flush of the heat exchanger
• Cleaning of the inlet water filter
• Inspection of venting, gas connections, and condensate lines
• Check of error logs and system performance
• Replacement of any worn parts before they fail

Skip the flush and you’ll feel it first in your energy bill, then in a no-hot-water call to us.
