Your Fully Licensed Tankless Water Heater Plumber

Drain Pros is a fully licensed and insured tankless water heater plumber, not a general handyman treating tankless systems as an afterthought. Every technician we send out is trained specifically on tankless units, both gas and electric, and understands the unique demands these systems place on venting, gas lines, and electrical components that a traditional tank simply doesn’t have.

Our licensing ensures our work meets local plumbing codes, and our team carries insurance to protect your property throughout the job. We provide water heater services throughout Ventura County, the San Fernando Valley, and Santa Clarita, for both residential and commercial properties.

Whether you’re calling about an error code on your unit, scheduling routine maintenance, or considering a switch from a traditional tank, we start with a real diagnosis, not a guess. When you hire Drain Pros, you’re hiring a plumber with genuine tankless-specific experience, not just general water heater knowledge applied to a different type of unit.

What to Know Before You Book Plumbing Installation

A little planning up front saves time and money on any installation. Know what you’re replacing or adding, how much hot water you actually use, and where the unit will go. We also check your gas line, venting, and electrical setup during the first visit, so your quote is accurate and installation day has no surprises.

Why Switch to a Tankless Water Heater?

Tankless water heaters heat water only when you turn on the tap, so you’re not paying to keep 40 or 50 gallons hot around the clock. That usually means lower energy use and no running out of hot water mid-shower. Other benefits:

Endless hot water: Steady supply, even with back-to-back showers or laundry.
Space savings: Compact units mount on a wall and free up floor space.
Longer lifespan: Tankless systems typically outlast traditional tanks with proper maintenance.
Lower leak risk: No large tank of water that can rupture and flood your property.

CIPP tends to outperform simpler lining methods specifically when the damage is spread out, since the cured liner creates one continuous, jointless surface across the entire repaired section rather than requiring separate patches.

Signs Your Tankless Water Heater Needs Service

Tankless units are reliable, but they need attention when something changes. Call us if you notice:

Cold water bursts or inconsistent temperature: Often a sign of scale buildup or a failing sensor.
Little or no hot water: Could point to ignition, gas supply, or flow issues.
Error codes on the display: Your unit is flagging a problem you shouldn't ignore.
Rumbling or popping noises: Usually mineral deposits building up inside the heat exchanger.
Higher energy bills: A unit working harder than it should is losing efficiency.
Leaks around the unit or pipes: Small drips can quickly turn into water damage.

Regular flushing and annual maintenance catch most of these early and keep your system running efficiently for years.
