Why Homeowners Choose McKeown Plumbing

Choosing who installs a tankless water heater matters just as much as choosing the equipment itself. When gas lines, venting, and existing plumbing are involved, experience is critical—you don’t want a crew learning on your home.

Our family of tradesmen has served coastal communities like Laguna Niguel and Laguna Beach for more than five decades. From older beach cottages to modern hillside homes, that experience helps us anticipate common issues like aging piping, corrosion, and tight venting conditions.

We hold both a Class A General Engineering license and a Class C Plumbing license in California, allowing us to handle more complex work involving plumbing systems, gas lines, and coordinated installations.

What sets our team apart:

  • 50+ years of local experience
  • Dual California licensing (Class A + Class C)
  • Experience with both older and newer homes
  • Non-commission technicians
  • Practical, no-pressure recommendations

We focus on what makes the most sense for your home—whether that’s repair, replacement, or a tankless upgrade as part of a larger project.

Is A Tankless Water Heater Right For You

Tankless units heat water on demand instead of storing it in a large tank. When you open a hot tap, cold water flows through a heat exchanger, and the burner or electric element turns on to warm the water as it passes through. When you close the tap, the system shuts down until the next call for hot water.

This design can provide continuous hot water within the limits of the system capacity, and it can free up space where a bulky tank once sat. For many households in coastal Orange County, this makes sense, especially when closet or garage space is tight. Energy use can also be more efficient because the heater is not keeping a large volume of water hot all day when nobody is home.

Deciding if a tankless system fits your home is not just a matter of liking these benefits. Several practical factors need to be reviewed carefully. These include the number of bathrooms, how many fixtures may run at the same time, the size and length of your existing gas line, where venting can safely exit the building, and the quality of your incoming water. Homes with very hard water, for example, may need additional filtration or regular descaling to support long-term performance.

Our role is to look at these details and give you straightforward guidance. If your current tank water heater still has useful life and can be repaired in a practical way, we will explain that option. If your home is an ideal candidate for tankless, we will talk through sizing and configuration so you understand why we recommend a particular model or layout. When a hybrid or different type of system is a better match, we will say so and explain why, instead of pushing a single product category.

Our Tankless Installation Process

Knowing what will happen during installation can relieve much of the stress around a major change to your hot water system. We follow a structured process so you know what to expect from the first call until your new heater is running.

We typically begin with a phone conversation to learn about your current heater, how old it is, what kinds of issues you are seeing, and how your household uses hot water. From there, we schedule an on-site evaluation. During this visit, our plumber inspects the existing unit, the surrounding plumbing, the gas line, electrical connections if present, venting, and the space available for equipment and clearances.

Using what we see in your home, we then work through sizing and layout. We consider expected flow rates from showers, tubs, and appliances, and we compare that to what various tankless models can deliver. We also take into account California building codes and local requirements in this part of Orange County, including rules for vent termination and combustion air. At this stage we review options with you and provide a written estimate that outlines the scope of work.

On the day of installation, our team protects nearby surfaces, such as flooring and walls, before we remove the old heater. We disconnect gas, water, and power carefully and haul the old tank out of the work area. We then place and mount the new tankless unit, run or adjust gas and water lines as planned, and route venting according to code and manufacturer guidelines. Throughout the process we keep the area as orderly as possible to limit disruption in your home.

Once everything is connected, we test thoroughly. This includes checking for gas leaks, confirming proper vent draft, purging air from the water lines, and confirming that the heater responds correctly at several fixtures. We then walk you through operation and basic maintenance tasks, such as cleaning inlet screens or scheduling descaling if your water conditions call for it. Finally, we clean up the work area so you are left with a working system, not a mess.

Serving Older Coastal Homes Safely

Many homes in and around Laguna Niguel have plumbing and gas systems that were installed decades ago under different standards than those used today. Some have galvanized piping that has been partially replaced over time, while others have compact water heater closets tucked into tight corners. These conditions can affect how a tankless water heater can be installed safely and efficiently.

Because our team at McKeown Plumbing has spent more than 50 years working in coastal Orange County, we are familiar with the way many of these systems were assembled. We understand the common pressure points, such as older gas lines that may not be sized for a high-output tankless unit, or vent paths that were acceptable for a natural draft tank but are not suitable for modern equipment. Our goal is to identify these issues before any work begins.

When we encounter unknowns, we rely on modern diagnostic tools where appropriate. For example, if we need to understand the condition of a drain line that serves your water heater area, we can use video inspection equipment to see inside the pipe rather than guessing. While this type of technology is often associated with sewer work, the mindset behind it is the same. We prefer to base decisions on what we can verify.

Our dual licensing as a Class A General Engineering and Class C Plumbing contractor allows us to plan and carry out work that might be more involved than a simple like-for-like replacement. If a tankless upgrade is part of a larger remodel or if structural changes are needed around a utility space, we have the credentials to coordinate that effort correctly. We also keep your property in mind, working to minimize disturbance to landscaping, hardscape, and interior finishes whenever possible.

Frequently Asked Questions

Is A Tankless Water Heater Worth It For My Home

A tankless system can be worth it when your home and usage patterns match what the equipment does best. We look at your household size, plumbing layout, gas or electrical capacity, and water quality before recommending anything so the decision is based on your actual conditions.

How Long Will My Tankless Installation Take

Most residential tankless installations are completed in a single workday, although timing depends on how much gas, vent, or plumbing modification is required. We review the plan with you beforehand so you know roughly how long hot water will be offline and can prepare your household.

Can My Older Laguna Niguel Home Handle A Tankless System

Many older homes can support tankless units once gas lines, venting, and sometimes electrical service are evaluated and, if needed, upgraded. Because we have extensive experience with coastal properties, we know what to look for and explain any required changes before work begins.

Do You Handle Permits & Inspections For Tankless Units

We handle the permitting process for the work we perform and coordinate required inspections with local authorities. Our Class A and Class C licenses reflect a strong focus on code compliance, and we design installations so they meet current California and local standards for safety.

How Often Does A Tankless Water Heater Need Maintenance

Most tankless units benefit from periodic service, often annually per manufacturer warranty requirements, depending on water hardness and usage. Maintenance typically involves flushing to remove scale and checking filters. During your installation, we discuss a schedule that fits your home and local water conditions.
