Most River homes were built in the 1940s, 50s, and 60s. The bones are solid, but the plumbing infrastructure was designed for a different era and a conventional tank water heater sitting in a hot garage, working overtime through summer heat, is one of the least efficient setups you can have. When you switch to a tankless system, that changes. You get hot water on demand, lower monthly energy costs, and a unit that’s built to last 20-plus years instead of the 8 to 12 you’d get from a standard tank.
There’s also something worth knowing about River’s water supply. The local municipal water system measures around 15.2 grains per gallon. That’s classified as very hard water, and it accelerates mineral scale buildup inside tankless heat exchangers faster than most homeowners realize. A properly installed system, sized and set up with your home’s water quality in mind, performs better and lasts longer than one that was just swapped in without that assessment. That’s the difference between a 25-year investment and one that starts underperforming in five.
The energy savings are real too. A two-year field study comparing standard tank units to tankless found a 37% reduction in water heating energy use per household. In a neighborhood where homes hold their value, that kind of long-term efficiency gain isn’t just a utility bill win it’s a home value conversation.
We founded Murray Plumbing in 2009 with a straightforward principle: River homeowners deserve straight answers and honest pricing not quotes that balloon after the job starts. That’s still how every job runs today.
River sits within our core service area, and we know this community. We’ve worked in the mid-century ranch homes throughout the neighborhood, dealt with the older gas line configurations common in homes built decades ago, and navigated the local permit process more times than we can count. That familiarity matters when the infrastructure in your home is 60 or 70 years old and a generic recommendation won’t cut it.
Our 4.7 out of 5 Google rating across 93 reviews reflects what customers consistently say: we showed up on time, the price didn’t change, and the job got done right. That’s the standard on every call.
It starts with a real assessment of your home’s existing setup not a sales pitch. Before anything is recommended or quoted, our technician evaluates your current gas line capacity, venting configuration, and available space. In River’s older ranch-style homes, this step matters more than it does in newer construction. Gas lines from the 1950s and 60s were sized for the appliances of that era, and a tankless unit draws differently than a conventional tank. If an upgrade is needed, you’ll know the full cost before any work begins not after.
Once the assessment is done and you’ve agreed to move forward, we handle the permit with the local Building Department. This is required work under California Plumbing Code, and skipping it creates real risk failed home inspections at resale, potential insurance claim denials on a home worth hundreds of thousands of dollars. The permit gets pulled, the installation gets done, and the required inspection gets scheduled. You don’t manage any of that.
The installation itself typically completes the same day. We remove the old unit, install and test the new tankless system, and leave the workspace clean. After the local inspection clears, you have a fully permitted, code-compliant system with documentation you can hand to a buyer or an insurance adjuster without hesitation.

A tankless water heater installation with us isn’t just a unit swap. It includes a full infrastructure evaluation before the quote, the installation itself, any gas line or venting modifications the system requires, local permit acquisition, and coordination of the post-installation inspection. The price you’re given before the job starts is the price you pay when it’s done.
For River homeowners running renovation projects kitchen remodels, bathroom additions, or ADU builds on the neighborhood’s larger ranch lots we size the installation to handle the full demand of an expanded home. A gas tankless unit delivers 5 to 10-plus gallons per minute, which covers two showers and a dishwasher running at the same time without anyone getting cold water. If you’re adding an ADU, the system can be assessed to serve both units from a single higher-capacity setup rather than adding a second water heater and doubling your long-term maintenance.
River’s hard water conditions are also factored into every installation. The setup includes guidance on an annual descaling schedule to keep the heat exchanger performing at full efficiency across the system’s full lifespan. It’s a detail that most plumbers skip and one that makes a measurable difference in how long your investment actually lasts.
Yes and it’s not optional. Your local jurisdiction requires a permit for all water heater installations under California Plumbing Code Section 502.1, and a building inspection is required after the work is complete. This applies to River just as it does to every other area within the state.
The reason this matters goes beyond just following the rules. If you sell your home and River properties move regularly an unpermitted installation will surface during the buyer’s inspection and can kill or delay the deal. More immediately, if an unpermitted water heater is connected to a leak or fire, your homeowner’s insurance has grounds to deny the claim. We handle the entire permit process on your behalf, from filing to final inspection. You don’t call the building department, fill out forms, or schedule anything. It’s included in the job.
The honest range for a full tankless installation unit, labor, and any necessary gas line or venting work typically falls between $1,400 and $3,895, with a national average around $2,629. Where your job lands in that range depends on what your home’s existing infrastructure requires. In River, where many homes were built in the 1940s through 1960s, it’s not uncommon for the original gas line to need resizing to support a modern tankless unit’s flow demand. That work, if needed, is scoped and priced before anything starts.
We provide a complete quote upfront labor, materials, gas line modifications if applicable, and permit fees. Nothing is added after the work begins. Several customers have noted their final bill came in under the original estimate. That’s not a marketing line; it’s just how we operate. You’ll know the full number before a single pipe is touched.
In most cases, yes but it requires an honest assessment first. The mid-century ranch homes throughout River were built with gas line configurations designed for the appliances of that era: older furnaces, standard tank water heaters, and gas ranges with much lower BTU demands than a modern tankless unit. A tankless system needs a sufficient gas supply to fire at full capacity, and an undersized line will cause performance problems or prevent the unit from working correctly.
Before any recommendation is made, we evaluate your existing gas line size, the distance from the meter to the installation point, and your home’s total gas demand. If the line needs upgrading, that scope and cost are included in your upfront quote. It’s a solvable problem in the vast majority of River homes it just needs to be identified before the unit is selected, not discovered after it’s already mounted on the wall.
It’s one of the most overlooked factors in a tankless installation, and it’s directly relevant to River. The local municipal water supply tests at approximately 15.2 grains per gallon. That’s classified as very hard water, and over time, the mineral deposits it leaves behind accumulate inside a tankless unit’s heat exchanger. Left unaddressed, that buildup reduces heating efficiency and can significantly shorten the system’s lifespan.
The good news is that this is completely manageable with an annual descaling service. We account for River’s water hardness during installation and provide clear guidance on a maintenance schedule that keeps the system running at full efficiency. A tankless unit that’s properly maintained in your local water conditions will still reach its 20-plus year lifespan. One that isn’t maintained may start losing performance in as few as five years. It’s a simple, low-cost annual step that protects a significant investment.
For most River homes, the installation itself is completed the same day typically within a few hours once our technician is on-site. The timeline can vary depending on what the infrastructure assessment uncovers. If the gas line needs modification or the venting configuration requires adjustment, that adds time to the job. But because we do a full evaluation before the work starts, there are no mid-job surprises that extend the timeline unexpectedly.
The permit process runs parallel to the installation. We file with the local Building Department and schedule the required post-installation inspection. The inspection is a separate appointment after the install is complete, but it doesn’t disrupt your hot water access the system is operational before the inspector arrives. From the time you call to the time you have a fully installed, inspected, and permitted tankless system, most River homeowners are looking at same-day installation with the inspection following within a few business days.
For River specifically, the answer is yes and the reasoning is straightforward. Buyers in this area are looking for signs that the home has been maintained and modernized thoughtfully. A permitted, inspected tankless water heater installation is exactly that kind of signal. It tells a buyer the home has a water heating system with a 20-plus year lifespan, lower operating costs, and documentation that the work was done to code.
An unpermitted installation, on the other hand, creates problems at closing. Buyers’ inspectors flag it, lenders sometimes require it to be addressed before funding, and it opens liability questions that can slow or derail a sale. A properly permitted tankless installation through us gives you a clean record to hand over at closing and in a neighborhood where homes move regularly and competition among sellers is real, that’s not a minor detail.
