What is Water Heater and How Does It Work?
A water heater is a household appliance that heats and stores — or heats on demand — the water used for bathing, cooking, cleaning, and laundry. It’s one of the hardest-working systems in your home, operating quietly in the background every single day. Most residential water heaters in Mountain View fall into two main categories: tank-style water heaters, which store a reservoir of preheated water (typically 40–80 gallons), and tankless (on-demand) water heaters, which heat water instantly as it flows through the unit.
Tank water heaters use either natural gas or electricity to maintain a constant supply of hot water. Tankless models, increasingly popular in Mountain View’s energy-conscious homes, only activate when a hot water tap is opened — eliminating standby energy loss. Both types require professional installation and periodic maintenance to operate safely and efficiently.
Understanding how your water heater works helps you recognize early warning signs of trouble and make informed decisions about repair versus replacement. Whether your home has a traditional gas tank unit in the garage or a wall-mounted tankless system, Drain & Water’s licensed plumbers can service it.
Pro Tip: Check the manufacturer’s label on your water heater for the model number and installation date. Knowing the age of your unit helps our technicians provide faster, more accurate diagnostics when you call.

Expert Water Heater Repairs in Mountain View
Fast, Reliable Hot Water Restoration
A malfunctioning water heater doesn’t always mean you need a full replacement. Many common issues — inconsistent water temperature, strange rumbling or popping noises, discolored water, slow recovery times, or small leaks around fittings — can be resolved with a professional water heater repair.
At Drain & Water, our licensed technicians diagnose the root cause before recommending any work. Common water heater repairs we perform for Mountain View homeowners include:
Thermostat replacement — Restores accurate temperature control
Heating element repair — Fixes electric units that aren’t producing hot water
Anode rod replacement — Prevents internal tank corrosion and extends unit lifespan
Pressure relief valve (T&P valve) repair — Ensures safe operation and prevents dangerous pressure buildup
Pilot light and gas valve service — Addresses ignition failures on gas water heaters
Sediment flushing — Removes mineral buildup that causes noise and reduces efficiency
Leak repair — Addresses dripping connections, valves, and supply lines
We provide upfront pricing before any work begins — no surprises. If your water heater is beyond repair, we’ll give you an honest recommendation and walk you through your replacement options.
Pro Tip: If your water heater is making a loud popping or rumbling sound, it’s likely sediment buildup at the bottom of the tank. A professional flush can restore efficiency and quiet the unit — but if ignored, it can lead to premature tank failure.

Pro Tip: When replacing a water heater, consider upgrading to a higher energy-factor (EF) rated model. Even a small improvement in efficiency can save Mountain View homeowners significantly on monthly utility bills over the life of the unit.
Types of Water Heaters We Service in Mountain View
Drain & Water’s licensed plumbers are trained to repair, install, and maintain all major types of residential water heaters, including:
Conventional Tank Water Heaters (Gas & Electric)
The most common type in Mountain View homes. Stores 40–80 gallons of preheated water for immediate use.
Tankless (On-Demand) Water Heaters
Heats water only when needed, offering endless hot water and lower energy consumption. Ideal for Mountain View homeowners looking to save space and reduce utility costs.
Heat Pump (Hybrid) Water Heaters
Uses electricity to move heat from the surrounding air into the water tank. Extremely energy-efficient and eligible for many California rebates.
Condensing Water Heaters
A high-efficiency gas option that captures exhaust heat to preheat incoming water. Best suited for homes with high hot water demand.
Point-of-Use Water Heaters
Small, compact units installed near a single fixture for instant hot water delivery. Great for bathrooms or kitchens far from the main water heater.
Not sure which type is right for your home? Call us at (408) 564-0580 for a free consultation.
Your unit is over 10 years old
Your water heater is 8–12+ years old — Most tank water heaters have a lifespan of 8–12 years. Tankless units can last 15–20 years with proper maintenance.
You're calling for repairs more frequently
Frequent repairs — If you’re calling for repairs multiple times a year, replacement is likely more cost-effective.
Rusty water coming from hot water taps only
Rusty or discolored hot water — Brown or rust-colored water coming from your hot water tap often indicates internal tank corrosion.
Visible rust or corrosion on the tank exterior
Visible corrosion or rust on the tank — External rust, especially around fittings and connections, is a sign of advanced deterioration.
Water pooling around the base of the heater
Leaking or pooling water around the base — A leaking tank typically cannot be repaired and requires immediate replacement.
Your energy bills have increased noticeably
Rising energy bills — An aging, inefficient water heater works harder to heat water, driving up your utility costs.
Inconsistent water temperature
Inconsistent water temperature — Fluctuating temperatures or water that never gets fully hot signals a failing heating element or thermostat.
The tank makes loud rumbling or cracking sounds
Strange noises — Loud banging, cracking, or popping sounds indicate heavy sediment buildup that may be beyond a simple flush.
Signs You May Need a Water Heater Replacement
Knowing when to repair versus replace your water heater can save you money and prevent unexpected breakdowns. Watch for these warning signs.
Pro Tip: Don’t wait for a complete failure. A proactive replacement on your schedule is far less stressful — and less expensive — than an emergency replacement after a tank rupture floods your garage or utility room.
If you’re noticing any of these signs, contact Drain & Water for an honest assessment.

Switching to a Tankless Water Heater in Mountain View, CA
Tankless water heaters are one of the most popular upgrades for Mountain View homeowners — and for good reason. Unlike traditional tank units that continuously heat a stored reservoir of water, tankless systems heat water on demand as it passes through the unit, delivering an endless supply of hot water while using significantly less energy.
Benefits of switching to a tankless water heater:
Endless hot water — No more running out mid-shower or waiting for the tank to recover
Energy savings — Tankless units can be up to 24–34% more energy-efficient than conventional tank heaters for homes that use 41 gallons or less of hot water daily (per the U.S. Department of Energy)
Space savings — Wall-mounted tankless units free up valuable floor space in garages, closets, and utility rooms
Longer lifespan — Tankless water heaters typically last 15–20+ years compared to 8–12 years for tank models
Reduced risk of water damage — No tank means no risk of a catastrophic tank failure and flood
Switching from a tank to a tankless system may require upgrades to your gas line, venting, or electrical supply. Drain & Water handles the entire conversion process, including permitting, gas line work, and installation — all to California code.
Pro Tip: If you have hard water (common in parts of Mountain View and Santa Clara County), schedule annual descaling for your tankless water heater. Mineral buildup can reduce flow rate and efficiency over time. Ask Drain & Water about our water heater maintenance plans.
Frequently Asked Questions About Water Heaters in Mountain View, CA
How long does a typical water heater last in Mountain View?
Most conventional tank water heaters last between 8 and 12 years, while tankless models can last 15 to 20 years or more with proper maintenance. Factors like water quality, usage patterns, and regular servicing all affect lifespan. Drain & Water can inspect your unit and let you know where it stands.
Do I need a permit to replace a water heater in Mountain View, CA?
Yes, the City of Mountain View and the State of California require permits for water heater installations and replacements to ensure compliance with local building codes and energy standards. Drain & Water handles all permitting as part of our installation service so you don’t have to worry about the paperwork.
How often should I have my water heater serviced?
We recommend annual maintenance for both tank and tankless water heaters. For tank units, this includes flushing sediment, inspecting the anode rod, and testing the pressure relief valve. For tankless units, descaling is essential — especially in areas with hard water. Regular maintenance extends the life of your system and keeps it running efficiently.
What size water heater do I need for my Mountain View home?
The right size depends on the number of people in your household and your peak hot water demand. A family of four typically needs a 50-gallon tank water heater or a tankless unit rated for at least 8–10 GPM (gallons per minute). Our technicians will assess your specific needs and recommend the ideal size during a consultation.
Is a tankless water heater worth it for a Mountain View home?
For many Mountain View homeowners, yes. Tankless water heaters provide endless hot water, take up less space, and are significantly more energy-efficient than tank models. They also last nearly twice as long. The upfront investment is higher, but the long-term energy savings and extended lifespan often make it a smart financial decision.
Can Drain & Water service both gas and electric water heaters?
Absolutely. Our licensed plumbers are trained and equipped to repair, install, and maintain both gas and electric water heaters, including conventional tank, tankless, hybrid heat pump, and condensing models. Whatever type of system your Mountain View home has, we can service it.
What should I do if my water heater is leaking?
First, turn off the water supply to the unit and, if it’s a gas heater, turn off the gas valve. Avoid contact with pooling water near electrical connections. Then call Drain & Water at (408) 564-0580 for emergency service. A leak can indicate a failing tank, a loose connection, or a faulty valve — all of which require professional diagnosis.
