Why Choose GLV Plumbing for Gas Water Heater Replacement in Norwalk, CT?
A large share of homes in Connecticut use private wells, which can be acidic or carry iron, manganese, or radon that require treatment. Sediment that settles in the bottom of gas tanks overheats the steel and cuts tank life. We set up each new heater so sediment can be flushed and the anode rod can be checked.
- Safety First, Gas appliances require careful handling, and our technicians are rigorously trained in all safety protocols and code requirements for gas water heater installation.
- Energy Efficiency, We help you pick modern gas water heaters that can lower your energy bills compared to older models.

Large Capacity 75 Gallon Gas Heaters in Norwalk, CT
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model.

A high-recovery unit can be a good middle ground when space is limited. We walk you through recovery rates so you choose the right fit.

40 and 50 Gallon Tank Replacement in Norwalk
The 40 and 50 gallon gas tank is the workhorse of most Connecticut homes. When yours starts leaking from the bottom seam or produces rusty water, replacement is the only real fix. We match the new tank's height and diameter to your space and reuse the venting when it is in good shape. Newer tanks are sometimes taller due to efficiency standards, so we check clearance before ordering. Most of these jobs take about two to three hours.
Thermal Expansion Tank Installation in Norwalk
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can strain your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a correctly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.

Frequently Asked Questions About Gas Water Heater Replacement in Norwalk
The cost for gas water heater replacement in Norwalk, CT usually ranges from $1,200 to $3,500, depending on the unit size, brand, efficiency and any needed plumbing changes. Factors like gas line upgrades or ventilation improvements can impact the final price.
GLV Plumbing installs and services all major brands of gas water heaters, including Rheem, Bradford White, A. O. Smith, State and more. We help you choose the best brand and model to suit your needs and budget.
Common signs include a lack of hot water, rust-colored water, banging or rumbling noises from the tank, leaks around the base or repeated pilot light outages. An aging unit, usually over 10 to 12 years old, is also a clear sign.
It is risky. Gas leaks, poor venting and incorrect relief valve installation can create fire and carbon monoxide hazards. A licensed plumber also handles permits and inspection.
Tank warranties usually range from 6 to 12 years depending on the model. We add our own labor warranty on the installation.
Most new gas water heaters come with a manufacturer's warranty, typically covering the tank for 6 to 10 years and parts for 1 to 2 years. GLV Plumbing also provides a labor warranty on our installation for extra peace of mind.
Water pooling at the base, rusty hot water, rumbling or popping sounds and a tank over 10 years old are common signs. A leak from the tank itself cannot be repaired.
Atmospheric vent water heaters use natural convection to vent combustion gases up a chimney or flue. Power vent models use an electric fan to force gases out, allowing for more flexible venting options and often higher efficiency due to cleaner combustion.
