Installing a 50 Gallon Electric Water Heater the Right Way

March 20, 2026

In Arch Plumbing, every installation of all plumbing works is done with high care to safety, plumbing code and durability. Recently, our team also completed a project in which we substituted an older unit and installed a new 50-gallon electric water heater to replace a homeowner in St. Charles County.

It is typical of projects such as these that occur in the homes in which older water heaters have started to lose efficiency or reliability. By replacing the unit prior to complete failure, the homeowners would prevent unexpected leaks, water damages, etc. and the loss of hot water at the very moment.

We always strive to get equipment properly installed the first time and all the elements related to the system should be up to date plumbing standards.

Removing an Outdated Saddle Valve

We found an existing saddle valve attached to the line of humidifiers during this installation.

Older plumbing systems employed saddle valves due to the fact that they were simple to install. Nevertheless, they are no longer popular in the contemporary plumbing systems due to their ability to limit the flow of water as well as their tendency to leakage in the long run.

In the installation, handling of the saddle valve was done to enhance the stability of the system.

Installing a Code-Compliant Quarter-Inch Shutoff Valve

Rather than installing the old type of valve, our plumbers fitted a 1/4 inch shutoff valve to the supply of water to the humidifier.

This upgrade provides several benefits:

  • The connection meets current plumbing code requirements

  • The homeowner can easily turn the water supply on or off

  • The system becomes more reliable and easier to maintain

  • Future service or maintenance becomes simpler

These small improvements help ensure the entire plumbing setup works efficiently and safely.

Why Proper Water Heater Installation Matters

A water heater installation involves much more than simply swapping one unit for another. Professional plumbers check several factors to ensure everything works properly:

  • Correct electrical connections

  • Proper water supply connections

  • Pressure and safety components

  • Code-compliant valves and fittings

  • Reliable shutoff options for future maintenance

Paying attention to these details helps prevent leaks, improves energy efficiency, and extends the life of the water heater.

When It May Be Time to Replace Your Water Heater

Many homeowners begin considering replacement when they notice signs such as:

  • Inconsistent hot water

  • Water heater age over 10 years

  • Rust-colored hot water

  • Strange noises coming from the tank

  • Small leaks near the unit

Replacing the system before it fails completely can save money and prevent emergency plumbing situations.

Frequently Asked Questions

How long does a 50-gallon electric water heater last?

Most 50-gallon electric water heaters last 8–12 years depending on water quality, maintenance, and installation quality. Regular inspections and flushing the tank can help extend the lifespan.

Is a 50-gallon water heater enough for a family?

A 50-gallon electric water heater is typically suitable for 3–4 people in a household, depending on daily hot water usage such as showers, laundry, and dishwashing.

Saddle valves are commonly found in older plumbing systems but are not recommended by modern plumbing standards. They can restrict water flow and are more likely to leak. Installing a proper shutoff valve provides better reliability and control.

Most professional water heater installations take 2–4 hours, depending on the plumbing setup and whether upgrades like new valves or connections are required.
