Why Your Hot Water Doesn’t Last & What You Can Do About It
The Call We Get All the Time: “Why Is My Hot Water Running Out So Fast?”
If you’ve noticed your hot showers turning cold halfway through, you’re not alone. One of the most common plumbing calls we get is from homeowners frustrated that their water heater just isn’t keeping up like it used to.
In many cases, the issue isn’t with the size of your tank or your usage, it’s what’s going on inside your water heater that’s the real problem.
Let’s break down what’s happening and how you can fix it for good (without replacing your water heater every few years).
The Culprit: A Burned Out Lower Heating Element
In electric water heaters, there are typically two heating elements: one at the top and one at the bottom. The bottom element does most of the heavy lifting when it comes to heating a full tank of water.
Over time, especially in areas with hard water, minerals like calcium and magnesium build up at the bottom of the tank. This sediment creates a layer of insulation between the heating element and the water, forcing it to work harder. Eventually, the element burns out.
So what happens next?
The water heater only heats from the top element, reducing your supply of hot water
You notice lukewarm or short showers
You call a plumber (like us!)
Why Most People Just Replace the Water Heater
In many cases, by the time a homeowner calls, their water heater is:
5–10+ years old
Showing signs of wear (rust, leaks, noise)
Not energy-efficient compared to newer models
Rather than repair the heating element (which may only be a temporary fix) many customers choose to replace the unit entirely.
While this solves the immediate problem, it doesn’t address the underlying cause: hard water buildup.
The Better Long-Term Fix: Install a Water Treatment System
If you want your next water heater to last longer, perform better, and cost you less over time, the smart move is to treat your water at the source.
Installing a water softener or filtration system can:
Prevent mineral buildup in your tank
Protect your new (or existing) water heater
Improve water quality throughout your home
Reduce wear on faucets, dishwashers, and washing machines
Help soap and shampoo lather better (goodbye hard water stains!)
