Common Water Heater Issues and When to Call a Plumber

Hot water is something most homeowners don’t think about—until it’s gone. Whether your shower suddenly turns cold, your water heater starts making strange noises, or you notice water pooling around the unit, these issues are usually signs that something isn’t right. Understanding the most common water heater problems can help you decide when a quick fix is possible and when it’s time to call a licensed plumber.

At In A Flash Heating & Plumbing, we help homeowners across Medford and nearby cities like Somerville, Malden, and Everett diagnose and resolve water heater issues before they turn into costly emergencies.

1. Lack of Hot Water (or Running Out Too Fast)

One of the most common complaints we hear is, “My hot water doesn’t last anymore.” If your water heater runs out of hot water quickly—or you’re not getting any at all—several issues could be to blame.

Common causes include:

• A failing heating element (electric units)

• A malfunctioning gas burner or pilot light

• Sediment buildup reducing tank efficiency

• A water heater that’s undersized for your household

If your unit is older or repeatedly struggles to keep up with demand, it may be time to consider a professional water heater installation or even an upgrade to a tankless system for better efficiency and endless hot water.

2. Strange Noises Coming From the Tank

Popping, banging, or rumbling noises coming from your water heater are never a good sign. These sounds are often caused by sediment buildup at the bottom of the tank. As water heats up, trapped sediment hardens and creates noise while reducing efficiency.

Ignoring these noises can lead to:

• Overheating of the tank

• Premature failure of internal components

• Higher energy bills

A licensed plumber can flush the system, inspect internal components, and determine whether repair or replacement is the safer long-term option.

3. Visible Leaks or Water Pooling Around the Unit

Any water leaking from your water heater should be addressed immediately. In many cases, leaks point to failing connections or aging piping that may require professional pipe repair services. Leaks may come from:

• Loose fittings or valves

• A faulty temperature and pressure relief valve

• Cracks in the tank itself

Small leaks can quickly turn into major water damage if ignored. If you notice water pooling around your unit, it’s best to shut off the water supply and contact a professional right away for emergency plumbing service.

When Should You Call a Plumber?

While minor issues like adjusting the thermostat may be handled by homeowners, most water heater problems require professional attention. You should call a plumber if:

• You have no hot water at all

• The unit is making loud or unusual noises

• You notice leaks or corrosion

• The water heater is more than 8–12 years old

A professional inspection can prevent breakdowns, improve efficiency, and help you avoid unexpected failures.

Frequently Asked Questions

How long does a typical water heater last?

Most traditional tank water heaters last between 8 and 12 years with proper maintenance. Tankless systems can last even longer when serviced regularly.

Is it better to repair or replace a water heater?

If your unit is older, frequently breaking down, or inefficient, replacement is often more cost-effective than repeated repairs.

Can sediment buildup damage my water heater?

Yes. Sediment buildup reduces efficiency, increases energy costs, and can lead to overheating and tank failure if not addressed.Common Water Heater Issues and When to Call a Plumber
