Signs It’s Time to Repair or Replace Your Water Heater

When a water heater stops working, life can become uncomfortable. Knowing how to resolve the problem and get the water heater back up and running quickly can mean the difference between a warm shower or a cold one. But how do you know if you’re looking at a simple repair or a total replacement? Below are a few common water heater issues and what may be your best bet for resolving the issue: 

Not Heating

If cold water is flowing even when the hot water tap is turned on, the pilot light on your gas water heater may have gone out. This can happen occasionally and can be a quick fix. If relighting the pilot doesn’t work, there may be an issue with the gas line. Never attempt to fix a gas issue on your own. Call a professional for help with gas line issues.

Strange Noises

Popping noises from your water heater may indicate a build-up of minerals and sediment at the bottom of the water tank. Over time this sediment build-up can trap water causing pressure to build. To prevent damage to the hot water tank, give our team of licensed plumbers a call by phone at (302) 367-7915 to schedule a water heater repair service. Once we arrive at your house, we will flush the system to remove the excess minerals that are causing the noises.


A leaking water heater needs immediate attention. Calling a certified technician as soon as a leak is spotted can help you avoid a bigger mess. Although not always the case, a leaking water heater typically means it’s time for a replacement.


Water heaters don’t last forever. The average lifespan of a gas water heater is 10-15 years with diligent maintenance. If your water heater is more than 10 years old or you’re experiencing issues, give our team of licensed contractors a call at (302) 367-7915 to book an appointment. We offer fast and dependable water heater installation and repair services to homes in areas such as Easton, Darby, Newark, and Upper Darby. Our staff is trained to repair or replace water heaters from a variety of manufacturers.

Extend The Life of Your Water Heater 

Water heaters are an investment. Proper maintenance will ensure your investment lasts. Extend the life of your water heater by flushing it at least once a year. This flush will remove the sediment that has built up and lower the risk of corroding and rusting.
