When the hot water stops, the first thought is usually the same: do I need a new water heater, or can this be fixed? It is also the moment when you are least likely to want to spend money on something you do not need.
This guide will help you sort it out, and tell you what to do right now if you have a leak.
If your water heater is leaking, start here
Water around the base of a tank is a serious warning sign. While you arrange help:
- Turn off the water supply to the unit using the shutoff valve on the cold water line.
- Turn off the power or gas to the water heater. For an electric unit, switch off its breaker. For gas, use the control on the unit. If you smell gas, leave the home and get help.
- Keep people and pets away from standing water, especially near electrical outlets or appliances.
- Call a plumber. We offer 24/7 emergency service.
A leak does not always mean the tank has failed. Sometimes it is a fitting or a connection. Either way, do not wait on a leak.
Problems that often point to a repair
A water heater is a collection of parts, and most of the components inside can be replaced. If the unit is fairly new, a repair can be the right call when you are seeing things like:
- Water that is not as hot as it should be.
- Inconsistent temperatures.
- Low hot water pressure.
- A leak at a connection or valve, with the tank body dry.
These symptoms can come from parts that wear out, and replacing a part may let you wait on a new unit. We tell you when a part is all you need.
Problems that often point to replacement
Replacement tends to be the better move when:
- The tank can no longer hold water. The tank itself cannot be repaired, so if the tank body is leaking, you need a new water heater.
- The unit is old. Most tank water heaters last about 10 years. Once yours passes the seven-year mark, start planning.
- Repairs keep repeating. If you are calling a plumber again and again, the repair money is often better put toward a new unit.
- The water is rusty or discolored, or you hear rumbling and popping from sediment buildup, which can point to corrosion and wear inside the tank.
- Your energy bills keep climbing. An aging, inefficient unit costs more every month.

If you do replace, check the permit rules first. In New Hanover County, the county’s permit chart lists a water heater replacement as needing no permit when a licensed contractor installs it, and as needing electrical/gas and plumbing permits when a homeowner does it (DIY). The chart covers replacements, so a change such as a different fuel, a new location or a tankless unit may need permits. Outside New Hanover County, check with your own county or town.
The question to ask: what will this repair buy me?
A useful way to decide is to ask what a repair gets you. If the answer is “a few more years on a newer unit,” repair often makes sense. If the answer is “a short extension on an old tank that is likely to need replacing anyway,” putting the money toward a new unit is usually smarter.
If the unit is old and you are going to replace it soon regardless, you may also benefit from the energy efficiency of a new one. If you are thinking about switching types, compare tank vs. tankless water heaters first.

Frequently asked questions
How do I know if my water heater needs repair or replacement?
If the tank itself is leaking or can no longer hold water, you need a replacement. If the unit is newer and the problem is a part, such as something affecting temperature, or the leak is at a fitting or valve, a repair may be enough. Age matters too: past about seven years, start planning ahead.
How long does a water heater last?
Most tank water heaters last about 10 years, and tankless units commonly last close to 20.
Is a leaking water heater an emergency?
It is serious. Shut off the water supply to the unit, turn off its power or gas, keep clear of standing water and call a plumber.
Do you offer emergency water heater service?
Yes. We offer 24/7 emergency service so you are not stuck without hot water. Call (910) 616-3238 and we will walk you through your options.
