01Water Heater Replacement in Charlotte, NC

Replacing your water heater typically involves fewer plumbing-related concerns than installing a new one. However, we still have to check some key components before starting the replacement.

02Check Your Current Plumbing

First, we have to examine the plumbing connecting to your old water heater, which could explain why it failed. Even though water heaters degrade slowly over time, some external plumbing issues can hasten their decline. For instance, there may be a leak at the connection between the plumbing and the water heater. If so, the water seeping out can cause your water heater to corrode faster than it normally would. If you have a gas-heated water heater, we may also have to check the gas supply valve. If, for example, it doesn’t open all the way, that could result in poor water heater performance and its early demise.

03Shut Off Your Old Water Heater’s Supply

Once we’ve thoroughly checked for any possible plumbing issues, we will shut off the water headed to your water heater to start plumbing your new heater. In most cases, your new water heater will be about the same size as your old one, especially if it didn’t break down because it was too small for your home.

04Empty Your Old Water Heater’s Tank

Once we’ve stopped the cold water flowing to the water heater and closed the valve at the hot water outlet, we run the hot water using the valve or receptacle closest to your water heater. Then, we connect a hose to the drain valve of your water heater and drain the water out of it into buckets or down a nearby drain. Once the tank is empty, we remove it by first disconnecting the water supply lines. If we have to cut them, we keep them as long as possible, which makes it easier to plumb in the new one.

05Install Your New Water Heater

Installing your new water heater starts with putting it in place and, if necessary, installing a new temperature and pressure (T&P) valve. We then plumb a discharge pipe into the T&P valve, which we’ll use to check the pressure after we’ve installed the water heater.

06Plumb and Brace Your New Water Heater

Next, it’s time to plumb your new water heater by connecting it to the rest of your system. To do this, we first connect the cold water and any necessary fittings using some plumber’s tape, which we wrap around the threads before twisting the fittings together. Since Charlotte, NC, requires seismic bracing for water heaters, we will then install seismic straps. These get attached to the upper and lower thirds of your hot water tank. Per building codes in North Carolina, the straps are anchored against wall studs, which, if the unit’s against a flat wall, will be about 32” apart.

07Fill Your New Water Heater

Once the tank has been plumbed and braced in place, we start the filling process by slowly turning on the cold water supply. At this time, we check the plumbing for leaks, and if there are none, we continue filling the tank.

08Flush Your Plumbing System and Do a Pressure Check

After the tank is full, we flush any air or debris out of the hot water plumbing system by running a nearby faucet for three minutes. Our electrician can wire your water heater and turn on the power if it’s electric. If you have a gas water heater, we can plumb the gas connection, turn on the valve, and test the system. After the water has been heated sufficiently, it’s time for us to check the discharge pipe. If there’s water running out of the T&P valve and into the discharge pipe, the pressure between the cold water intake and the tank is probably too high, so we’ll lower it to somewhere below 80 PSI.

What Should I Do If I Suspect My Water Heater Is Failing?

If you suspect your water heater is failing or notice signs that could indicate a problem, contact a professional technician immediately. A failing water heater can lead to a lack of hot water when you need it most, so addressing the issue quickly is crucial. Your technician will inspect the unit to diagnose and repair any problems or recommend a replacement if necessary.

What Should I Do if My Water Heater Stops Working?

If your water heater stops working, the first step is to ensure it’s properly connected and has power or gas supply. If it still doesn’t operate, contact a professional technician to diagnose and fix the issue. Timely service can prevent further damage and ensure your water heater is ready when you need it.

When should I call?Review the warning signs and common problems before booking.

How Do You Know You Need to Replace Your Water Heater?

The most common sign that you need to replace your water heater is that your water either doesn’t heat up at all or takes a long time to reach a warm enough temperature. This could be a sign that the heating element or the electrical or gas system that heats it has failed. You also might notice water leaking from your water heater. If this is the case, give us a call, and we can come check it out.

The first thing we’ll check is the plumbing to your water heater to make sure the leak isn’t coming from there.

How Do I Know If I Need a New Water Heater?

It can be challenging to determine if you need a new water heater, especially if the issues are minor or not immediately noticeable. However, signs such as inconsistent water temperature, reduced hot water supply, or strange noises from the unit could indicate that it’s time for a replacement.

What happens during service?See what the service involves and what to expect at your visit.

How Your New Water Heater Works

How does your water heater get the water it needs to warm up? Regardless of the type of water heater you have, it comes with an inlet that takes cold water from your supply line. Typically, this pipe would branch off your existing cold water supply, and we would connect it to your water heater. Once the cold water flows into your water heater, the heating elements inside heat it and store it inside the tank.

The back pressure from either your water supply or a pressure tank keeps the water in the heater’s tank at a pressure high enough to push it through the rest of the home. However, until a faucet, shower valve, or other valve gets turned on, the hot water stays inside your plumbing. Your hot water pipes, even with insulation, may feel warm to the touch.

Once you create negative pressure in the plumbing system by opening a valve, such as by turning on the hot water in your kitchen sink, the hot water in your tank and plumbing is pushed through the system out of the receptacle.

Repair or Replace Your Water Heater?

A loss of hot water does not always mean you need a new heater. Parks can inspect the unit and explain whether water heater repair or replacement makes sense. Compare the repair cost with the heater's age, condition, and history of breakdowns. Consider repair: A temperature-control problem or an isolated fault may be repairable when the rest of the system is in good condition.

Consider replacement: Frequent repairs, a corroded tank, or a unit that no longer meets your household's hot water needs are reasons to discuss a new system.

What Does Replacement Involve?

Parks checks the existing plumbing and connections, helps size the new unit, disconnects the old heater, and installs and connects the replacement. The installation includes filling the system and checking for leaks and proper operation. The step-by-step guide below explains the work in more detail.

Plan Your Water Heater Replacement

Water Heater Installation in Charlotte, NC The water heater installation and replacement process is unique, especially when it comes to plumbing your system and the water heater we install. The first step is to figure out the size heater you need and how we will plumb it so that it connects with your existing plumbing infrastructure. In some cases, you may not have plumbing already in place.

In this case, we could still choose the water heater that best fits your needs based on the size of your home, the number of occupants, typical water usage habits, and your energy conservation preferences. If you already have your plumbing infrastructure set up, connecting your water heater to it is relatively straightforward.

Typically, a home in the Charlotte, North Carolina, area has a single water heater that services the entire home. Plumbing this water heater involves connecting it to your hot water system. In some cases, a hot water system consists of a manifold that distributes hot water to the pipes that then continue to the fixtures in your home.

In other cases, you may have a single hot water supply pipe that comes from the water heater, and individual pipes branch off and take the water to each receptacle. Regardless of the setup your home has, your new water heater will plumb into your hot water supply line and ensure the rest of your home gets the hot water it needs.

How We Maximize the Efficiency of Your System

The above details are important because we use them to decide how to match your new water heater with your existing plumbing. For example, if you have especially long plumbing runs from your water heater to receptacles, it may be necessary to install a larger water heater that can make the system more efficient.

If, for instance, there’s a high ratio of water in your pipes to water in your water heater’s tank, your unit may have to work harder than it should. The unusually high volume of water in the pipes is constantly cooling down, so you may end up running your taps longer to get water that’s as warm as you’d like it to be.

This wastes water and forces your water heater to constantly take in more cold water, expending electricity or gas to heat it.
