Electric Water Heater Repair & Installation in Holly Springs, GA

Once the decision to replace an electric water heater is made, the installation itself tends to raise practical questions: how long the water is off, what the installer needs from you, and what you should check afterward. When Alpha Plumbing and Sewer replaces a heater in Holly Springs, the day follows a predictable rhythm.

Before the installer arrives

Clear the area around the heater and the path to the door. Move vehicles if the heater is in the garage, and put pets somewhere quiet. Know where the breaker panel is. If the house has a single main shutoff and nobody knows where it is, mention that when you book, because the installer may need it if the heater's own valve does not hold.

Getting the old tank out

The breaker is switched off and checked with a meter, and the cold supply to the heater is closed. Draining comes next and is often the slowest part, since sediment in an older tank can clog the drain valve and slow the flow to a trickle. Once empty, the water lines and the electrical connection in the junction box on top are taken apart. An empty tank is still awkward to carry, so floors and stairs along the way get protected, and hauling the old heater away should be spelled out in the agreed scope.

Connecting the new heater

The new tank goes into position, in a drain pan where a leak would reach finished space. Water connections are made with new connectors; where copper pipe meets the steel fittings on the tank, dielectric fittings help limit galvanic corrosion, and many heaters come with them. A working shutoff valve on the cold side is part of a proper installation. The relief valve that ships with the heater is installed or checked, and its discharge pipe is run to a safe place. Where a check valve or regulator at the main closes off the plumbing, an expansion tank is added so heated water has room to expand. The existing circuit is then connected in the junction box, provided the new heater's voltage and wattage match it.

The first fill and the first heat

With a hot tap open somewhere in the house, the cold supply is opened and the tank fills. Air sputters out of the tap until water runs steadily, which shows the tank is full and the elements are submerged. Only then is the breaker switched back on. The thermostats are set, the joints are checked for drips, and the heater starts its first heating cycle. A full tank of cold water takes a while to reach temperature on an electric heater, so plan on hot showers later in the day.

What you should be shown before the installer leaves

• Where the heater's breaker is and how to switch it off.
• The cold-water shutoff valve on the heater.
• The relief valve, its discharge pipe and what it means if water appears there.
• The drain valve, for future flushing.
• The thermostat setting that was used.

Keep the paperwork with the model and serial number, and register the heater if the manufacturer's warranty requires it. Check the connections again the next day for any slow drip.

Holly Springs permit requirements

Holly Springs' code calls for a permit from the building official before plumbing covered by the construction codes is installed, altered, repaired or replaced. The city's Community Development Department handles building permits and can confirm what a heater replacement at your address needs.

Questions about installation day in Holly Springs

How long will we be without hot water?

From the moment the old tank is drained until the new one has finished its first heating cycle. Draining an old tank can be slow, and a fresh electric tank takes a while to heat a full load of cold water. Many households plan around it by showering the night before and saving laundry for the next day.

Why does an expansion tank get added sometimes?

Water expands as it heats. In a house with a check valve or pressure-reducing valve on the main, that extra volume cannot flow back to the street, so pressure rises with every heating cycle. An expansion tank gives it somewhere to go, which protects the relief valve and the heater. Testing house pressure is part of water pressure and PRV service.

Can a new heater go in the same spot as the old one?

Usually, if the new model fits the space and the circuit. Current tanks can be wider or taller than older ones of the same capacity, so measurements come first. Switching to a gas water heater instead changes the venting and fuel work. Alpha's water heater overview lays out the alternatives.
