Water Heater Installation & Repair in Conway SC
Conway homeowners typically call this category for one of three reasons: the tank is leaking or no longer heating water, an old unit needs replacing before it fails, or a new install requires upgrading to a tankless system or a larger tank. The work covers diagnosing failed elements, thermostats, or heating coils, flushing sediment out of tanks, replacing anode rods, and full swaps of gas or electric water heaters, including venting, gas line, and code-required updates like expansion tanks or drain pans. We list 22 businesses in and around Conway that handle this work, ranging from small owner-operated plumbing outfits to larger service companies.
What to look for before you hire
A good water heater job starts with an accurate diagnosis, not an automatic push to replace. Ask whether the company pulls permits for full installs (most municipalities require this for gas and electric units), whether they carry the licensing SC requires for plumbing work, and whether they warranty both labor and parts separately from the manufacturer's tank warranty. For replacements, get the sizing right: a unit that's too small means cold showers, too large wastes energy. Straightforward tank swaps in Conway usually run a few hours; tankless conversions take longer because of venting and gas line changes.

Common questions about water heater installation & repair
- How much does water heater installation cost in Conway, SC?
- A standard 40-50 gallon electric or gas tank replacement typically runs in the range of a few hundred dollars for labor plus the cost of the unit, though older homes needing code upgrades (expansion tanks, new shutoff valves, updated venting) push the total higher. Tankless installations cost more upfront due to gas line and venting work.
- How long does a water heater last, and when should I replace instead of repair?
- Most tank water heaters last 8 to 12 years. If yours is past that age and showing rust-colored water, popping noises from sediment buildup, or a leaking tank, replacement is usually more cost-effective than repair. A failed heating element or thermostat on a newer unit is often worth fixing.
- What should I expect on installation day?
- Expect the old unit drained and removed, the area checked for code issues (drain pan, expansion tank, venting), and the new unit set, connected, and tested for leaks and proper temperature. A straightforward swap usually takes 2 to 4 hours; jobs needing electrical or gas line changes take longer.
- How can I tell if a plumber did quality work on a water heater install?
- Check that the temperature and pressure relief valve has a properly routed discharge pipe, that connections show no signs of leaking after a day or two of use, and that they left you with the permit and any warranty paperwork for both the unit and their labor.
