Water Heater Repair & Installation
Overview
What to expect
Few things disrupt a household faster than losing hot water. Whether your heater is leaking, running cold, making popping noises, or simply old and inefficient, MainLine Plumbing's licensed plumbers diagnose the problem and give you straight answers, repair or replace, with the honest math behind each option.
We service and install every major brand of both tank and tankless systems. Common repairs include burnt-out elements, thermostats, thermocouples, pilot assemblies, anode rods, and pressure-relief valves, and our trucks are stocked so most fixes happen on the first visit. When replacement makes more sense, we'll size the new unit to your household's real demand, handle the permit and code requirements, haul away the old tank, and register your manufacturer warranty.
A leaking tank is more than a nuisance, it can flood a garage or closet, so we treat it with urgency and often complete same-day installations. With upfront, flat-rate pricing and financing available on new systems, upgrading to a reliable, efficient heater is easier than you'd expect, and you'll know the full price before we touch a thing.

FAQ
Water Heater Repair & Installation questions, answered
Should I repair or replace my water heater?
If your unit is under 8-10 years old and the repair is minor, fixing it usually makes sense. Once a tank heater passes 10-12 years, leaks, or needs a major part, replacement is typically the smarter long-term move. We'll give you the honest numbers either way.
Can you install a water heater the same day?
In most cases, yes, especially for a like-for-like tank replacement. Tankless conversions or jobs that need gas, venting, or electrical upgrades may take a little longer, and we'll tell you upfront when scheduling.
Is a tankless water heater worth it?
Tankless units deliver endless hot water and save space, and they often last longer and use less energy. The upfront cost is higher, so we'll walk you through the payback and whether your home's gas or electrical setup is a good fit.
Why is my water heater leaking?
It could be a faulty pressure-relief valve, loose connections, or, most seriously, a corroded tank. A leaking tank can't be repaired and should be replaced quickly to avoid water damage. We'll diagnose the source before recommending anything.

Real Reviews
Trusted by Columbus Homeowners
Woke up to water pouring through the kitchen ceiling at 2am. MainLine had a plumber out within the hour, found the failed supply line, and stopped the damage fast. Lifesavers, and the price was exactly what they quoted.
Maria T.
Riverside
Our water heater died right before a houseful of guests. They installed a new one the same day, walked me through the warranty, and left the garage cleaner than they found it. Couldn't ask for more.
James K.
Oakwood Heights
Got three quotes to repipe our old house. MainLine was the most transparent about the scope and the only one who gave me a flat price in writing. Two years later, not a single issue.
