A clear, professional approach to water heater replacement — tailored to your St. Marys property.
Our St. Marys plumber assesses your household hot water usage, existing gas or electrical infrastructure, available space, and budget to recommend the best replacement water heater for your specific situation.
Magnet Plumbing removes your old water heater in St. Marys, PA carefully — draining the tank, disconnecting all utilities safely, and hauling the unit away. We inspect the installation area for any issues that should be addressed before the new unit is installed.
We install the new water heater with all required connections — supply and hot lines, gas or electrical, T&P relief valve and discharge tube, expansion tank where required, and proper venting or condensate drain.
Our St. Marys plumber fills the new water heater, starts it up, and monitors the first heating cycle. We check every connection for leaks, verify proper temperature output at fixtures, and walk you through the controls and maintenance schedule.
Answers to frequently asked water heater replacement questions from St. Marys homeowners.
Replace your water heater in St. Marys when it is over 10 to 12 years old, produces rusty or discolored water indicating internal corrosion, leaks from the tank body, requires frequent repairs, or no longer meets your household hot water demand. A water heater approaching these conditions often fails unexpectedly — replacement before failure avoids an emergency.
Most St. Marys jurisdictions in PA require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for St. Marys water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
For a tank water heater, the right size depends on the number of occupants: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, and 50 to 80 gallons for larger households. For tankless units, the required flow rate in GPM determines the correct unit size. Magnet Plumbing assesses your household demand and recommends the right unit for your St. Marys home.
Tank water heaters cost less upfront and are simpler to install. Tankless units provide endless hot water on demand and typically have lower operating costs, but cost more initially. For most St. Marys families, a quality tank unit in the correct size is the most cost-effective choice. Our plumbers help you compare the total cost of ownership for your specific situation.
Our reputation is built on results. Here is what our customers have to say.
"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."
