"I overfilled my garbage disposer!! My sink had 2 inches of water as a result of my trying a plunger to clear it. I called RS Plumbing at 4:45 in the afternoon and Steve came the next morning at 8:00.

He had me clear the area around the basement pipes in case the clog was more major than I hoped. He was able to clear the drain only in the kitchen area. He worked efficiently and had the drain running freely. I asked him to check the dishwasher hosing in case that was part of the blockage. I have had problems with that before.

RS Plumbing was prompt, competent, and overall good to work with."

"If I could give 10 stars, I would. My water heater started spewing out water at 5PM on an unsuspecting Wednesday evening. I called several local businesses that offered â 24 hourâ service, with no luck coming out that evening. However, I received a call around 7PM from Adam Langridge, the owner of Otter Plumber. He said he would be able to come out to my house by 8PM, which he did. He took a look at the water heater, and he said that I needed it replaced, which did not come as a big surprise considering the unit was over 12 years old. We discussed what options I had, and how to proceed with the replacement. Ultimately, I purchased a brand-new water heater the following day from a local hardware store, and he said that he would go pick it up and would install it the same day. He didnâ t even charge me for the evening house call. He picked up the unit in the afternoon, the following day, and installed the unit within 2 hours, having everything finished by 5PM. From start to finish, it took less than 24 hours to get a new water heater replaced!!! You cannot find a more reliable and efficient worker!!! I would hire Adam 10 out of 10 times without thinking about it twice. Thank you Otter!!!"

Water Heaters questions, answered by experts

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.
