"I was out of the country for a few weeks and came home to a heavily leaking water heater. Went to the box store first and trusted my instinct to not have them 'send a guy'. i wanted a real licensed plumber to review this and am really glad I did. Mike came out the next day and had my new water heater installed before noon, plus answered my questions on several other projects. I highly recommend this company."

"Set up appointment to observe issues with my water softener.  Employee from American Pure Water was very professional-showed me the issues and offered several options to purchase new or to repair old.  Showed me several options of new softeners with description of all shared with me . No pushy sales at all!!  Made decision  to purchase.  The following Saturday employee from American Pure Water arrived to install new water softener and hauled my old one away. Within forty five minutes I had a new softener installed and understood how all functions and what I need to do (if needed).   Throughout entire process employees were friendly, professional, not pushy, offered many options, seemed to have much knowledge and strong belief of their products. On time for both appointments-no waiting around.  Highly recommend American Pure Water to anyone searching or just wanting information on water softeners, drinking water systems, air purification, needed salt delivery, or in need of iron &/or sulfur removal.  As they state, "We have what you are looking for!"

"When Dave arrived and looked at the faucet and where it was located - he told me that it would be an additional $50 to cut a hole in the drywall which I said ok.  Then he went down to the basement to look for the water connection and he noticed that I had an old disconnected water softener.   He mentioned to me to me that I should have this water softener removed because it should be  because it potentially could cause an explosion.  Then he replaced the faucet and I asked him to give me an estimate on a 50gal new hot water heater and he did, gave me a written estimate and said that they would replace all the connections and hookups and I thought the estimate was totally fare.  Then as he was leaving, he said that he was not going to charge me for the cut into the drywall, and I was most appreciative.   He did a great job and I will definitely have him come back again.

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

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.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
