"I have had nothing but the best of experiences with Wisler each of the 3 times I have communicated with them while troubleshooting my 50 gallon power vented gas water heater. The technicians they sent to our house were the most clean, courteous, patient and honest technicians that I have had in my home for any service related work. They diagnosed my problem and gave me my options and a written quote for those options. The only concern I had with hiring them for the replacement on the 1st visit was cost. Their quality service so far has exceeded my cost concerns. In the end I decided to buy my own water heater and have them install it. I did cost comparisons for this service and they are definitely within the market norm. They installed my water heater within 2 1/2 hours. They left my house neater than it was before they came. They professionally answered all my questions and explained what they did after they were done. I ended up signing up for their annual service check up plan. The service is reasonably priced and includes the flush that I know I wouldn't do otherwise. I will hire Wisler for my future plumbing needs."

"The technician responded to a Sunday morning call to check on a lack of water coming into the house by arriving later that afternoon.  He then spent two hours testing the switch, guage and tank on the well.  When nothing conclusive was determined, he said he would return later in the week to measure the depth of the well, thinking that perhaps it had run out of water or that the pump wasn't low enough.  He returned on Thursday as scheduled, tested the water depth without pulling the pump, thereby saving me at least $700, and then found a problem in the toilet.  He addressed that and gave me some dye to use to test for further leaks in the toilet.  He suggested I put a low-water cut-off switch on the well pump and I agreed.  When he called later to schedule that job, I told him I had changed my mind, but he came by anyway to check on the toilet.  In all he spent about 6 hours at the house, talked me through each test he performed and made recommendations as to how to deal with the situation in the long term."

"Chris, Luis and Travis were great!They were easy to reach and quick to visit us (despite our post-snowstorm driveway conditions). They all communicate well and ensure an understanding on both sides every step of the way. Travis and a colleague were both courteous while in our home and did a nice, clean install of a new water softener and sediment filter. We’re very happy with the service we received so highly recommend Plumbing Champions!"

"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, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

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.
