"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"All the people sent to my home were professional, friendly and efficient. Eric, the repair tech, had to give me the bad news that my furnace was not repairable. He listened to my requirements and desires for the replacement and gave me a solution that matched at a reasonable cost. Novlin and Brandon came the next day to install the unit. They were careful of my home and floors. They installed the new furnace quickly and efficiently. They cleaned up after themselves very well. Before leaving, they showed me pictures of the work in the areas that I couldn't easily get to like the attic and roof. I'm very happy with the whole project"

"Albano's telephone response for our immediate service request was handled in a professional and helpful way.  The person dispatched a plumber to make the repair within a short time following the call.  He was professional, knowledgeable, and efficient.  I know being a plumber can be a dirty job, but the fellow just went to work in the mud and standing water to get the job done.  Interestingly, when I've had preset appointments, although they have always shown up on time, they often didn't have the parts the job required, even though the job was described to the call center I called into.  This visit was terrific!  All work was done in one trip, done well, and the price was decent.

Water Heaters FAQs, answered by experts

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

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.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.
