"The technician was supposed to be doing a plumbing inspection and draining the water heater. My wife was home; the guy was at my place for a total of 20 minutes and did not say much, then left. I wanted to talk with him about what he saw and some possible things to work on, but he just gave my wife the invoice and left. I am not an expert in any way, but I would think it would take more than 10 minutes to drain and inspect the water heater alone. But I would not know since I was unable to speak with him."

"We needed all the pipes replaced in our house. We also switched to a tankless water heater. Dustin came to give us an estimate and advise when they could start the project. We had gotten a couple of estimates but something just felt different with them. We liked that we received an email with who would be coming to give us an estimate as well as a picture of the technician we should expect. It was so refreshing working with this company it reminded me of company's 50 years ago with values and a caring staff. Dustin, Mike and Anatoily had what I will refer to as the three P's. They were professional, punctual and personable. They laid drop cloths and cleaned up everyday after themselves. They even finished the job a day early than projected as we were scheduled to go out of town for five days. I would highly recommend Honest Sewer & Drain. By the other positive reviews you guys are doing a fantastic job. Keep up the good work and it was a real pleasure doing business with you."

"Jason P, the plumber, showed up the first day to inspect the job-did a test to show the re-circulator (14 years old) was not working---needed a part that had to be ordered and returned to complete the job the next day-left the work area spotless, was very cordial and knowledgable--explained to me the cost options of different hot water re-circulators so I could make an informed decision--job cost what was quoted--was on time both days--very satisfied w/the service...

Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer.  This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

Water Heaters questions, answered by experts

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

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.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

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.
