"Do not waste time with the big companies. I was quoted $2,700 - $3,700 labor and materials by one big company to replace my 40 gallon water heater and expansion tank depending on the life warranty of the water heater. I spent about $550 on materials and paid about $750 labor for this hardworking, local, power couple to install my water heater and expansion tank. They are trustworthy, reliable, provide long term maintenance instructions, and are good at communicating. Save $ and spend it on local people. By the way, Thomas & Galbraith did not leave this review."

"Zak showed up on time, looked at my to be fixed list and went right to work. He was able to loosen the shut-off valves in both bathroom sinks, so we we didn't have to replace those. (I'm 70 and arthritic, no strength in my hands and wrists.) If the shower regulator goes wonky again, I should be able to fix it myself as Zac showed me how. No charge for that fix. The toilet needed a new flapper-apparently the el crappo one I had used was no good-it was worth the $15 charge to finally not have to turn the water on/off to use the toilet! The cost of the project includes the new faucet which I guess to be $80-100 retail range (a nice Delta basic with sprayer). It was not a simple replumb; there were some challenges getting the old faucet out as parts were rusted and fused. Zac explained everything along the way, took care not to make a big mess and cleaned up after he was done. Took about 3 hours start to finish, including the time Zac took to go purchase the faucet and get the special tools needed to cut apart the old rusted parts. They will be coming back to install some shower rails for us after they get the parts. I will be calling these folks for any more plumbing repairs I need. I was so nice to call and actually talk to a live person and not play phone tag. I called them on a Thursday afternoon and they were here the next Monday morning as promised. This was a non-emergency call. BTW-they do charge $85 for a service call. This was work Plumb Tech originally did in December 2017. I had washed dishes in a dishpan and when I dumped the dishpan, water gushed all over the floor. I called they sent a tech over immediately-here in about 20 minutes. Turns out my old house and somewhat wobbley sink cabinet contribute to loosening the joints. The tech re-attached everything and tightened all the joints as much as possible. Everything is now working fine again. Done at no additional charge to me. I really need to have new cabinets installed so the sink will not move even a little, but the house is not worth that expense at this point. (We will be investigating some way of stabilizing things.) I really appreciate the fast response and not being charged."

"I canâ t say enough about the fantastic service I received from JV Plumbing! My water heater went out on a Wednesday night, and JV was there the very next day to replace it. The professionalism and attention to detail were top-notch, and they left the area spotless when they were done. The price was more than fair, which made an already great experience even better. Iâ m so impressed with their workâ JV Plumbing is definitely my go-to plumber from here on out!"

Water Heaters FAQs, answered by experts

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.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.
