"Robby not only helped me with a complete remodel of my bathroom but also replaced my hot water heater and made a new connection for a washing machine to be moved inside the house while turning the old connection, in an outside shed, into a much needed utility sink. All work was done in Jacksonville, FL at 3235 Hickorynut st. The bathroom remodel was on a very tight time schedule of 4 weeks and a complete gut job. Robby was an absolute professional and able to make the 4 week goal from start to finish. Pricing was very affordable for the remodel, new washing machine connection, utility sink install and hot water heater replacement. Always on time and great communication throughout the project. Call him with your project ideas and plumbing needs and you will not be disappointed. Highly recommend this plumber!"

"I called this plumbing company on a Saturday and Zef, the owner, and his employee installed our water heater that afternoon. They were polite and gave us excellent service. In fact, they picked up the water heater from Sears for us. I call that great customer service and will use them in the future."

"My husband and I were referred to CGC Water by close friends. Everything from the first appointment with the sales man to having the project complete felt very intentional and customer focused. They took water samples, listened to what we wanted, answered all of our questions (we had plenty) and set us up with everything we needed. I was really happy that they got us on the schedule quickly, we did not have to wait 4+ weeks that other projects have taken. The install was very thorough and even though nobody will see the equipment the install spot was left clean and the piping all looks nicely hung. That may not matter to everyone but I noticed. Before leaving, the technician made sure all equipment was working and retested the water to make sure it meets our expectations. Now we have a Kinetico whole house water softener, and a Kinetico RO drinking water system. I am so glad we went with the Kinetico system. I can tell a difference in everything! I dont get spots on the dishes anymore, my towels dont smell funky after washing them and having good water has even helped with dry skin. I love the drinking water too! I really can tell a difference from other drinking water and I always fill my water bottle up at home before leaving the house because other water just does not compare. I really appreciate the follow up as well, we opted for the scheduled salt deliveries and filter changes so we dont have to worry about it as much. I highly recommend CGC and the Kinetico water equipment."

Water Heaters FAQs, answered by experts

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.
