American Kitchen and Bath, Inc. is a reputable full-service General Contracting business based out of San Jose, CA. We specialize in kitchen and bathroom remodeling. We not only design your kitchen and bathroom, we handle the entire project while offering innovative ideas and creative design solutions. Contractor's License #886059
"American Kitchen and Bath, Inc. completed my contracted improvements on time and within budget. And that’s what would be expected. Yes, I would recommend them. AKB went beyond the normal expectations. My project required a whole house renovation. It included replacing the electrical, plumbing, windows, flooring and interior and exterior paint along with a completely new kitchen and bathroom. I found AKB by reviewing the City of San Jose permit website and saw they had pulled more permits than other local firms listed in National Association of Remodeling Industry (NARI). I completed an online contact request, and Shawn responded within the hour. We made an appointment to discuss what I wanted and was assured they could do the work within the budget. The process of developing the scope of work was very detailed. There were a few subcontractors necessary for my project, and I was introduced to each contractor at this early stage. I could tell from these meetings that the contractors had a very good relationship with AKB. It also involved working very closely with their designer, Buffy. I had no vision as to what I wanted, but Buffy was able to tease out what I did not like. In no time, she knew exactly what would appeal to my taste. Both Shawn and Buffy remained part of my project all the way through to the finish. When the project started, the demolition, installing a beam, rough plumbing and electrical all moved along very quickly. We were scheduled for the first city inspection when the pandemic shelter-in-place order was given. I was reassured by Johans, the owner, that the minute the business was released from the shutdown, my project would proceed. After the shutdown and passing that first inspection, the work progressed at an amazing rate. The site supervisor, Ron, would save up all of his questions for our Friday meetings as well as email or texting which would allow me to make necessary decisions quickly. They made sure that every decision I made was followed. There was a great deal of plaster and drywall patching, interior and exterior trim work, refinishing of doors, and many other finishing touches that needed to be done. Ron made sure each detail was completed with care and craftsmanship. The quality of the work was exceptional. All AKB employees and subcontractors were very responsive and respectful of my house as well as my time. At the first meeting with Buffy at my house, she called my house a “gem.” The finished project is better than I could imagine. I was promised a new beautiful home and now have my dream home, my gem."

FAQs for water heater installation and replacement projects in San Jose, CA
You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.
For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.
Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.
Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.
A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
