"I've been using this company off and on for several years. They aren't the least expensive, but I'll tell you, they are the best! I have a vacation rental and a sump pump...not a good combination. Last night, the guest reported sewage backing into the shower and bathtub. I got in touch with Beverly at 8 a.m., and she had someone at the house by 9:30. Beverly has always taken my calls these past few years, and she feels like a family member who is there to help. She is always helpful and talks me off a ledge when I'm stressed about a plumbing issue. Thank you, Beverly! Ryan was my service tech, and, like all their staff, he was prompt, courteous, and professional. He informed me about each step and took pictures to show me what the problem was and the resolution. He handled a disgusting job that almost all people would not touch. They resolved my issue, and my current guest was very happy. Thanks for digging out all the grease that prior guests have dumped down the sink. Not a good combo with the sump pump and plumbing. Happy Holidays to all!"

"I cannot say enough about Aaron Schwarder and Schwarder Construction. We bought a home that had not been updated since 1964. Plumbing included. Aarons crews redid both baths and the kitchen. Beautiful bright Carrera look tile, white counter tops, beadboard, wainscoting. New light and plumbing fixtures. Kitchen went from dark and cave like with fluorescent lights in plexiglass recessed ceiling thing, to raised ceiling, high end appliances, beadboard cabinets and an open to the dining room floor plan. Aaron was not satisfied with the cabinet surfaces and repainted them himself. All custom cabinets. Very important to me is the comfort level of having people working in my home. It can be awkward, to say the least. Aaron's guys are very respectful and always clean up at the end of the day, even if they are coming back in the morning. They were very careful not to let the animals escape. Recently I called the home depot pro desk with some questions about installing a new entry door and the first name they gave me was Schwarder Construction. I was raised to believe that a man's word is his worth. You can take Aaron at his word. 5 stars only because you cannot rate higher."

FAQs for water heater installation and replacement projects in Flagstaff, AZ
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.
