"I purchased a Generac standby generator from AirSouth in July of 2022. I was assured that this standby generator would power my home in the invent of a power outage. When the generator was installed, there was a problem with this brand-new generator, and they had to order a new main board because the generator was not charging. I was concerned about this, but the generator had a five-year warranty, and they explain sometime equipment have bad parts. AirSouth assure me that they would do regular maintenance to make sure this generator was performing as expected. WHICH THEY DID NOT DO! The first time we experienced a power outage was on Friday 06/16/23 the generator came on for about one and half hours and shut off. I called AirSouth and they sent a technician out that spent about 25 minutes out here and told my husband that the main board had went out and they would have to order one and it would not be in until Tuesday 06/20/23. I paid 13,822 for a backup generator that did not work the first time it was needed. When I called AirSouth to ask to speak to a manager or someone in charge I was told they were on another call and was not able to take my call. I than explained to Denise that I would not allow any repairs to this generator, and I needed them to replace it because obviously there is a defect with this generator if the generator requires three main boards in less than a year. She explained to me that they would only be able to repair this unit not replace it. AirSouth showed no concern for me or my family after I had paid them for this generator. I only make about 40,000 a year so this was a huge investment for me. They were total unconcerned that this was a brand new system that had never been use. They seem to think it was ok that I would have to wait four days during a power outage to use a generator that I paid them to install and had never had cause to use. Right now, I am feeling as through I have been scammed because I made the decision to invest this large amount of money for the security of my family and when the power went out, we were in the same position as everyone else, no power. My husband had to go and pay $400 for a portable generator to get us through the weekend. Bad business!! This was the perfect opportunity for the advertisement of not only Generac but also AirSouth due to the fact everyone in the area was hot and frustrated. My family, friends and I'm sure my neighbors were aware that I had recently had the Generac installed, and because AirSouth do the huge advertisement on their vehicles they were aware of who did the install. Epic failure, because when the power went out, everyone witness the fact that after paying for this generator I was still in the same situation as everyone else, NO POWER! I should have just stayed with the portable generator. It would have be much, much cheaper! A week later and they are still making excuses."

Water heater installations and replacements FAQs
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.
