Why does it seem that the worst plumbing or air conditioning problems happen when you least expect it? Your AC fails in the middle of a record heat wave, you find a water leak right as you're leaving for vacation, or your heater stops working in the dead of winter. Whether you need routine maintenance to prevent such issues in the first place, or a trusted technician to handle a plumbing or air conditioning emergency, you can trust the team at Five Star Plumbing Heating Cooling.

"Today I experienced the worst encounter with 5 star heating plumbing in air.The technician that came out was incompetent confused he told me thar my control damper motor was bad the other was good and my zone control board was good .... In which to replace a control damper motor is not as much as of a hundred or two hundred dollars then he tells me because they don't carry the honeywell motor that I would have to replace my entire system and it will cost me $4279.....this must be a scam....please beware"

"I made an appt with them for Wednesday from noon to 2. They no showed and didn’t bother to call. I called back Friday and they agreed to come out right then. However, the truck didn’t have enough to pump my entire septic and they said they would come out first thing Monday. They no showed again on Monday. Four days later they tried to contact me to reschedule. I refused at that point. I can’t be kept waiting for 2 weeks for whenever they feel it is convenient for them…if you make an appt, keep it!"

FAQs for water heater installation and replacement projects in Clemson, SC

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.
