Additional service area - Cohasset, Fitchburg, Worcester, portions of Chelsea-Saugus, Chelmsford Counties. South Shore & Cape Cod and All of Rhode Island. Family owned and operated since 1984. Additional email - info@pioneerbasement.com. Additional phone - (800) 439-0788. Additional DBA - Pioneer Basement Waterproofing Inc.

"I had the estimate for the work done which went fine, then called to book the appointment. Was required to put down $200 for the $650 projected repair cost. I did this thinking there would be no issues between then and the repair date. My wife is quite pregnant and we had to move up the repair date to get the nursery ready in time for their birth. (twins) When I called to cancel this appointment and seek a refund of the $200, I was told that the window to cancel was 3 days from the scheduling and that I was forfeit my deposit. This information is in the contract, but I did not catch it at the time. I could only imagine if this were a bigger project and something like this happened to someone else. For the cost of $200 Pioneer Basement has not only lost me as a future customer, but forced my hand in posting several poor reviews such as this one. For any future customers, pay very close attention to this and hope "life" doesn't happen to you in between. Good luck."

FAQs for water heater installation and replacement projects in South-harwich, MA

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.
