"Dave and AJ from Freedom Contracting & Excavating did a great job for a reasonable price. I had an idea for an outdoor griddle setup using natural gas instead of propane tanks. I thought it was a long shot but they were able to make it happen. Very courteous and straight forward. They even went above and beyond by helping me with the natural gas conversion on my griddle. I would definitely hire them again and if you need any gas line work done, call Freedom C & E for sure! Thanks again!"

"I contacted the owner on March 28 to have him bid on the drain waste vent installation for my new construction. The owner came out the following day. He gave me a bid on the spot. He offered a fair price. He recognized me for my military service and I had a good vibe about him so I accepted his offer on the spot. I had appointments scheduled with two additional plumbers that I cancelled upon accepting the owner's proposal. The owner agreed to complete the work the week of March 31. I followed up on April 3 and again on April 6. On April 7, he responded committing to arrive the morning on April 8. I'm 128 miles round trip from the build site. The owner did not show up. After finally reaching him, he promised to be out by 11:30. A worker showed up by himself at 4:30 and said the job was too big for him alone. It is near the end of May and the owner continues to string me along with false commitments. It is clear now that he has no intention of following through with our contract. "

Reliant gas lines is a natural gas service line repair or replacement company. I handle the buried portion of the service line from curb stop to meter and the buried house line if the meter is far away from the house. I do a good job at a fair price, am qualified for both Peoples Gas and Columbia Gas and fully insured. As a small owner operator business I can be flexible on scheduling as these types of problems tend to be emergencies. While in business for myself just a short time now I have over 15 years of experience in the natural gas industry involving repair and replacement of gas mains and service lines.

"Reliant Gas Lines arrived at my house quickly. They made all the repairs fast and efficiently. Matt and his crew were very respectful of me and my property. I would not hesitate to hire them again. Very highly recommended."

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.
