"I was looking for a pro who was experienced, honest and could communicate to get the job done right. Dave was the man. He knew what I wanted and suggested options to give the project(complete kitchen and bath remodel) a 5 star review. After my rental was completely destroyed from a tenant, I was up a creek without a paddle. Dave and Pablo went above and beyond to create the Reno I was looking for. From the first interview to the end result, I have no reservations for recommending ModernKnight for any project. They were on time , completely transparent and accommodating every step of the way. Are you looking for the pro to get your job done? Look no further, Dave is the guy! Thanks again Dave and Pablo for everything and more! Freddy."

General contractor here to help you with all your construction needs such as repairs, remodeling, roofing and more

"2 bathrooms 90% gutted from water damage. Cement board, Drywall and tile were replaced. Installed new shower doors in both bathrooms. Reinstalled toilets and sinks. Paint. Also kitchen, dining room and living room were painted. All furniture was moved and covered when painting. The crew worked clean inside the house and cleaned up every time they were done for the day, I was a little messy outside but not horrible. The entire crew was very easy to work with and answered all questions we had. They showed up for work every time they said they were going to.The job took about 4.5 weeks."

FAQs for water heater installation and replacement projects in Sparta, NJ

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.
