"Tanous is the best HVAC company I've ever used (I've used several and wish I knew of them earlier). Johnny came to access and confirmed that I needed an entirely new system (as mine was 30 years old). He was very informative and knowledgeable about the process and the pricing was extremely reasonable than what I have been quoted in the past. The following day I spoke with Kris (also very kind and knowledgeable) and had us scheduled for an appointment the following week. Krisâ s team showed up on time, were very professional and efficient and replaced the entire furnace and central air in 1 day! I will only use Tanous going forward, they are the absolute best!"

"We have a smaller upstairs bathroom that had not been touched since 1975. The shower had been unusable for over a decade due to leakage. The space had to be completely gutted down to the studs and completely redone. The contractor we had used several times over the years retired, so we needed someone new who we could trust. Radical Renovations (Angelo) was recommended to us by N & S Supply in Kingston and I'm SO happy we hired him! He's professional, responsive, patient and finds solutions to all issues that invariably come up when you're dealing with old homes. Plus, the crew who he brought in to work with him was also pleasant and professional. I would absolutely hire Angelo again...in fact I already am!"

Total Plumbing offers a variety of plumbing services to meet your needs. Our family owned business guarantees your satisfaction. Services offered include, but are not limited to, hot water heater installation and repair, water softener installation, plumbing leak repairs, and new appliances and fixture installation. Contact us by phone, text, email, or the Angi app to schedule an appointment to service your plumbing needs.

"⭐️⭐️⭐️⭐️⭐️ Kevin at Total Plumbing is the absolute best! Our Navien combo system was acting up, and another company (T Webber) told us it needed to be replaced entirely—for $7,000—even though it was still under warranty and this fee was just for their labor! Thankfully, we called Kevin for a second opinion, and we’re so glad we did! Kevin quickly identified the real issue and assured us the unit didn’t need to be replaced, just repaired with a few new parts. He fixed everything for a fraction of the cost and saved us thousands of dollars. His honesty, expertise, and professionalism are unmatched. Thank you for being so reliable and trustworthy, Kevin! Highly recommend Total Plumbing to anyone in need of an honest and skilled plumber!"

FAQs for water heater installation and replacement projects in Harriman, NY

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.
