"Intrepid did an incredible job in a time that we really had an emergency. They had our water heater diagnosed and replaced luckily within 24 hours. On top of the urgency that we needed a replacement, the price was really fair. Robert did a great job and was very friendly and professional while working at my house. They left no mess and removed the old water heater. 10/10 would use again"

"Exceptional Service from Kelsey Asrouch – Highly Recommended! We had the pleasure of working with Kelsey Asrouch, a plumber from Hart’s Services, and the experience was outstanding from start to finish. Kelsey installed three new toilets and cleared a stubborn clog in our kitchen sink air gap—and he did it all with incredible professionalism and skill. He arrived right on time, fully prepared, and walked us through everything he was going to do. His attention to detail was impressive, and he made sure everything was functioning perfectly before he wrapped up. On top of that, he left the work areas spotless—you’d never know a major plumbing job had just taken place.

"This was a simple hose leak under kitchen sink. Plumber made an appointment on Saturday between 10 and 12 and did not show up on time, without giving notice. After calls from me, he eventually made it in over an hour late. At that point, he did not do anything - he said he needed to custom order a sprayer hose and will call me Monday with pricing and to schedule. Today it's Friday, leak still going under sink, and still no call, despite messages left to him. My tenant is very irritated, and I am hiring someone else."

FAQs for water heater installation and replacement projects in Seattle, WA

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.
