FAQs

Water Heater Questions? We Have Answers.

Straight from our expert plumbers — everything you need to know before you call.

Generally, tank water heaters last 8–12 years, with an average of about 10 years. Quality of installation, usage frequency, water quality, and maintenance all affect lifespan. Tankless models can last 15–20 years with proper care.
It's strongly recommended to replace water heaters in finished spaces before they fail and cause damage. Planning ahead lets you compare energy-efficient models and avoid emergency service fees. If your unit is 10+ years old and requires frequent repairs, replacement is usually the wiser investment.
Common causes include a tripped circuit breaker, faulty heating elements, a blown fuse, or a failed thermostat. For gas models, a pilot light issue or gas supply problem may be the culprit. Contact our experts for an accurate diagnosis.
While a tankless water heater offers endless hot water, other options include adding a second tank, upgrading to a larger tank, or installing a tank booster on your existing unit. Each has advantages — our plumbers will walk you through the best choice for your home and budget.
A tankless system can be wall-mounted and takes up to 60% less space than a traditional tank water heater — ideal if your utility room or basement is tight on space.
Annual maintenance typically includes flushing the tank to remove sediment, checking the anode rod, inspecting the pressure relief valve, and checking for leaks or corrosion. Regular maintenance extends lifespan and keeps efficiency high.
The water shut-off valve is typically on the cold inlet at the top right of the tank. Turn it to the off position, then shut off the gas or power. In an emergency, call Day & Nite's 24/7 line at (425) 224-6452 — we'll walk you through it.
Most manufacturers offer a warranty lookup tool using your serial number. Day & Nite also backs every installation with a lifetime workmanship guarantee through our Red Carpet Service program — so you're double-covered.
