Question 1 of 4
How old is your water heater?
A rough guess is fine. If there's a sticker on the tank, the date is usually in the serial number.
Question 2 of 4
What kind is it?
A tank is the tall cylinder in a closet or garage. Tankless is a box on the wall.
Question 3 of 4
Has it ever been flushed, or had the anode rod replaced?
Most people have never been told this is a thing. "No" and "not sure" are the normal answers.
Question 4 of 4
Noticing any of these?
Choose as many as apply, or tell us nothing's wrong.
Your result
Phoenix water runs 172-302 ppm total hardness - 10 to 17.6 grains per gallon - per the City of Phoenix 2025 water quality report. Tank heaters are generally rated 8-12 years; in very hard water an untreated tank may last 5-7. Anode rods are sacrificial and last 3-5 years, less here.
