Irving’s permit for a new water heater
Irving’s residential guidelines do not require a permit for replacing fixtures or appliances at their existing connections, except water heaters, so a new heater goes through the city. The permit is one of those that need no plans, and the application is made through the city’s online portal.
Occupations Code 1301.551 has each Texas city above 5,000 residents govern water heaters through its own ordinance, with a permit needed ahead of any plumbing; the exceptions are leak repairs and replacing a water closet, a garbage disposal, lavatory or kitchen faucets, or ballcocks or water control valves.
Behind any plumber you hire in Texas stands a Responsible Master Plumber, who carries the liability insurance the state requires and is the one who obtains permits and requests inspections.
Getting the size right
Tanks are sized by first-hour rating: the hot water delivered in one busy hour. How many people live in the house and which hot-water uses overlap set it, and the water heater size calculator turns those answers into a tank size.
For a tankless unit in Irving, the tankless flow calculator takes a 36°F January low to mean 52°F incoming water, so reaching 120°F is a 68°F rise. The answer comes as gallons per minute instead of a tank size.
Reading a water heater’s age
A water heater’s serial number holds its build year. Choose the brand in the water heater serial number decoder before typing the number, since identical digits mean different things on different labels; the result is a year and an age to weigh when repair and replacement are close calls.
A water heater leak can lead to leak detection, a whole-house water line job leads to repiping, and the homepage lists all seven services together.
