Hard water and your water heater
West Texas water is hard, and San Angelo is no exception. Minerals settle at the bottom of a tank water heater as scale. That layer makes the heater work harder, can cause popping or rumbling noises, and shortens its life.
Flushing a tank once a year removes much of that sediment. Tankless water heaters are affected too: scale builds up in the heat exchanger, so most makers recommend descaling them regularly in hard-water areas.
Signs it's time to replace
Most tank water heaters last somewhere around 8 to 12 years. Rusty or discolored hot water, water pooling around the base, a tank that runs out of hot water much faster than it used to, or loud rumbling are common signs that the end is near.
A leak from the tank itself can't be repaired, but a leak from a fitting, valve or connection often can. Have a plumber check before you assume you need a new heater.
Safety checks that matter
Every tank water heater has a temperature and pressure relief valve, which lets out water if the tank gets too hot or the pressure too high. If it drips or has been capped, have it checked: it's the main safety device on the tank.
Gas water heaters need a clear, working vent so exhaust leaves the house. A carbon monoxide alarm near sleeping areas is a good idea in any home with gas appliances.
Before you replace it
Texas licenses plumbers at the state level, and installing a water heater is plumbing work. Ask for the plumber's license number, and ask whether a city permit is needed for your job.

Questions
How often should I flush my water heater in San Angelo?
Once a year is a good rule with hard water. If your tank has never been flushed and is several years old, ask a plumber to do it, since old sediment can clog the drain valve.
Is tankless better with hard water?
Tankless heaters work well but need regular descaling in hard-water areas like San Angelo. Some homeowners add a water softener to protect both the heater and the plumbing.
Can a leaking water heater be repaired?
If the leak is from a valve, fitting or connection, often yes. If the tank itself is leaking, it needs to be replaced.
