Why Your Water Heater Might Not Be Keeping Up—and What to Do About It
Hot showers turning cold halfway through? It might not be your imagination—and it’s one of the most common calls we get from Lago Vista homeowners.
A water heater that’s not keeping up can be more than an inconvenience. It could be a sign of a deeper issue—and in some cases, a system that’s on its last legs. In this blog, we’ll break down the most likely causes and when to call a professional.
1. Sediment Buildup in the Tank
Over time, minerals in our Central Texas water supply can collect at the bottom of your tank, creating a layer of sediment. This layer acts like insulation, making it harder for your water heater to heat effectively.
Signs to watch for:
- Rumbling or popping sounds
- Slower recovery times
- Cloudy water
Solution: A professional flush or system cleaning can often restore performance.
2. Undersized Unit for Your Household
If your family has grown or your hot water usage has increased, your existing water heater might not be large enough to keep up. Most tanks are sized for 2–4 people—but usage varies based on appliances, schedules, and habits.
Solution: Upgrading to a larger tank or considering a tankless water heater may solve the issue permanently.
3. Thermostat Issues or Faulty Heating Elements
In electric models, broken or worn-out heating elements are a common culprit. For gas heaters, the thermostat or pilot light may be to blame.
Solution: Jarrod’s Plumbing can inspect and test the thermostat, heating elements, and other components—often replacing parts the same day.
4. The Unit Is Simply Too Old
Water heaters typically last 8–12 years. If yours is over a decade old and struggling, repairs might be a temporary fix.
Solution: A full replacement may be the most cost-effective and energy-efficient choice. Jarrod offers same-day replacements for homes in Lago Vista.
5. Plumbing Cross-Connections or Hidden Leaks
Less common but possible: incorrect plumbing layouts or hidden leaks can cause cold water to mix into your hot water line, making it seem like the water heater isn’t working correctly.
Solution: A licensed plumber can quickly diagnose layout issues or detect hidden slab leaks.
