Water heater guides for Fullerton homes

How tank and tankless water heaters work, why they fail, and what hard water does to them. Each guide explains a problem in plain language, what you can safely check yourself, and when the job belongs to a licensed plumber.

  1. No hot water: what to check before you call a plumber A cold shower usually traces back to one of a few things: no flame, no power, a failed part or a heater that has simply reached the end. Here is how to narrow it down safely.
  2. A leaking water heater: where the water comes from matters Some water heater leaks are a loose fitting or a worn valve. Others mean the tank has corroded through. Finding the source tells you which kind you have.
  3. Repair or replace your water heater? Most water heater decisions come down to two facts: is the tank itself sound, and how far along is it in its life. Everything else is detail.
  4. Tank or tankless: choosing a water heater for a Fullerton home Both designs make hot water well. They differ in how they store it, how they are vented and fed with gas, and how much attention they need in hard water.
  5. Sediment, popping noises and flushing a tank water heater Minerals in hard water settle at the bottom of a tank. Over time that layer makes noise, wastes heat and shortens the heater's life. Flushing helps a sound tank; it cannot rescue a failing one.
  6. When the pilot light on a gas water heater will not stay lit A pilot that lights and then goes out is usually a safety device doing its job. The fix is often a small part, but the work involves gas and belongs with a licensed plumber.
  7. A dripping relief valve on your water heater The temperature and pressure relief valve is the last safety device between a malfunctioning heater and a dangerous one. When it drips, find out why instead of stopping the drip.
  8. Gas smells, venting and carbon monoxide around a water heater A gas water heater burns fuel and has to send its exhaust outdoors. When gas escapes or exhaust spills back into the house, it becomes a safety problem, not a comfort one.
  9. Seismic strapping for water heaters in California A full tank is heavy and top-heavy. In an earthquake, an unsecured heater can tip, tearing its gas and water connections. Straps keep it in place.
  10. Permits and code questions for a water heater replacement Replacing a water heater involves gas, venting, water pressure and earthquake safety. Permit and inspection rules are set by the city, so confirm them before work starts rather than after.
  11. Tankless water heaters: scale, flow problems and error codes A tankless unit heats water as it flows through a narrow heat exchanger. In hard water, minerals coat that exchanger, and the unit starts to complain.
  12. Electric water heaters: elements, thermostats and the high-limit switch Electric tanks have no flame and no vent, but they do have high-voltage parts behind their access panels. Most failures come down to an element or a thermostat.
  13. Rusty, discolored or rotten-egg hot water When hot water looks or smells wrong, the cause can be the water heater, the pipes, or a reaction inside the tank. A simple hot-versus-cold comparison narrows it down quickly.
  14. How to size a replacement water heater Bigger is not always better. The right size covers your busiest hour of hot water use, fits the space, and works with the gas or electrical service you already have.
  15. What drives the cost of a water heater replacement Two quotes for the same heater can look very different. Usually the difference is in the work around the heater, not the heater itself. This guide lists those factors without quoting prices.
  16. Hiring someone to repair or replace your water heater Water heater work involves gas, venting, high voltage and pressurized hot water. A few checks before you hire make it far more likely the job is done safely and to code.
