Common Water Heater Issues

Your water heater should last 12-15 years if treated properly. But, problems can appear at any time, even if the heater is fairly new. At All City Plumbers, we offer expert water heater services in Northridge, CA. We’ve identified three common issues people often see with their home water heaters.

If you see any of the following three problems with your water heater, make sure you address them immediately. If the problem gets worse, call one of our professionals for water heater repair in Northridge, CA.

Waiting to fix a water heater can lead to a complete breakdown of the unit! This is unnecessarily expensive and totally avoidable.

1. Discolored water and bad taste

This is a sign of danger. If your hot water is coming out brown, rust-colored, or has a strange odor (sometimes like sulfur) or tastes bad, you have a problem.

The discoloration is due to the accumulation of sediment and rust in the unit’s tank. You will have to empty the entire tank and clean it. If you are not sure how to do it, hire a plumber in Northridge, CA.

If the water tastes or smells bad, you probably have a buildup of bacteria in the tank. This is dangerous to your health and can make your family sick.

The tank needs to be bleached and cleaned. It is almost always better to have a professional do this. Our team can clean and disinfect the tank so that you get clean water for your showers, for washing your dishes, cooking, and even for drinking.

Whether you have a traditional water heater or a  tankless water heater in Northridge, CA, we can solve your problem quickly and efficiently

2. Low hot water pressure

If you are receiving low pressure from hot water, there are several problems. The faucet stem may be clogged with sediment.

Is the supply line clogged or leaking? The faucet may be clogged. The pipe that carries water from the tank to your home is often clogged with sediment.

Because this is a complex problem that can have many causes, it is best to leave it to a professional. It may be time for a water heater replacement in Northridge, CA.

3. It is not enough or there is no hot water

This is not a dangerous problem, but it is definitely a drawback. If it is very cold or if the cold water that reaches your home drops to a very low temperature, this can decrease the rate at which the water heater produces hot water.

Your tank may not be large enough for your home. A 30 or 40-gallon tank does not actually hold and process 30 – 40 gallons; the number is usually much smaller. So if you are using your hot water you can go quickly and it takes time to recover.

Again, clogs and sediment buildup can cause this problem. Have a plumber inspect the heater. Need a new water heater? For water heater installation in Northridge, CA, give All City Plumbers a call today.
