Keeping up with your water heater’s maintenance can prolong its lifespan. It’s recommended to drain your tank at least once per year. Anode rods should be replaced every three years to prevent corrosion.
Leaks are also a common problem, and they should be fixed right away to avoid flooding or mold damage. If you notice strange smells or discoloration in your water, call a licensed plumber at Denver Water Heater Repair for help.
The thermostat is a critical component of your water heater that regulates its heating. It is the electrical switch that turns your heater on and off depending on a desired temperature set by you. It works by measuring the temperature and sending a signal to your heater to start or stop heating based on that measurement. Thermostats are available in various designs and configurations, including manual and automatic ones.
Typically, when there is an issue with your water heater that can’t be resolved by flushing the tank or draining it, your thermostat may need to be replaced. The best way to find out if this is the case is to perform a test on your unit’s heating element. This test will help you determine whether your thermostat is working properly or not and can also let you know if any adjustments made via the thermostat are accurately reflected in your hot water supply.
To perform the test, you will need a multimeter and a red tester lead. First, make sure your gas water heater has been shut off. It’s important to do this before beginning any maintenance on your gas water heater as natural gas can be dangerous if handled improperly. You should also take a moment to identify the location of your gas water heater’s control valve. Typically, this is located on an external pipe connected directly to your unit.
Once you’ve turned off your gas water heater, you can begin testing its components. To ensure you don’t get shocked, you’ll want to shut off the power to your heater as well. Next, remove the top layer of the thermostat and disconnect the red tester lead from its terminal. Use the meter’s “Ohms” or “Resistance” jack to check the lower terminal on the thermostat. If line voltage is present on the thermostat, it must be heating the water unless your heating element has failed. If it isn’t, you have an open circuit that will need to be fixed by replacing the upper or lower thermostat. If you’re not comfortable performing this step on your own, contact a professional. They will be able to safely troubleshoot your heater and repair it.
We all use our water heaters to keep our homes comfortable. They’re also critical for showers, laundry and cooking. So, when yours starts acting up, it can have a big impact on your daily routine. If yours is leaking, making strange noises or producing less hot water than normal, you should call a Carter professional immediately.
If you’re dealing with an electric unit, a bad heating element is the culprit. Located at the top and bottom of your tank, these elements work by passing an electrical current through them. When one of them fails, your water won’t reach the temperature set on your thermostat. To test for heating elements, first, make sure the circuit breaker is on and not tripped. Then, using a digital multimeter, measure the line voltage to see if the element is functioning. If you can’t find a good reading, or the reading is higher than 208 volts, it’s time to replace it.
The dip tube, meanwhile, transfers cool water to the bottom of your tank so it can be reheated by the lower element. When the dip tube breaks down, cool water gets mixed in with your hot, reducing overall water temperature. A new dip tube costs $15 to $20.
Gas units can experience similar issues, including the thermocouple and pilot light. If you have a gas unit, you should hire a professional to relight your pilot light and check the gas control valve for proper operation. Do not attempt to do these tests yourself without a complete safety manual for your specific unit, as there are real dangers involved.
The dip tube is one of the most important parts of your water heater. It keeps cold water from contaminating your hot water supply. It also allows for a consistent supply of hot water. If you’re experiencing a drop in the temperature of your hot water, a defective dip tube is the likely culprit.
When the dip tube is damaged, the cold water from the bottom of the tank mixes quickly with the hot water. The resulting water temperature is much lower than normal and will cause you to suffer from lukewarm showers and washing machines.
Water heaters use a long piece of white plastic tubing, called a dip tube, to keep hot and cold water separate. It’s attached to the inlet port on the top of the tank and droops down about 8 inches. As hot water is drawn from the top of the tank, it pushes the cold water down to the bottom where a burner heats it up. The resulting hot water rises to the inlet port and is drawn out for consumption.
Over time, these tubes tend to deteriorate from their constant submersion in water. The metals from hard water build up inside the plastic and break down the tube over time. Fortunately, non-metallic dip tubes are used in modern water heaters, because they can withstand high water temperatures and are less prone to corrosion.
Depending on the age of your water heater, you may need to replace your dip tube. If you’re experiencing problems with a dip tube, check the serial number on your heater to determine whether it was produced before 1993. Many manufacturers released water heaters with defective dip tubes during that period.
You’ll need a few common tools to repair your water heater’s dip tube, including a flat screwdriver. First, shut off the power and the water to your water heater by turning off the circuit breaker or gas dial. Then, drain the tank and disconnect the cold water inlet pipe from the tank. Pull out the old dip tube and install a new, durable tube made of cross-link polyethylene (PEX). Make sure the tube reaches all the way to the bottom of the tank.
As the water inside a hot-water tank heats, it expands, which causes internal pressure to build up. It is normal for some of this pressure to escape through the water pipes that connect to the heater, but if this does not happen, excess pressure can accumulate until the tank bursts, flooding your home. That is why the hot-water heater has a safety mechanism called the pressure relief valve.
When the pressure in a water heater exceeds a preset level, the pressure-relief valve opens to release a small amount of hot water and steam. This reduces system pressure to a safer level, protecting the heater from damage.
The pressure-relief valve is a simple device that consists of an elongated metal disc with a small hole in the center. As water enters the valve, it pushes against the disc, lifting it and allowing some fluid to bypass to the reservoir. The amount of fluid that is released is controlled by an adjusting screw that compresses or decompresses the spring.
While it is possible for a homeowner to repair a gas water heater pressure-relief valve, the process requires extensive knowledge of plumbing and electrical work. This is why it is best to call in a professional to perform this service.
Before beginning any repairs, it is important to shut off the gas supply and take precautions against fire or explosion. It is also a good idea to wear gloves and protective eyewear when working with high-temperature components in a hot water heater. Ventilation is essential.
It is also essential to ensure that the direction of flow through your PRV is correct. This can be determined by checking the arrow on the valve and following the installation instructions. If your valve is installed backwards, it will not function properly.
Once the tank is empty, the final step is to conduct a hot-water test to confirm that all the repairs have been successful. Turn on a faucet to see if you can get hot water from it, and then check the temperature of the water by running your hot-water tests again.
