Hot water heaters tend to fail when they are needed the most. That being said, if you make sure that your water heater is tested and maintained particularly before the winter sets in you can prevent many of these problems. Many of the most common issues with hot water heaters include: little to no hot water Rust in the water The scent of rotten eggs A rumbling or a cracking noise A leak around the base of your heater A moaning sound Preparing for the job Before making any DIY fixes or troubleshooting your hot water heater do the following: shut off the gas or electricity to the heater.
Switch the valve off.
Drain all of the water by unwrapping the valve under your water heater.Browse 6 Amazing Benefits of Using Hot Water in Your Daily Activities – Reality Paper
Issue No. 1: No hot water Possible reasons for no hot water include: a bad gas pilot A faulty gas control valve A ruined thermocouple Possible solutions to this problem: see if the flames of the gas pilot are burning. If it doesn’t burn then that means the gas doesn’t flow as it should.
Reposition your thermocouple, secure it or remove it.
Remove the displacement valve.
Problem No. 2: insufficient hot water The key causes of this issue include: the unit is small and thus unable to satisfy enough demand A damaged or broken dip tube that enables hot and cold water to be combined A poor design that has crossed both hot and cold pipes Potential ways to fix this issue: make sure that your water heater is not overtaxed. If the demand needs 30 gallons, you will have a 40 gallon water heater, as 75 percent of its power will be hot water.
Open the nipple inlet plug, and drop the dip tube. If it does look bad then fix it.
Check to see if the connection has been crossed by turning off all the water supply. If you can see water running, open the hot water tap then you have a cross-connection. The hot water line linked to the cold water line, such as a dishwasher, shower valves or a faucet, is the most common issue.
Verify that the burner burns properly. If you have a gas heater the flame will be bright blue with a faint yellow tinge on the end.
Problem No. 3: Rust colored water Some of the root causes of this problem are: Corrosion within the lined glass tank The sacrificial anode can fail. The anode fails because the rod gradually dissolves which prevents rusting of the tank. Then it takes over until it fails absolutely rust.
Possible Fix The anode rode is simply replaced with a new magnesium pin. Those can be bought from a hardware store for plumbing.
Problem No. 4: The odor of rotten eggs Bacteria in your hot water tank feeds off the sediments to produce hydrogen gas to combines with your sacrificial anode’s decline.
Possible ways to solve the problem: flush the water heater entirely, then apply 2 pints or about 3 percent of a concentrated peroxide solution to around 40 gallons of water. Throw some of this remedy into your watercourses as well.
The solution will remain approximately 2 hours in your tank and pipes. The solution is not harmful and so you don’t need to clean it.
