How do you end up with a dirty water heater tank?
You may be dealing with a dirty water heater tank for one of two reasons. First, minerals or sediment buildup in your tank can leave behind grime or dirt. Second, your tank can corrode, leaving you with a rusty water heater. It may be unpleasant, but both of these causes are normal.
How to check for a dirty water heater tank
Run the hot water out of one of the faucets in your home, and inspect its appearance. Is it discolored, dirty, or rusty? This could be an issue with your hot water heater tank.
Try running the cold water out of the same faucet tap and inspect its appearance. Does the cold water also appear dirty, discolored, or rusty? If it does, then this issue is likely unrelated to your hot water heater and may instead be an issue with another part of your plumbing system, such as your supply lines or pipes.
Once you've confirmed that it's only the hot water that appears dirty, run the faucet again and inspect it more closely. Would you describe its appearance as more dirty/discolored or rusty?
If you would describe it as rusty, you've likely got a corroded water tank on your hands. If you would describe it as dirty or discolored, you likely have mineral, sediment, or dirt buildup in your hot water heater tank. You'll need to flush out the tank to drain the sedmiment.
If this didn't get to the bottom of the issue, check out other causes of hot water heater leaks.
What To Do If You Have a Dirty Water Heater Tank?
The process required to fix a dirty water heater tank depends on the type of "dirty" you are dealing with. If your tank has sediment or mineral buildup, all it needs is a good water heater tank flushing!
