If you've ever had to stick your hand down the toilet pan to get your keys out, or even if you have a pet that likes to drink from the water, you might be wondering how dirty is toilet water? The good news is, it's pretty clean compared to other household water sources.

The tank is a lid, so you can't see inside it. That's why it's important to check it out every so often.

Inspecting the toilet tank can reveal a variety of problems, including mold and algae, rusty pipes and mineral deposits from your water supply. You can also notice a greenish tint to the tank water, which could indicate the presence of iron.

Getting rid of these issues isn't too difficult. First, empty the tank and use a disinfecting cleaner to wipe down the sides and all internal components.

Next, rinse the tank and refill it with new water. If you see a brownish hue, it could be due to a buildup of hard water minerals.

You'll need to flush the toilet several times to remove the minerals and soil from the tank. It's best to use a water softener or other treatment for your water to prevent the problem from recurring.

If the problem still persists, contact a plumber for help. They may be able to treat the plumbing or replace the pipes. They might also be able to provide tips for getting rid of the discoloration in your tank water.
