Orange stains and metallic taste: iron in water

Signs of iron in your well water

Iron is a common mineral found in groundwater across many regions. When well water contains dissolved or particulate iron, you will notice clear signs around your house.

The most obvious sign is orange, red, or brown discoloration on plumbing fixtures. Sinks, bathtubs, and toilet bowls slowly pick up rusty rings that do not wash away easily with regular soap. White laundry may come out of the wash with a dull yellow or orange tint.

You might also notice a metallic taste or smell when drinking water straight from the tap. Sometimes the water looks completely clear when you fill a glass, but turns reddish after sitting out in the air.

• Orange or reddish-brown marks on porcelain and tile
• Yellow or dingy white clothing after washing
• A metallic taste or odor in drinking water
• Visible rust flakes or sediment settling in toilet tanks

Test your water first

Before choosing any filtration setup, you should test your well water. A simple test tells you how much iron is present and what form it takes.

Iron can exist as clear water iron or red water iron. Clear water iron is dissolved, so the water looks clear until it meets air. Red water iron is already oxidized into solid particles that float in the water.

Testing also checks for other minerals like manganese, which often appears alongside iron and leaves dark brown or black stains. Knowing your exact water chemistry helps you choose the correct filtration approach.

Whole house systems for iron

A whole house filter treats water at the point where it enters your home. This protects every pipe, faucet, and appliance from sediment and mineral buildup.

Whole house sediment filters catch visible rust particles and grit before they reach your indoor plumbing. For example, the Waterdrop BG100 Reusable 5 Micron Whole House Sediment Filter traps solid particles at the main line.

Multi-stage systems offer extra filtration stages in a single setup. The Waterdrop WHF21-PG 2-Stage Whole House System, 5 Micron provides two stages of filtration and is NSF/ANSI 372 Certified as stated by Waterdrop page text. Using a whole house system ensures treated water flows to your kitchen, bathrooms, and laundry room.

How to match the right system to your home

When selecting a system, check the micron rating and the filter type. A 5 micron filter captures fine particles that cause cloudy water and visible staining.

You can match replacement filters by looking at the model number of your current system. Labels are often placed on the side or front of the filter housing. Searching by that exact model number helps ensure you find the right fit.

Changing cartridges and basic maintenance

Every filter is built to handle a set amount of water, which is its rated capacity. Over time, trapped particles fill the filter media and slow down your water flow.

As rough guidance, whole house sediment filters are changed about every 3 to 6 months. However, the interval listed on the product page and in your user manual always wins. If you notice lower water pressure at your faucets, check the filter sooner.

Always run some water through a new filter before you drink it. Follow the flush steps listed on the product box or manual to clear out loose media.

1. Turn off the main water supply to your house.
2. Open a nearby faucet to relieve the remaining water line pressure.
3. Open the filter housing and take out the old cartridge.
4. Clean out any loose sediment from inside the housing bowl.
5. Insert the new cartridge and seal the housing securely.
6. Turn the main water supply back on slowly and check for leaks.
7. Flush water through the line as directed by the manual.
