Check the outside of your pool for any rusting fittings that might be connected to the filter or heating system. Remove and replace these fittings with new copper piping or plastic.
Drain your pool water. To get rid of the rust color, you must remove all the water. Start by releasing the drain valve.
Suck up the remaining orange water using a pool pump.
Scrub any areas of your liner that have been contaminated with the orange water. Use a nylon scrubber and tile-and-liner cleaning product.
Rinse the areas you scrub with a bucket of water. Pump out the water with the pool pump.
Close the drain valve and refill your swimming pool. The orange-colored water should now be gone.
