  1. 1

    Turn off your water while working on your pipes.

  2. 2

    Purchase a chemical product such as Lime-A-Way or CLR. Mix in a 50/50 solution with water, and flush it through your pipes. You may also have success with a product such as Drano Foaming Pipe Snake.

  3. 3

    Go green. If you are looking for a "green" solution to this problem, flush the water pipes with white vinegar. The vinegar will dissolve the calcium build up.

  4. 4

    Use a filtration system. The most expensive option is to install a water filtration system that uses reverse osmosis or a similar method.

  5. 5

    Clean your shower heads and faucets to remove calcium deposits. Detach the fixtures, and allow them to soak for several hours in Lime-A-Way or white vinegar.

Tips and warnings

  • A more expensive option is to install a water softener system in your home. This will be a much more effective solution to your problem.
  • Be careful when using any sort of harsh chemical to clean your water pipes. If the water flows to a reservoir for drinking water, you may contaminate the portable water supply.
