Things You'll Need

  • Calcium and lime reducing product

  • Septic tank cleaner

If you have found that your water pressure and drainage are not what they used to be, deposits within your pipes are a likely culprit. There are two main contaminants that build up on the insides of pipes and restrict water flow: mineral deposits, such as calcium and lime, and organic deposits, such as hair and soap scum. Both of these are easy to remove. Clean your plumbing pipes regularly to keep them working at peak efficiency.


Step 1

Turn off the main water supply to the house.

Step 2

Remove the faucets from your sinks, showers and bathtubs. These faucets typically either twist off or are held in place with a screw.

Step 3

Mix a solution of half hot water and half calcium and lime remover.


Step 4

Pour the mixture down the pipes and drains and allow it to sit for one hour.

Step 5

Replace the faucets and turn the water supply back on. Turn on all faucets to flush the pipes clean.

Step 6

Mix 1 tbsp. of powdered septic tank cleaner with 16 oz. of warm water.


Step 7

Pour one batch of this mixture down each drain in your kitchen and bathrooms. It does not need to sit for any particular amount of time; it will adhere to organic residue even if water is flushed down the pipes immediately.


Wear protective gloves when using these products.
