Effectively Clear Out Tough Clogs in Pipes with Copper Sulfate Crystals

pipe roots cross section

Having tough clogs in your pipes can be a big problem, and if not treated, it can cause a pipe to burst. Copper sulfate can be your most effective and easiest solution to help clear out your pipes. Just pour less than half a cup of copper sulfate into your toilet, flush, keep the area well ventilated and your pipe should slowly start to open up. Be patient though as copper sulfate can take several days or even weeks to fully clear out the clog. Roots more specifically can get into a pipe by squeezing into small openings where there's a bracket holding the two pipes together causing tough clogs. It is important to treat the pipes when reduced flow is first noticed. Do not wait for the pipe to be completely clogged, some flow is necessary to move the copper sulfate through the clog. Order our 99% pure copper sulfate today, and never have septic problems again.

Copper Sulfate can also help increase copper content in soil and act like a fertilizer. This can help to rectify peaty and acidic soils in order to create a friendly environment for plant growth. Copper sulfate is usually used in copper-deficient soil and helps to enrich the soil by providing an essential nutrient to growing plants, thus creating a friendly environment for plants.

Clarify Ponds, Pools & Lakes

Dirt and sludge can be problematic for ponds, lakes and pools by defeating the water quality in these areas. In order to address this problem, some people turn to copper sulfate. Simply dilute 5lbs of copper sulfate with 3 gallons of hot water and spray the surface. Be cautious using it because it can take out the oxygen in the water and suffocate your fish, so you’ll want to only spray half of the area, wait 5 days and spray the other half.

metal etching

Use it For Etching

Etching is also popular with copper sulfate. A saline sulfate etch mixture can be formed using a combination of Copper Sulfate, sodium chloride, and water, leading to beautiful marks left on metal without a significant investment of time or money


Create a bordeaux mixture: Mix 3 tbsp of copper sulfate, 3 tbsp of hydrated lime and 1 gallon of water and pour it on tree trunks.

Create a spray for dirty ponds, pools or lakes: Remove all fish from pond for safety reasons first. Then mix 5lbs of copper sulfate with 3 gallons of hot water. Make sure it is completely dissolved in the water and spray only 1/2 of your pond with a pump sprayer. Wait about 5 days, and do the same treatment to the other 1/2.

Treat serious clogs in sewer lines: pour a small amount (approximately 1/2 to 1 cup) into the toilet and flush it. Repeat monthly for preventive maintenance.
