Cu-Foam packets are USED WITH copper sulfate pentahydrate to contact the roots above the water line using a PROPRIETARY BLEND of ingredients that WILL FILL THE SEWER LINE WITH FOAM.
*Cu-Foam does not contain a root killer and will not control roots. You must use our EPA labeled COPPER SULFATE PENTAHYDRATE for ROOT CONTROL.
Cu-Foam packets are USED WITH copper sulfate pentahydrate to contact the roots above the water line. We use a PROPRIETARY BLEND of ingredients that WILL FILL THE SEWER LINE WITH FOAM AND COPPER SULFATE WHICH ERRADICATES THE INTRUDING ROOTS.
*Cu-Foam does not contain a root killer and will not control roots. You must use our EPA labeled COPPER SULFATE PENTAHYDRATE for ROOT CONTROL. Cu-Foams foaming reaction with copper sulfate only helps the copper sulfate reach the entire diameter of your sewer line.
One packet of Cu-Foam is placed into the toilet or clean out along with the recommended amount of copper sulfate (about 2 pounds per treatment-- refer to copper sulfate label.) Once the Cu-Foam water dissolvable packet starts to disintegrate ( in about 30 seconds) the toilet should be flushed. The EPA registered root killer (copper sulfate pentahydrate) and Cu-Foam WILL THEN DISPERSE THROUGHOUT YOUR ROOT INFESTED SEWER LINE causing them to die within a few days. As the foam generates and coats the entire diameter of the pipe, THE COPPER SULFATE IS TAKING A RIDE ON THE FOAM REACHING ALL OF THE ROOTS--- THIS ACTION IS NOT PRESENT IN OTHER PRODUCTS!
Let the treatment sit as long as possible in the treated line-- this is done by not using the other drains and toilets throughout the house after you have flushed the treatment. In most cases, all the drains lead into the main line that has the root issue, so running water down a drain (ie. washer machines, showers, sinks and toilets) can push the treatment out of your infested sewer line before coating the roots with copper sulfate is complete.
Treat at night right before bed, or during the day if the house will be vacant for a few hours (approx. 3 hours).
Drought conditions-- like little or no rainfall and excess summer heat will increase the trees need for water. Tree roots will set out to find the nearest water source, which usually ends up being the sewer lines. Pay attention to your system during these conditions, listening for gurgling toilets and drains and looking for slow drainage. These are signs that roots are blocking your sewers flow.
