Is the DF5000 safe for the plumbing pipes? They won't cause any erosion over time will they?
The DF5000 Drain Gel is not corrosive to plumbing pipes whatsoever. The drain fly treatment products are actually a bacterial formulation that are only effective on organic matter built up in a drain and will not eat through metal, polyurethane or any other type of plumbing pipe.
