Sprayed-in-place pipelining works exactly the way it sounds. A spray head is inserted into your plumbing pipes and threaded down the line via a special hose. As the hose is retracted, the spray head sprays a thin layer of epoxy or polyurea, which completely coats the interior pipe walls. Our color-coordinated heavy-duty spray hoses are constructed out of sturdy PVC with five-ply bonded construction. That makes it durable in particularly harsh environments. From a composition perspective, our chemical spray hose is resistant to fungicide, insecticides, fertilizers and much more. A hose-end sprayer is a container/sprayer nozzle combination tool that allows liquid products to be mixed with water right at the end of a hose. This tool provides a fast and easy way for homeowners to apply liquid gardening products.
