From home plumbing to large scale irrigation, plastic pipe is installed to move water from the source throughout a home or installation. Holes caused by damage or normal use must be repaired to prevent water from being wasted and potential damage to the surrounding area. Instead of replacing the pipe, consider an patch designed for long term repair.
