Pipe Straps securely fasten your PVC pipe in place, preventing pipe movement and possible deterioration and breaks at glue joints.  Due to the nature of retractable hose systems, where the hose is being pulled into and out of the pipe network, pipes have a tendency to shift a bit.  Over time this may lead to joints coming loose and failing. It is important to strap the pipe system in place to avoid this possibility.  1 to  2 straps per pipe per 8 foot section is sufficient.
