Flow-Liner® products must be installed by a trained and certified Flow-Liner® Installer. Flow-Liner® products help maintain and extend the life of existing pipes, conduits and underground ducts. Flow-Liner® products must only be used in an existing approved and certified pipe, conduit or underground duct which meets the standards or specifications in which it is intended to be used for. Failure to do this may jeopardize the pipe, conduit or underground duct’s performance and safety.
