Flow-Liner® Systems is the national distributor for Pipes Down Under®. PDU is an innovative company providing a
patented Trenchless Pool Pipe Repair system for the repair of leaking or cracked underground swimming pool piping without
the need to excavate. This patented process will perform Underground Pipe Repair in a fraction of the time it takes to excavate
and replace the existing pipe and will save thousands of dollars in machinery costs, time and labor costs along with non
disruption to the swimming pool environmental surroundings.
PDU liners are carefully made of materials such as Santoprene TPR (NSF-61) and EPDM (FDA 21 CFR 177.2600). The annealed external polypropylene
helix prevents liner collapse, increases integrity and minimizes resistance during pipe insertion. Liners come in
basic 25, 50 and 100 foot-lengths ranging in size from 1 ½" to 2" in diameter. Lengths and diameters can be increased for
certain applications.
Residential, commercial and municipal swimming pools
Decorative fountains and waterfalls
Note: For larger diameter piping Flow-Liner offers cured in place pipe liners.
