Poly. Poly pipe is a soft plastic pipe that comes in coils and is used for cold water. It can crack with age or wear through from rocks. Other weak points can be the stainless steel clamps or galvanized couplings.

Much has been written in the past about Hydrogen Sulfide corrosion in wastewater pipelines. The EPA published a number of papers, pamphlets, and reports to Congress on this subject. More and more papers and studies today, attribute Hydrogen Sulfide corrosion to air pockets, including a number of papers presented at the ASCE Pipelines 2009 Conference in San Diego. Most of these papers refer to detection, monitoring, evaluation, assessment and management of corrosion, but not of prevention. They point out the contribution of air pockets to Hydrogen Sulfide corrosion, but they do not discuss the means and ways of preventing air pocket accumulation.
When pressure in locations along the pipeline falls below atmospheric pressure (at water column separation due to pump stoppage, for instance), air can be sucked into the pipeline at above-surface pipe sections, through faulty joints, past poorly positioned seals and gaskets, through pipe accessories, through air valves, through cracks, or through other gaps in the pipeline. 2ff7e9595c
