Sil-O-Flex® Water Well Systems

IPEX Water Well Piping systems are manufactured using HDPE resin to ensure a durable, cost effective and low maintenance solution for water well applications.

Sil-O-Flex® Water Well products are typically used in water service line applications from the meter or well to the house, from the house to an exterior faucet, irrigation, or to hang a submersible pump or foot valve in a well. Products are resistant to corrosion and chemical attack by acids, alkalis, salt solutions as well as many other chemicals.
