Everflow pipe couplings and adapters are used for all types of in-house and sewer connections: drain, waste, vent piping, house-to-main, repairs, cut-ins, conductor, roof drains and increasers-reducers. Manufacturing thousands of different flexible coupling types, Everflow has the right solution for most applications. Made of tough elastomeric polyvinyl chloride (PVC), the flexible couplings are strong, resilient and unaffected by soil conditions. They are also resistant to chemicals, ultraviolet rays, fungus growth, and normal sewer gases due to the inert nature and physical properties of the PVC material. Everflow flexible couplings are leak-proof, rot-proof and seal against infiltration and exfiltration, giving you confidence in your pipe connections. ***CALIFORNIA PROPOSITION 65 WARNING: This product can expose you to chemicals including Phthalates content which are known to the State of California to cause cancer, and birth defects or other reproductive harm.
