How it works

How it works

HepᵥO is different to traditional water traps as it uses a soft silicone rubber membrane to create a seal, instead of “trapped” water. HepᵥO can be installed vertically or horizontally.

HepᵥO is available in 1 ¼” and 1 ½” dimensions. HepᵥO joints are compression type. Running adaptors and knuckle bends are available as part of the system.
