Wavin Osma HepVO waste valveHepᵥO overcomes problems sometimes associated with conventional water traps. HepᵥO will not lose its seal due to evaporation, movement, vibration or siphonage. HepᵥO is not prone to cracking in freezing conditions and prevents “gurgling” noises in waste pipe, which can sometimes happen when water traps are subject to negative pressure.
