Prevents the escape of foul sewer air from
waste discharge systems.
Actively maintaining a pressure equilibrium in soil and waste
installations.
HepVO is a hygienic self-sealing valve
designed to close the waste connection below a sanitary
appliance to prevent the escape of foul sewer air into the
dwelling.
HepVO actively eliminates negative pressure
within the waste system by opening and allowing in fresh
air until a state of equilibrium with atmosphere is reached.
This means that venting of the waste system, or the inclusion
of air admittance valves in the waste system is no longer
necessary.
The HepVO valve means enhanced plumbing
design and system efficiency, without compromising performance
or risking the escape of foul air into the living space
from the drain or sewer. The HepVO valve can be installed
vertically or horizontally (with an adaptor) and is available
in 32mm and 40mm.
