HepvO can be installed vertically or horizontally, or any angle in-between. When installing horizontally a minimum allowable slope of 1/8” (3.175mm) per foot (30.48cm) must be maintained to ensure good drainage. This can be achieved by using the HepvO Angled Adapter supplied in the HepvO kit.
When installed at any angle other than vertically, the HepvO must have ‘ribs down’ to ensure correct drainage.
HepvO valves must be installed in the correct direction of flow which is clearly marked on the body of the product.
HepvO must be installed either immediately at the exit of each fixture, or in-line up to a maximum distance of 6ft from the exit of the fixture. Note that when used to protect a single fixture HepvO must always be installed upstream of any tees or branch connections to other waste pipes.
HepvO must be installed in an accessible location.
