1. Locate and open manhole cover and identify direction of flow from the property by running taps and flushing toilets, non return valves should be fitted to every outlet from the property to ensure complete protection. Ensure outlets are suitable for the installation of the valves, if outlets are curved then modification may be required to allow room to install.
2. Apply latex Gloves and eye protection to protect against splash back of sewage
3. Clean all outlets and ensure they are free from dirt or debris.
4. Push Valve into outlet a rubber mallet maybe required to gently tap the metal body of the valve pushing it into the outlet, valve should be pushed in enough so that the rubber seal is just visible.
5. Ensure flap operation is correct by running the water through the pipe by flushing the toilet or running taps.
6. Ensure hinge is aligned vertically and flap opens and closes without fouling.
7. If using the retaining cable drill hole approximately 5-10 inches above the valve into the wall of the chamber and push in the raw plug, screw in o ring screw and attach the cable (The cable prevents the valve from blocking the sewer if in the unlikely event it became loose)
8. Maintenance by inspection of the valve should be carried out once per year ensuring hinge is functioning correctly.
