You will need:
- Small-scale graywater system kit
- Filtration unit
- Waste pipe and connections
- Compatible water butt
- Fine-toothed saw
- Silicone sealant
- Solvent cement
- Jubilee clip
1. Mark on waste pipe where the combination outlet will be installed. The markings should be a little shorter than the actual outlet to allow for the cut ends of the waste pipe to be fit into the sockets of the combination outlet.
2. Use a fine-toothed saw to cut the marked section of waste pipe.
3. Hold up the combination outlet in the space you've just created by cutting the pipe. Mark an outline on the wall around the section of combination outlet that touches it. This will be where you will route the drainage pipe outside.
4. Use a core drill bit to in the marked position you've just made on the wall.
5. Cut and fit a piece of waste pipe long enough to attach to the section of combination outlet and go through the wall.
6. Adjust the length of the waste pipe that is protruding through the wall from the combination outlet to the exterior wall. It should be long enough on the exterior side to fit a piece of elbow pipe.
7. Align the elbow on this section of waste pipe and seal with silicone sealant.
8. Fit pieces of of waste pipe from the bottom of the elbow pipe down to a point just above and adjacent to the water butt. Screw in brackets.
9. Assemble the filter unit.
10. Refer to the guidelines about filter alignment and place filter unit on the water butt.
11. Attach the hose tail adaptor to the bottom of the water pipe.
12. Join the pipe and the filter using the hose.
13. Secure all waste-joint pipes in place with solvent cement.
14. Use a jubilee clip to secure the hose.
