I'm installing iSpring RCC7AK filtration system in a rental apartment so I'd love to minimize impact on existing equipment.
I'm considering 4 locations to connect:
- Drill a hole in the cap. I can't use saddle so I guess I'd have to glue the pipe;
- Drill a hole on top of the wide tube;
- Drill a hole on the side. Too big to use included saddle;
- It's drain tube from washing machine.
Currently I'm tempted to go with option (1) because I can easily replace the cap. I like location (4) as well but I wonder if there is a risk contamination of clean water in RO tank when washing machine is draining water.
Where should I connect it? Is there better option that I haven't mention?
