Hi,
We are looking to revamp our upstairs bathroom and downstairs loo and wondered if any systems exist that can use the grey water from upstairs? With gravity on your side i would think something would exist that uses the upstairs grey water and stores it in a 'primary cistern' to use to flush the toilet and then in the event that runs out use a fresh water tank or just feed fresh water into grey water tank to top up/flush the toilet. I was thinking with ball valves closing one from the other etc it should be relatively easy. It means the grey water would be constantly used and not sat for weeks. Are there issues with bio 'horribleness' building up and venting etc?
Any help would be great. We've go plenty of head room and it seems a shame not to use the sink/shower water for flush the toilet.....
