I have a under sink water filter plumbed in for drinking water, so am thinking about adding a tee and on/off valve and run a long flexible pipe to my tank. Then I can wind the pipe up when done. Will save on dechlor and carrying buckets of water.
Careful with that plan Mr Spoon. Water filters are renowned for taking out more than just what you would like, and you could very well find yourself having to add back in various elements etc that your water filter has removed.
