RO filter fittings on the Island?

[jon.smolders]

Anyone know where I can get an inline valve for my RO filter?? I want to tee it off from the 3/8" line under the sink. I have the brass 3/8" t-connector and the brass 3/8" to 6.4mm (1/4"?) tubing adaptor, but I need a way to turn it on and off. I can't find it at home depot. I know they're called John Guest fittings on Reef Central... anywhere in Nanaimo (or Vancouver Island) to get them?

I also need some sort of bulkhead for the same 6.4mm tubing for a gravity fed auto top off... if they exist. How do you connect auto top off tubing to the reservior? Is there an easier way? (3/4" bulkhead to 1/4" tubing adaptor?)

Thanks
