plumbing
I can't figure out how to hook up the incoming water to my reverse osmosis system. I want to tap off the braided hose here, and use a quick fit for the plastic tubing but have searched and ordered two parts and can't seem to figure out what is correct.
You're going to need to get a 3/8" x 3/8" x 1/4" brass tee, like this one from Home Depot.
Then you'll simply screw the tee onto the male end of the shutoff valve (where the cold water supply line should currently be attached). Attach the supply line (that you removed from the shutoff valve) to the male end of the tee. Finish the installation by attaching the tubing to the 1/4" outlet using a compression fitting (Which should be included with either the filter or the tee).
What you call a pressure tank is actually a storage tank. RO filters always produce a very low flow which gets stored in the storage tank to supply the user.
You probably need to depressurize your storage tank below your water supply pressure so that the storage tank will accept the water from the filter.
