So I bought a used watts premier 'pur-tek' RO filter on craigslist today ($30!). I plan on getting new cartridges for it. However I'm a bit worried about the T fitting on top of the accompanying pressure tank, as it is brass. Does anyone know of a plastic replacement for this particular part?
Follow up question: it occurs to me that maybe I shouldn't even be using the tank. I'm not 100% on this, which is why I'm asking, but I believe that the tank is a pressure tank so that when it is filled the back pressure will cause the shutoff valve to...shutoff, and then the pressure tank is enough to push the water up to your faucet. Since I'm pretty much just using it to fill the tank, maybe it would be better to have the output of the filter just go straight into the display tank, instead of through the pressure tank (and the brass fitting)?
Please advise,
Robin
