Thanx for the Input. Glad somebody finally understands what I was getting at......
The RO unit just arrived about an hr ago, so I've been putting it together, but not actually installing it yet!
I am already Tee-d into the cold water supply for a variation of Wasserpest's auto-WC system. It cost me about $12 to get the fitting to go from the standard house plumbing Compression fitting to NPT. All I need for cold water is another NPT Tee. But for the Hot water its another $12 for the fitting!
Then Tee both of those lines together with a small ball-valve on the hot side and it should be good to go.
I bought the Booster pump, so this system should be kicking at about 80psi. And it came with the Milwaukee TDS Meter (CD97) and PSI Gauge, so I'm pretty much good to go.
I won't be hooking up the Hot water supply any time soon--too many other things to sort out. But I may give it a whirl in the near future.
Thanx for following this through with me!
EDIT: I did TDS tests on my water supply: Cold 307ppm, Hot 258ppm!, Distilled 10ppm. The Hot actually reads Less!
EDIT2: Well, its not formally installed, but it is up and running. Luckily, I've been into enough stuff over the yrs that I had on hand the fittings and Icemaker tubing to connect up to the kitchen sink via the python faucet attachment. So, I am currently mixing Hot and Cold as is the topic of this thread. We'll see how it goes.......
