Hello. I recently purchased a home serviced by a well. This isn't really a well-related question per se, as I'm mostly concerned with the house-side of the pressure tank. So, here goes: There's the usual well arrangement; submersed pump, 3/4 or 1" PVC tubing to pressure tank assembly, which consists of pump controller, relief valve, drain valve, the tank, and then a service shutoff valve leading to the home plumbing. All this piping consists of threaded galvanized pipe. After the service shutoff valve, there's an adapter that goes from threaded 3/4" to soldered copper 1/2" piping. Finally, the 1/2" copper leads to a bunch of bent tubing and T-adapters branching off to the hot water tank, laundry, two bathrooms, and the kitchen in a somewhat ad-hoc serial fashion. What I want to do: I'd like to upgrade the utility/service entrace from 1/2" copper to 3/4" copper, running it through some treatment equipment (5 or 20 micron filter, activated charcoal, and possibly also UV) and then onto the home. Instead of 1/2" pipe with branches, I'm thinking of moving to 3/4" x 3/4" x 1/2" T adapters in series such that each service branch 1/2" line is fed directly from a 3/4" line or "manifold". The hot water heater would be fed directly with 3/4" line and then have a similar 'manifold' scheme to distribute it to service branches. Does this all sound sensible?

I recently installed an outdoor shower on my deck. I purchased it from Orvis. It has a supply for only cold water via a hose connection and an on/off valve. I wanted hot & cold water supply so I plumbed hot & cold water from my basement to the shower. I used a standard hose "Y" connection at the shower (it has a lever on each arm for mixing and/or shut off). I now find that when the shower is off, the hot water migrates thru the "Y" back to my basement supply from the hot water line into the cold water line if the arm levers are not closed. Should I put a one way valve in the cold water line? Any other suggestions are appreciated! Thanks.
