Good morning all. I am plumbing a new bath in my basement and have some questions regarding size of distribution/supply pipes. The following is existing: (1)DWV system is in place (2)water supply is a private well (3)Water enters house via a 1" rubber hose and connects to a 1"brass pipe and anti back-flow device (4)this 1" line goes to Amtrol pressure tank and exits tank via a 3/4" copper distribution run with a whole house filter close to the beginning of this run (5)the 3/4" pipe runs approx. 12' towards the center of the house and then starts to branch off to kitchen, 1 bath, laundry, boiler, hose bib, AND doubles back to water heater all with 1/2" copper and exits the water heater also with 1/2" copper and supplies hot water (obviously) to fixtures requiring it (6)house is small - 24x30' (7) new bath is 29' from water supply entry point into house and also 29' from water heater. OK. Now my questions. (A) Shouldn't the line to and from the water heater be a 3/4" distribution size (as is the cold)? If so, should I upgrade it to 3/4 or leave it as is? (B)Should the distribution pipe from the existing 3/4" cold run to the new bath also with 3/4" and then go to 1/2" branch lines or should I use 1/2" branch lines all the way from existing to new bath? Whatever is done with the new cold (3/4" or 1/2") will be done with the new hot run. (C) I assume that running branch lines down from ceiling to new fixtures (via 1/2") is OK and won't adversely affect water pressure to a significant degree (D)I plan to run new supply line first to shower then branch of it to sink and toilet. Is this OK? (E)Finally, when complete, farthest run from entry point/water heater will be 30' as the crow flys and a total of approximately 70' total pipe run each hot/cold (not including hose bib or boiler) and will service 2 vanity sinks, 1 kitchen sink, 1 tub/shower, 1 shower only, 2 toilets, 1 washer, 1 hose bib, 1 boiler. Will this work? Appreciate any advice you can give me. Hope I've given enough info (probably too much)

Thank-you for the info! Spent an hour and half at a plumbing supply showroom yesterday! Won't know until room is gutted what the current drain lines look like and if it will be easy (and not expensive) to move the toilet. Everything hinges on the toilet! haha. Picked out items that I liked but didn't order anything yet. Like the Kohler Artifacts line and the faucet is similar to your Moen's @crl. Will probably go with that line's shower head and hand held, Memoirs Stately toilet. Think it all keeps within the traditional style of the room and house and still clean lined. (liked the Grohe lines, too, but thought the Kohler Artifacts line was a better match for the room). Even picked out a drain cover--who knew there were so many choices! And no tub. In fact taking out the tub. Rarely used, gives us much more room to play with and we have two other tubs in the house.

" My problem is how to search for valve trims that will allow me to control all three of those things separately." Easiest way is to find the rough in valve body that can accommodate your diverting needs. THEN look at the trim kits for that valve. You can mix and match manufacturers if you stay within a common finish like chrome. A valve and valve trim from one manufacturer. Shower head from another. Shower arm from a third. Slide bar and handheld assembly from a fourth, etc.

You can read our in-depth reviews of the sink faucets offered by these companies including the identity of the actual manufacturers of the faucets, quality,. warranty, customer support, certifications, complaints and issues; and a list of companies selling similar faucets starting at the Index to Faucet reviews at http://starcraftcustombuilders.com/sources.faucets2.htm.  We do not review showers , tub fillers, or bidet faucets, but I have little doubt the quality is the same overall.
