Grant, If you run 3/8 to the shower you should be able to pull the controls out if the tubing is long enough. If 1/2 or bigger better have access to the back.  Tom Y

Hi Grant,
Have you ever taken a faucet apart? If you have, you know that the ports are no larger than 1/4". Use the 3/8" lines, you will have all the water you need. And, at a very reasonable price.

How often do any of you use more than one faucet at a time? We almost never do.

Good luck, Sam 4106

I have the opportunity to purchase 500 ft of pex 1/2 od, 3/8 id (250ft in red and 250ft in blue) for $50. I was hoping that once I am done someone else on the board can use what I have left?

Thanks for all the help.

Grant, one way to figure it is the new faucets and shower heads  use very little water the bathroom use more water than any place a new shower head will use 1.5 gpm the new faucets use 3.5  pm you can add aerators to them and bring that down to a 1/2 gpm so with a kitchen and bathroom faucet with aerators that is 1 gpm add the 1.5 gpm for the shower and you are talking about 2.5 gpm and with the right pump you could even flush the toilet while using everthing. My water system was a over kill and I am planing to change over to all the low water use items that way gray water will not be a problem anymore for me use the $50 stuff sounds good to me.I have the criping tool and cutters you can use if you will return  them to me

Grant,
    A couple tips. First, buy a pair of the pex/CPVC cutters.  The are kinda like a ratcheting piers looking thing and available at any home supply store. It is much easier to get a good clean square cut using them.
    The Sharkbite type fittings (available at Lowes and online) are easy to use AND if you change you mind and find a better path to run the tubing, it is easy to disconnect, re-route the tubing, and reconnect.  Jack

 If you have the crimping tool the crimp style is by far the cheaper compare 10 bucks for Sharkbite to 2 for the brass and a buck for polymer for the fitting buy you plently of drain valves the are not that expenseve for Pex

Sharkbite fittings are at Home Depot too.  I haven't seen them at Lowes but I haven't looked in a year either.

I went with the crimp system initially and some of the crimps leaked for various reasons.  Sharkbite fittings for my whole bus are going to cost $200 at the most.

Last I looked, the crimpers were over $100.00. The thing I don't like about the crimped fittings is that once crimped, that's it, no changing the route the tubing takes.  Just my way, YMMV  Jack

I like the board because after I learn it, I don't have to remember it,  I do a search then ask again after i don't find it Cheesy

I used the plastic push fittings at lowes and HD. work on pex, copper & cpvc,   Since my bus i already some what converted and it is easy to remove which i have had to do,  also some spots would not allow crimpers.

also if you forget to put a drain or have a fitting in a low spot, you can still drain it.
