If in doubt lay out the footage you need hook it up and measure the flow.five gallon bucket and a watch will answer your question. Should have plenty of flow for that situation.

The wife's whirlpool tub takes awhile to fill. I have 1/2 inch pex for all my lines in the house. Posted 18:30 (#2730990 - in reply to #2730743) Subject: Re: Water flow rate in pex tubing I would think that 1/2 pex at 40psi would put that out and then some but would like to verify that. It looks like most showers need about 2 gpm. I think 3/4" would be a safer bet for the interior line but I have the crimper and some connections for 1/2. The origination point is 1" plastic underground. There will be minimal connectors between the supply origination and the restroom. Only one of these fixtures will run at a time. There will be a toilet, sink and a shower. I need to run a supply line on an interior shop wall to supply the shop restroom.

You're spraying with an open ended piece of PEX tubing? If you're pumping in a closed loop you like don't have 40 psi differential over the 60 ft, probably only a psi or so. Posted 12:42 (#2730562 - in reply to #2730476) Subject: RE: Water flow rate in pex tubing I wasn't sure it really answered my question but again, I may be missing the bigger picture. Seems like a wide variance to me and there is no reference to the length of run used. The middle (yellow ) column of the first chart looks like it's based on 20 to 100 psi.

Anyone have an idea? I must be making more work out of this than necessary, lol. I must be missing something, I have searched under numerous parameters and turn up nothing useful.
