That's why you gotta keep your tongue IN YOUR CHEEK or risk shorting out the keyboard. And my keyboard is centered between a couple QR concealed sprinklers.....just in case.
Hey- let's go back to getting the NAHB in check. Strangely enough, I think we just joined an affiliate of NAHB (to save $23,000/yr on our health insurance) so I'll check with my boss and see if it included website access of NAHB's site. If so, I'll download and help them spread their message- to their foes. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, April 25, 2007 4:54 PM To: [email protected] Subject: RE: 1/2" thread - 8 K sprinklers I usually use my fingers for typing, George's way seems like it would make the keyboard all wet..........

The problem would be that it isn't an existing system until AFTER it is accepted. This requirement has been in the standard a long time so whatever the basis, it is lost as ancient history. A reasonable assumption (since it is allowed for existing systems, thus must still work) is that the 1/2 NPT unnecessary restricts the flexibility of a system that already has a higher flow demand than typically provided by K 5.6.
