Hey all,
I'm going to be starting an irrigation system plan this winter and I just got done replacing some piping in the house to ensure that I have the maximum amount of water pressure and flow available in the house. Can I get a gut check that these numbers are okay?
I open the outside spigot to 100% and let the water flow for some time. I watched the dial on my meter spin and recorded the diffrence in volume and the time it took. I came up with 12GPM @ 44PSI-dynamic (measured on a faucet in the basement while outside spigot on) and 76PSI-static (measured on outside faucet) with nothing running.
Here's what is between the water main and the spigot:
* 8" water main in the street
* 10' of size unknown lead pipe between main and curbstop
* curb stop, unknown size
* 35' of 3/4" copper between curb stop and angle stop in basement installed circa 2010
* angle stop, 3/4"
* 8" of 3/4" copper between angle stop and 1/2" nipple
* 3" of 1/2" nipple to meter
* 5/8" meter, install date unknown
* 3" of 1/2" nipple after meter
* approx 10' of 3/4" copper and through 2 full port 3/4 sweat full port ball valves installed day or two ago ))
* 12" freeze proof spigot, appears to be 1/2" in size.
What do we think? Okay? Seems about right?
Thx,
Jason
