New Water Line from Meter to House

DaymonSeptember 27, 2011

We are clearing a lot for a home and need to run a water supply line from the meter to the house. The approximate distance is 1000 feet. There is good water preassure in the area thanks to a water tower close by. I am going to use PVC, and was thinking 1" would be ok, but was told by a friend to use 1 1/4". Whats the best way to do this? It is a 2 bathroom 2400 square foot home, nothing major for usage, just normal appliances and bathroom uses. There is not much elevation change, maybe a rise of 4' at the most from the meter to the house. We are in South Carolina and i am not sure where the frost line is, but i am sure i can find out locally before hand. Thanks for any help.

Use flexible line that has no joints of whatever type the AHJ will allow.

I agree with Brickeyee on the flexible line. You might be able to get it in 500' rolls. There will probably be a choice on stregnth of the line and I would spring for the heaviest. And you should find the frost line and what the local code is on burial depth so that you don't get a freeze up.

For single family residential service code requires that the water supply line must be sized to supply 100% total fixture load, where the fixture load is determined by the code table for individual fixture demands.
Individual fixture demands per code table:
BATH = WC 3, tub/shwr 4 & lav 2 = 9gpm x2 = 18gpm
Kitchen- Sink 2.5 & DW 2.75 = 5.25gpm
Laundry 4gpm
Hose Bibb 5gpm
TOTAL 32.25gpm ( round to 30gpm)
In a 1" plastic pipe the friction head loss is 0.2869psi/ft and the run is 1000ft for a total friction head loss of 286psi loss.
at 1-1/4 the friction head loss is 0.0702psi/ft x 1000ft = 70psi loss.
At 1-1/2 the friction head loss is 0.0322psi/ft x 1000ft = 32psi loss.
For a 1000ft run the preferred size would be 2" pipe which would yield a friction head loss of 0.92psi/ft x 1000ft = a loss of 9psi below the static head pressure at the meter.
(Loss based up using PE plastic pipe)

Have you thought about yard watering? Would you ever want to put in a sprinkler system?

The pressure losses shown by lazypup are at the calculated flow of 32.25 gpm. At lower flow rates, the pressure loss is lower. I suspect that the flow rate of 32.25 gpm will be seen very rarely in your situation.

It doesn't matter if it never sees that peak load, code requires the line to be sized to max and in most jurisdictions you can not even pull a permit until you do the math.
