Hi tinouthouse and welcome to The Plumbing Page at ANHD.com.

what is the average cost per linear foot for a 1 inch water line installation.
To give a estimate we need information and you have given us zip.
Length and depth of trench? Backhoe or hand dug. Cost of material and all fittings? Union or nonunion labor? How many men>? Hourly wage? If you can answer those questions we can come up with a ballpark figure, Back to you. BTom
