   Turn off the pumps and it takes [u">a long time[/u"> for the pressure to drop to zero. Water, unlike air does not compress.

   Scott,
   
   Well, at least you know you don't have any leaks. Fast ones, at least. How long did it take to get to zero?

   as long as the system isn't blown out, I've never seen mine below 14 psi. That was with pumps down for 2 weeks. My pump station is at the lowest point on the course, only because that is where the water source is.

   We've never tried it, but my Assistant estimates it would take three hours. So maybe not [u">that long[/u">. We have very minimal elevation change here.

   Aren't many things more fun than shoveling through locked up angular rock, which is what you'll be faced with if (When, actually) you are faced with finding the leak.

   This practice is normal in the sewage and city water supply. Recommendation by North American Pipe Company states:
   "EMBEDMENT
   The use of proper embedment materials is very important to
   trouble-free operation of the pipe system. Avoid using
   angular rock larger than ¾ inch (20 mm) or rounded rock
   larger than 1½ inches (40 mm) for embedment."
   
   Normal practice on a golf course is to embed the pipe with sand. Sand is easier for us to dig up with shovels when we have those leaks plus the last thing we want is a blow-out and have gravel all down the middle of our fairway.........

   More common in our area of the country is to back fill municipal pipe with sand. The trench is over-dug, a layer of gravel is placed at the base of the trench to achieve the desired invert elevation, then the pipe is back filled with sand.
