That's excellent advice. I'll tell my neighbor. My pipe coming down the hill is only 2" so unable to pull anywhere near the vacuum that 6" pipe did.
Reporting back. My good friend is a maestro with his Bobcats, so he made a pad MUCH higher on the hill behind my house. The plan is to get away from the pressure pumps and tanks at the houses. I calculated about 38 PSI peak, with some pressure drop due to friction and load. My current pump uses 30 PSI as the lower threshold, so I'm hoping to exceed that under a load of a shower and maybe the sprinklers. I'm probably delusional haha.
Anyway, here's the pics. I think the tanks are about 80 feet above the floor of the house, and the tanks will have at least 5 feet of water in them. It's good to have capable friends with nice tools. Now to rent a trencher and get some pipes in the ground.
Tanks waaaaay up on the hill.
The very beginning of the road. He found some clay in the digging for the pad and used that to compact the road later. It's very well done.
Looking down the new road. Blue Oaks everywhere !!
Getting the pad level. He used a laser level and got it to within about 1" over the 10 x 20 pad.
Motoring the tanks up the road.
6" diameter vents are available at Scotts Valley Sprinkler (who are suddenly helpful and reasonably priced, now that Scarborough took them over), and from Jeff at Make-A-Buck-Tanks in San Jose. I've heard horror stories of what happens when a fire engine hooks up to a 4" line and hydrant, starts sucking, and quickly collapses the tank.make sure YOUR tanks are vented adequately....
