I am building a house for my parents 230' up the hill (about 100' of head) from my current home. Currently I have a drilled well at 230' of head with a 1hp pump and an 85 gallon bladder type pressure tank set at 30/50. This tank has 10.7 gallons draw down. My house is about 100 ' from this well. Could someone please guide me on hooking up the new house to the same pump..if possible? My current water pressure is good, but when I ran a hose up the hill to water cure the slab, the pressure coming out of the hose was a trickle. A friend told me to relocate the pressure tank and switch to the top house and there would be no problems. I am concerned bout water hammer when the water comes back down the hill if I do this. Could i locate a csv just before the tee to go up the hill and solve the problem? Do i need a pressure tank at each house? Can I leave the switch at the lower house or do I need to move it up the house? Thanks for any advice.
