Need Help with Main Water Connection - 700 Feet Distance, 130ft Elevation, 1Inch City Water Connection

[kasa]

Hi
I have read many posts regarding this and learned a lot but not able to conclude so trying to post this and get help from the community. Thanks in Advance.

City Water Line: 1 Inch
PSI at the Connection: 80PSI
Distance from City Water to home : Horizontal distance : 750ft
Elevation is : 130 ft
Home Has : 3 Full Bathrooms ( Kitchen Faucet, Dishwasher ) - Washer & Dryer
Planning to use 2Inch Pipe - Any Recommendation on which type of pipe Poly? Schedule 80 PVC or Copper ?
Location : San Jose City California

Do i need a Tank & Booster Pump at the bottom of the hill near to the water connection?
Can i Just have Booster Pump Near the Home / Middle ?


Thanks in Advance!!

You will lose 56 PSI going up the 130'. Starting with 80 PSI this will leave you 24 PSI at the house. That is not enough pressure to be happy with, but is enough to feed a booster pump up at the house. Something like a J10S with a PK1A would give you strong constant pressure at the house.

Thanks for the quick response.
Will try go with this route and if not we can fallback to installing the Tank at the bottom as last resort.

Few more things to confirm ?
- Distance of 750ft will not have any impact ? or using the 2inch will balance it out ?
- 2 inch Pipe - Any recommendations on this ? ( will be like 1 or 2 feet deep undergound )

Pipe just needs to be below the frost level for your area. Won't be much friction loss in 2" pipe. With a booster at the bottom you will need a different kind of pump and 56 PSI more pressure. Up top a 40/60 switch will work. Down below you will need a 90/110 pressure switch, and a pump like a multi-stage that can do that much pressure. The tank also needs to be larger at higher pressure. Up top the 4.5 gallon tank is large enough. Down below I would use at least a 44 gallon size tank.

Do i need the big tank or i can just use the Booster Pump ?
