Ah! Some real reasoning. Yes a 2" line is adequate for 3 houses.
They now have the equivalent of about a 3 1/4" line. The size of
the
pump outlet does not play in the problem. The pump feeds the
pressure
tank which feeds the houses. Only if the total draw exceeds pump
capacity is there a problem.

In this particular application there is no pressure tank. The well
pump fills a
1500 gallon storage tank and is controlled by a float valve. A
booster pump
draws water from the storage tank and supplies water directly to the
houses.

It would be hard to imagine the houses drawing more than 30gpm
combined at any
one time and that number seems well within the capacity of a boost
pump.


My hose faucet running full blast puts out about 15 gal/minute.

No pressure tank? Does the pump run full time?

Connecting the 2 pipes together before splitting to go 3 ways would
help assure that noone gets short-changed on water.

If there is a problem, increasing the pump pressure should solve it.
(Bigger pump) I wouldn't expect it. Without watering usage, high
demands should be short lived. A pressure tank at your house could
solve that.
