We have a 10 GPM pump supplying 2 houses without issue. I'm installing a system to supply one of those two houses but I want to be able to reciprocate by being able to supply next door in a pinch - Although it's just two of us and our peak demand is at most 3-4 GPM.
I believe the rule of thumb is 1 gallon per water outlet/fixture. Between the two houses there are 33 outlets. I estimated the most that could be used a one time is 19 with the maximum likely at 10. I split the difference and decided on 15 GPM.
Then I went shopping and the real world sent me back to Terry Love There's a huge difference in price when you talking 15 GPM. So now I'm thinking, a 10 is doing the job now so why reinvent the wheel; or should I consider a 12 GPM?
