Finally, when our house was built, we installed a pressure tank. *The

cost of this tank and it's related controls, but I know it was over
$1,000. *I also know that our neighbor did *NOT* install one of
these. *My question is this... *Is our neighbor benefiting from our
pressure tank? *Besides lessening wear and tire on the pump, is it
also improving the pressure for our neighbor's house, too? *(The tank
is located in our house's mechanical room.) *Is this something that
our neighbor should be compensating us for?

If the tank is just connected to the incoming line, then the neighbor is
probably benefitting too. *When he opens a valve in his house, the water
will come from your tank, flowing back from your house to the junction
where his water line comes off, until the pressure drops enough for the
pump to turn on. *But this isn't ideal for him (there will be a pressure
drop through all that pipe) and certainly isn't ideal for you (you're
providing water from your tank to his house).

A partial fix for this is to put a check valve between the incoming pipe
and your house including the pressure tank. *That way, water that has
made it into your tank stays in the tank, for your benefit, and your
pressure doesn't drop suddenly when the other guy opens a tap.

But this may make the pump run more often than is ideal. *The solution
to that is for your neighbor to add his own pressure tank, at his
expense. *If he's not willing to do this now, when it's clearly mostly
for his own benefit, how willing will he be to pay half the cost of a
replacement pump when it fails?

Good job at inventing new problems that haven't been stated and have
nothing to do with the question.
