In my neighborhood we have a well-based system which pumps water to holding tanks a little uphill from my house. The vertical drop isn't very much so the incoming pressure is low ~10psi. We have an Amtrol RP-10HP followed by a 5 micron 4.5" x 20" filter then a Aqua-Pure System AP904. The pressure to the house is low even with new filters and the pump causes cavitation when running. I need to come up with a system that provides better constant pressure and good filtration. Here is what I'm thinking:
filters (maybe with a ~15 micron, 5 micron, then carbon filter) ->
Amtrol WX-350 119 gallon pressure tank ->
Amtrol RP-10HP presurizer
It seems like this could work but there is a risk we drain the 119 gallon tank faster than it can refill, which would causes issues. Would this work to solve our pressure issues? Is there a better setup?
