Reverse Osmosis/Diatamaceous Earth

[Daniel]

A RO large enough to supply an entire house wouldn't be cheap (several thousand dollars). Plus you would have maintanence to do on it. Its pretty much pointless to RO catchment water since it is nearly mineral free already. Also you would be wasting a lot of water which wouldn't be good for a catchment system either. As for bugs, UV is more than sufficient to take care of anything you might encounter, if you have a properly sized one. It sounds like you have something unique. If you do infact have a large RO it will be big, have lots of stainless steel, and cartriges that you have to replace. Pumps are easy to identify, there should be no mistaking that. You may have some kind of cholrine injection system or Ozone purification system, which could be what looks like a RO. As far as the pump being in the tank, there is nothing to be afraid of. In fact all of our pumps go under water. If you cant figure your system out let me know and I can help.

A hui hou,
