Product review (4 stars): Whole House Triple Crystal Quest
Shipping:
  well packed and protected but took longer than I was expected.
Installation:
  this system is larger than I expected.
  with a professional plumber installation was difficult and required a second trip out to complete.
  minor leaks with both the water inlet and outlet and with one of the cartridges.
Recommendations:
  check your water pressure.  You will need a reducing value if your house pressure is over 60.
  why can't they manufacture these things with brass or stainless fittings in the water filter head?
Performance:
  works as I expected.  Happy with water taste and filtering of the system.
  expect a drop in water pressure through out the house.
