Too much pressure loss for a whole house system
** Note from AFW: The blend of activated alumina we use has now changed and the flow is normal through these filters as you will see with future orders** These filters do what they claim (at least the sediment and GAC85, I haven't had my water tested for flourine since I installed the system) but they drop the water pressure so much that a flushed toilet or running shower (even with a low flow head) results in little more than a trickle from any other faucet in the house. The issue seems to be mostly caused by the alumina filter which has led me to separate my 3 stage system into a 2+1 arrangement with the alumina filter only feeding my kitchen water supply for drinking water purposes. Since installing my system I have replaced all three filters twice. The initial set worked fine but both replacement sets have had problems with the alumina filter. If you plan on using all three filters, plan on either losing a lot of pressure or reworking your plumbing to separate the alumina filter so it only feeds specific locations rather than the whole house.
