Great replacements!

Installed easily into the system. Once flushed my water tastes just fine. These are the exact replacement units for my system so I did not expect any problems. After installation you have to flush the storage tank three times. It takes two to three hours to refill my storage tank so the process is tedious, be patient and read the directions! I suggest filling a container with filtered water before you start, that way there is some on hand. My directions suggested taking this time to check the pressure in the storage tank. For my system it should be 5 to 7 PSI in the tank. The pressure was low so I "carefully" pumped it up at the end of a drain cycle. It will push any remaining water out of the tank so you may have to pressurize several times. The tank MUST be empty for the final pressurization. I have much better flow now that I did that. One other thing, if your system is hooked up to your ice maker, isolate the ice maker before flushing the tanks 3 times. If you don't do this then you will need to flush the line going to the icemaker. The reason for knocking off one star is the price. I feel that the price could be a little more reasonable.

As advertised. Cheaper than what the companies web site sells them for. Hopefully they aren’t “fake”?

good system to ashier family has great drinking water , much better than buying bottled water.

Low price.
