Installing this unit was a snap. No problems. We filled the unit 3 times and drained it 3 times. Water was a little off, drained and filled it again and now the taste is perfect.
Somehow, the water pressure is low. Manual says to check for kinked line, no go. Tank pressure is at the optimal psi. Not sure what happened. I just may drain it again to see if I can get the pressure back up.
I would buy again and I have recommended it to a friend.
Good: I had a leaking faucet and a new one was sent immediately. Easy to install.
Bad: no alkalinity indicator, no instructions regarding alkalinity, there is no possibility to adjust the alkalinity.
