Question: Must I have a water  softener to use this product?
Document: They are easy to change and they last about a year. I was surprised that with as bad as our water is, the filters truly did last a year before they needed changed. We use this water for a great deal of our daily needs so it is cleaning gallons upon gallons of water and still the filters lasted a year! Yes, best money we have spent in a long time, for a high quality product with perfect results!
Purchase this product watched the instruction videos and was very easy to install. The only issue we had was after the install flushing and testing for leaks we went out for a few hours came back and there's a small puddle under the kitchen sink. Nothing terribly bad and we were able to use a small towel to dry things up but make sure that you check the system a few hours to half a day after to make sure there is no leaks.
I mean like at someone's house who has really hard well water and has a whole house softener installed? Usually in this case, the kitchen sink has its own connection which by-passes the softener. Or this was the case in the house I'm thinking of. Water from the sink was hard, but drinkable. But water from the bathroom faucets? AURGHHHH! YUCK! So not pleasant!Well, for MY PALATE, that was the case here. But, admittedly, it was subtle.
Not only have these folks found a way to make the world's best water by taking out any impurities, but the minerals they add back must be magic because the woman who grimaced every time tap water touched her lips is now all smiles, all the time, acting as if the water flowing from our RO tap is the nectar of the Gods. And perhaps best of all from my perspective is that this unit doesn't produce the water at the dribble rate of most RO units.
I use it to water special plants and in my neti pot. I now prefer to wash my face in the kitchen as I can just feel the quality of the water on my skin. This has been a great purchase and has added value and convenience to my home.
We use it for drinking and cooking and never run out of water. The flow from the supplied faucet is fantastic. Everyone in our home simply love this thing! I will strongly recommend this to anyone who is serious about safe clean mineralized water.
This system has performed perfectly, and we have been using it daily for 1 full year. The water tastes great, and I love the fact that it actually is not DEVOID of important minerals. I'm ordering my replacement filter soon, and plan on continuing to use this system for a long time to come.
We shopped around in stores and on-line for a few months considering a RO system to use in our home. We only used the filter on the refrigerator up until purchasing and installing this system. It works great! The water pressure is strong and I even was able to order the refrigerator hook up kit from the company to tie it in to that system too.
of water dripping thru my faucet and told me that water is still being filtered so I can just put my storage contained or pitcher under the faucet and leave it there for a few minutes and it will be full, so I can still use the same, clean water, even when the tank was de-pressurized! Nice...I also changed the cartridge at the end of one year and it was very simple.
I researched water filtration systems for many days before deciding to pull the trigger on the Tap Master TMAFC. I am extremely happy with my choice. I installed this system back in February 2013 and wanted to use it a while before I wrote a review. I use the water from this system for all my water consumption/cooking needs.
