    just had a quick question. I am getting a new water softner and need a reverse osmosis system. I just wanted to know if you connect the r/o to a hard water line or a soft line that comes from the water softner. My kitchen sink is on a hard line so if it has to be soft that will require more work.

    Thanks from new guy. love this forum.

    you can use either one, but you will change your membrane and filters less often with soft water.

    I use soft water to supply my RO filter. We use RO water for all cooking as well as for making coffee. A kitchen sink and especially the dish washer will benefit from soft water. It is only the outside hose bibs that have hard water, and even at that, I take them off after the iron filter. I also have two aoutside hose bibs that provide hot and cold soft water for washing the dog.

    Thanks, so I guess soft water it is. I have the back hose on hard and the front is also on hard but the kitchen is on the same line as the front. So it might be easier to just make that front hose and kitchen soft. This way I can have soft in the front to wash the house and car, and keep the backyard hose as the only hard line in the system for plants and grass. Does any one have apec as a r/o system I have good things about it.

    Thanks.

    I would never connect an RO to hard water when softened water was a choice. There is no advantage and many disadvantages. Of course the degree of hardness (and other contaminants) directly relates the life of not only the membrane but also other parts and components of the RO.

    Thanks again, soft is the choice. I will only have one hard line the back hose line. The front hose will be changed to soft since it feeds the kitchen cold and the bar sink.
    Thanks.
