I am very pleased with the zero water. i have had it for 3 years and it just going bad with the system i have. but i cant find the system i have please help. it has saved thousands in buying botted water. to have it as a good system you have to use it alot and not have the water sit. replace the filters every 2 months it helps. it takes the chemicals ot of the puplic water which i have and it makes it taste better.then as the water goes in then it good to drink today.
