Won't Leave Home Without It!

Once you have this system in your RV you'll wonder how you survived without it! I installed one in a newer travel trailer (2007 model year) which has always had objectionable tastes present in the water. These tastes were caused by the fresh water tank and 98% of the plumbing system being plastic, sanitizing of the water system using diluted beach or other chemicals, and some RV parks with high mineral and sulfur content in the water. This Culligan system looks beautiful, works great, and it has completely eliminated ALL tastes in our drinking and cooking water. With the proper tools, installation was a snap. The most obvious installation consideration is if your RV sink lacks an appropriate mounting hole, you'll need to drill one yourself. I had to do this through a fiberglass sink and wooden counter-top. No problem. I've read reviews elsewhere which complain about low the water flow from is this particular filter system. We have a similar water filter system made by GE in our home, and trust me it's no different. These systems are not designed for high flow. The flow is quite adequate for the intended purpose: filling up a glass of water, a coffee pot, or a cooking pan. Be realistic... you won't be taking a shower under this faucet!

Installation is a breeze. Like that it filters my water. Only thing that is a drawback is that the flow is kind of slow. But I still would buy it again.
