Most water filtration products regardless of the manufacturer should be installed by licensed plumbers in order to not void the warranty. There are however a few products manufactured by Crystal Quest that a plumber may not necessarily be needed including:
- Countertop units
- Shower filters and Bath balls
Products recommended to be installed by a plumber are:
- Undersink units
- Water Coolers
- Refrigerator In-lines
Crystal Quest products that absolutely must be installed by a licensed plumber in order not to void the warranty and to prevent damage are:
- All Whole House units
- Commercial units
- Reverse Osmosis units
Again, all Crystal Quest water filtration products should be installed by a licensed plumber to ensure proper hookup, to avoid damage and not to void the warranty. The installation of all Crystal Quest systems may seem simple enough, but when you are connecting to and cutting into existing water lines, it can be dangerous and there my be local codes that only a licensed plumber would know about.
