Installing your new Shell Water System will vary, depending on your current plumbing situation. Give us a call and we can help you with your specific situation. If you have pre-plumbing for water treatment in your home then this could be a simple DYI. If you do not have accessible plumbing this is NOT a DYI project. All installations are different depending on the main water line and where it enters the home. We suggest hiring a professional. This is plumbing and should be done by a licensed professional. We can help you find someone in your area!
