The AquaTru Under Sink reverse osmosis system is designed to be user-friendly, and it includes a comprehensive installation guide along with a helpful installation video, installation guide and installation video. These resources are intended to assist you through the setup process step by step. However, it is important to consider your own skills and experience when deciding whether to tackle the installation yourself. For those who may not have a background in plumbing or who feel uncertain about their abilities to perform such tasks, we strongly recommend enlisting the help of a professional installer. The installation of the AquaTru system involves drilling into the plumbing pipes located under your sink, a process that can be quite challenging and potentially risky for someone who is not familiar with plumbing work. Hiring a professional can ensure that the installation is done correctly and safely, which can ultimately save you time and prevent any potential issues that might arise from improper installation.
