The answer to 'hydro jetting not working' is that there are a few common causes, including blockages too tough for hydro jetting, improper hydro jetting technique, or issues with the hydro jetting equipment itself. Symptoms may include slow draining, gurgling sounds, or water backing up in sinks and tubs. Solutions can include trying a different hydro jetting approach, clearing the blockage manually, or calling a professional plumber to diagnose and fix the issue.
Hydro jetting is a powerful technique that uses high-pressure water to clear tough clogs, but it's not a one-size-fits-all solution. If hydro jetting isn't working, it's best to have a professional plumber take a closer look to determine the root cause and recommend the appropriate next steps. Attempting to fix the issue on your own without the proper knowledge and equipment can lead to further damage to your plumbing system.
