This is typically an installation or filter-capacity issue. Check the alignment, O-rings, and that plumber’s tape isn’t obstructing flow. How do I install Duo? Between the shower arm and shower head—no tools required. When do I replace the filters? Every 5–6 months for one user under normal conditions. More challenging water conditions or heavier use may require more frequent replacement. Weddell Duo FAQs Why is my water pressure lower? This is typically an installation or filter-capacity issue.
