Here’s a reality check: after 12 to 15 years, the plastic housings can become brittle. The seals might crack. Maybe the system starts leaking from a spot you can’t fix. At that point, it’s not worth bandaiding. You’d be amazed how much better a new model performs—faster water, less waste, maybe even a touchless faucet. It’s like upgrading from a flip phone to a smartphone—everything just works smoother.
