Now, unroll the colored tubing from the kit. The yellow tube usually goes from the valve to the first filter housing. Push it into the push-to-connect fittings—they click when seated. Seriously, it’s that easy.
The blue tube feeds from the filters to the faucet, and the black tube goes to the drain (yes, that tiny black line). For the drain, you’ll clamp a little saddle clip to the sink drain pipe, then push the tube in. It sounds complicated? It isn’t—it’s just two minutes of gentle wiggling.
A Quick Check
Before you rejoice, double-check all connections. Are they snug? No kinks in the tubes? Perfect. You’ve basically built a water treatment plant the size of a shoebox.
