A:Answer Yes you can, I did replaced my line with a longer line and it considerably reduced my foaming problem. I have the single tap, I imagine it's the same as the dual. Remove the top cap on the tower. Than you unscrew the faucet from the tower (they have a tool for this, I did without but it was harder). To detach the line from the fauce remove the pex clamps that holds the line. Install your new line and clamp them like the old line was, you will need a tool to work with pex clamp (clinch clamp).
