Community Tips

WarningKasa Team

Shutting off the main water supply is non-negotiable before disconnecting supply lines, as residual pressure can spray water into cabinets and create costly water damage within minutes. Most homeowners underestimate how much water remains trapped in the lines even after the valve closes.

Tool RecKasa Team

A basin wrench is essential for this job and cannot be substituted with standard wrenches -- the Crescent Z2 Basin Wrench ($12-18) features a pivoting head that accesses the tight space above the sink bowl where supply line nuts are located, saving 30+ minutes of frustration.

Cost InfoKasa Team

Budget $150-400 for a mid-range faucet like Moen Adler or Delta Trinsic ($200-350), but expect an additional $40-80 if existing supply lines are corroded or incompatible with the new faucet's connections, as replacing them prevents future leaks under the cabinet. ---
