Disconnecting a Hydrolock Fitting

Caution: Always turn your water supplies off before disassembling your faucet. With the supplies turned off, move your faucet’s handle to the “on” position to relieve pressure.

  1. Find the two white plastic tabs at the end of the Quick Connect fitting. Squeeze these tabs together with your fingers or pliers. As you squeeze these tabs they will become pushed into the black plastic housing. This will cause the white button on the opposite side of to pop out a little.
