I have a new kitchen faucet by Price Pfister. A Bacharach model, IIRC. It
has one lever, left and right, up and down to adjust the temp and flow.

My problem is that when it is used at a slow water flow rate, the weight of
the handle causes the handle to drop and shuts off the water. I just pulled
the setscrew and handle, and I cannot see any adjustment on there. Just a
large nut down inside a collar that would be hard to grasp.

I threw away the directions. Does anyone know how to fix this?
