What should I do if my single- or two-handle faucet leaks under the handle?
• Turn water off at the stops.
• Remove the handle. (For single-handle DIAMOND Valve models, also
remove the cap.)
• Use an adjustable wrench or channel locks to tighten the bonnet nut (on
two-handle models and single-handle DIAMOND Valve models), or use a
strap wrench to tighten the cap (on other single-handle models). If you
don’t have a strap wrench, put a towel over the cap to protect the finish
and use channel locks.
• Replace the handle.
If that does not solve the problem, you may need to replace the cam
assembly for a single-handle faucet with a ball valve (see illustration
on page 14), or the stem unit assembly for a two-handle faucet (see
illustration below). For single- and two-handle DIAMOND Valve models,
you may need to replace the DIAMOND Valve assembly (see illustration
below). Visit deltafaucet.com/customersupport for detailed instructions.
