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.
Strap Wrench
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.
