Customer had a drip on the laundry valve when opened. I tighten the packing nuts on both the hold and cold side of the washer box. Both valves are gate valves and are older and probably from when the house was built in 1992. Customer also has gate valves at every fixtures just not the two his and her sinks in the master bathroom. Left estimates to replace all the valves add an expansion tank and to do a rebuild on the Kohler toilet in the hallway bathroom
