Technician Taylor arrived on scene to investigate reports of a leak where we have worked previously. We were out approximately 8 months ago and replaced six cartridges on three sinks in the home. All three sinks are located in the two bathrooms in the home and they all use the same cartridge. Only the cold cartridge in the hall bathroom is dripping. Technician removed handle and was able to snug down the cartridge a little tighter. Technician found the dripping has stopped.

Technician instructed client to keep an eye on it to ensure it does not return. Technician collected signatures and pulled off
