It was great that the tech had all his own supplies and did not need to ask me for a bucket, or rags or towels to clean up with. (I've had that experience with several other plumbers.) I also loved that he cleaned up (sprayed down with cleanser) under the sink when he was done, and that he wore shoe covers in the house. The cost "was what it was," and was not a reflection of the tech. Two suggestions: use cold water when testing, rather than hot. (I had very little hot water when he left.) Also, pls be careful about touching the doorknob with soled gloves still on, as this germifies the doorknob. Overall, great experience!
