Customer stated the hose bib leaks even when shut off and the shower upstairs drains slow. After taking a look at the hose bib and shower also found tankless had not been serviced and was going on two years old. Gave customer estimate to replace the spigot, cable the shower drain, and flush the tankless. Customer approved estimate. Replaced the spigot, ran cable through the shower drain upstairs and pulled back hair. Also flushed the tankless for an hour. Spigot is now working, shower upstairs is draining properly and the tankless has been serviced this year. Everything is working properly and no leaks upon departure.
