Upon arrival customer stated she had a lot black sludge buildup on her faucets. Informed the customer that it happens because of how hard the city water is I informed her we could install a whole house filtration system. Gave customer two estimates for the whole house filtration system. Customer stated she is going to talk it over with her husband. Customer also stated she had a tub and a shower she need the drain cleared. Gave customer estimate to clear shower and tub drain. Customer approved estimate. I ran my air snake on the shower and was able to clear it and as well as the tub. Both drain are draining properly with no issues.
