Customer had two showers that was slow draining upon arrival. I ran water and tested and saw that the showers was draining slow so I recommend it to snake the shower drain to remove any hair and lime scale next I removed the drain cover for the master shower and ran my drain cable down the drain to remove hair and after testing, the drain was flowing perfectly and I remove the small filter that they have to clean out every few weeks and let the customer know and they were fine with that , next I went upstairs and clean the daughters bathroom shower drain that was completely clogged with hair after running my cable I removed and tested the drain and then the shower was working perfectly
