I found out the other day that the drain under my kitchen sink was leaking. While the problem was more like a slow drip than a leak, I was still concerned. I went to the local hardware store to find a solution. I was glad that I ran into a salesperson that knew what I was talking about.
The salesperson helped me find the replacement parts I needed. I took them home and found that it was easy to install. The problem is now fixed and I am grateful that at least there are a few people who know what they are talking about.
