I have had good experiences with Forster Plumbing Co, Harford Rd. They installed all the plumbing in my row house restoration and at a later date, replaced the cast iron soil pipe, which ran across a wall of my back building, then to the street. I had it buried under the basement floor. I also hired them to do some work at my church, which was done swiftly. All the work was done at a reasonable cost.
