I had a plumber from a company in Baltimore MD. I knew it was a valve, my dad was a plumber.  The man told me that he needed or order a 900$ valve because it was iron free.  WTF As soon as I said I have to ask my dad he is a plumber, he said Oh I can get a cheaper one for 600$ that was the total bill install and all. WHY When they see a single woman does the price go up 300$?? All-State Plumbing was the company
