I had a water dripping from one of the out let pipes emerging outside from within the house. I contacted Indenpendence Plumbing. I dont't have much knowledge of plumbing. The plumber assessed the leaking problem and told me that he would charge $425. He then changed the pressure relief valve located in pipeline assembly just above my water heater in garage in less than 30 minutes. The cost of the pressure relief valve when I inquired in local Home Depo was not more than $40. I leave up to you when hiring this plumber.
