Sam Simcox at Fluid plumbing trained with his dad, a licensed master plumber in Blue Bell, PA, from childhood. He provided a no-fee consultation that was quick and accurate... he was a second opinion... the first bigger-name company got it wrong and tried to sell me all sorts of products and services related to the wrong diagnosis! Would have cost over $4K!!! Sam returned the next day with the required part (a faulty pressure reducing valve) and replaced it at a very reasonable rate. Voila, just like that no more pressure problems in our house! You can't go wrong with him, he doesn't upsell or misdiagnose and is quite honest and focused at getting the right problem solved.
