I contacted Jim via Thumbtack to help me upgrade my 4x10 whole house sediment filter to a water system that would get rid of the iron and acidic PH in my water. He contacted me within minutes to schedule an in-person visit. Based on the hardness and PH that was present in my well water, he recommended a softener and an acid neutralizer. I found Jim to be trustworthy and very knowledgeable about water solutions and would recommend his services to anyone in need. It’s been a couple of days since the installation and my water has drastically improved already.
