Chris from CK's Plumbing and Backflow installed a tankless hot water heater for me. The service was fast, professional, friendly, and extremely affordable. Chris also made sure I received all of the energy tax credits and rebates available to me. He was a lot less expensive than the gas company (this was a natural gas tankless water heater) and I feel his customer service is better. I would recommend CK's Plumbing and Backflow to anyone neededing plumbing, gas, or backflow services.
