After Paul produced the DIY instruction video for the Radiant Floor Company the company president had this to say: "..clear, precise, visually superb and with all the plumbing aspects presented in an easy to grasp step by step format. You've managed to convey a lot of potentially scary mechanical details in a non-intimidating, "I can do that" fashion. Great job!"
Bill Northey, President Radiant Floor Company
