Had a contractor come out today for in-floor heat not working. I have 2 zones each with Rehau manifolds supplied from a single pump and neither zone worked. Contractor felt the pump had failed and replaced it only to discover that the system still did not work. After much consideration, contractor realized that the manifolds had been installed backward and suggested that this is the problem and that this bad installation had led to the pump failing. However, system had been functioning properly for 16 years before this. Contractor wants to replace the manifolds as the next step, but this seems silly to me. Is there contractor's theory rational? Anyone have another idea?
