When we set out to reinvent the manifold, we had speed, green, and toughness in mind. We live in a world where most contractors still build up their manifolds by hand, using PVC, primers, and glues. The rationale is that it's fast and cheap. But is it really? Our Hydro-Rain time trials show that even a fast contractor spends over 13 minutes to build the valve nest out of PVC. Hydro-Rain's HRM 100 manifold takes less than half that time. During the course of a year, a typical medium-sized contractor will waste over 65 hours of time “ more than a week and a half of productive labor “ going with the fast and cheap method. It's one of those cases where what looks like a savings, actually ends up costing you.
