Clean septic system installation work. This photo of a pressure distribution septic system’s header manifold is a great example of what clean, professional installation work looks like. This was installed by the guys over at Kat Trax, and we really like their work. Just because it gets buried, doesn’t mean that the work should be sloppy. Attention to detail matters, and we always recommend installers that pay attention to the little details as well as the big ones.
