We provide detailed specifications along with a material list that includes all necessary components to complete the intended project scope, including; low flow plumbing fixtures; “Pex” hot and cold potable water distribution; venting; water heaters; and PVC waste lines ready to install with “snap lock” fittings for seamless installation, etc. Typical plumbing distribution would be located and placed “in-slab” by the plumbing contractor with materials provided in the plumbing package by Global Eco Housing.
