Snyder Dominator ( brochure | low-pro install | pump version install )

These poly septic tanks are pre-plumbed with 4" SCH-40 inlet and outlet, sanitary tees, gaskets, and manhole covers. These low-profile poly septic tanks have a unique heavy-duty design, for those tougher installations. Top male ribs provide added strength against top loading. New bottom male ribs counteract high hydrostatic forces. Radial Reinforcement Bands and tie tubes provide superior radial strength. These tanks can be installed without water and can be backfilled with native free-flowing soil. All models of the Dominator low-profile poly septic tanks can be used as holding/pump tanks.
