Pump Vaults house and protect the pumps and plumbing of underground water storage and circulation systems. Vaults are rotomolded of virtually indestructible polyethylene for long, worry-free service. Sized to accommodate multiple pumps, Vaults also house Ionizers, Check Valves and Auto Fill Valves. Tight fitting covers and generous openings provide easy, secure access to pump and plumbing and accessories. Pump Vault Extensions increase the height of the Vault in deeper, larger basins, with each extension the height of one Eco-Blox. Flat panels and multiple cut lines allow almost limitless plumbing options. Easily accommodate any project from mighty waterfalls to rainwater cisterns and downflow bogs.
