If a pump becomes air locked it will continue to run but not push water, causing the pump to eventually burn out. This trapped air blocks the pipe when the pump turns on preventing water to be pumped beyond the trapped air. When a check valve is installed on the discharge pipe, air can be trapped under or behind the check valve. This hole is normally drilled a few inches above the pumps "on" level. "Why is a 3/16" vent hole pre-drilled into the discharge tube?"Ī.A 3/16" vent hole, also known as an air bleed, is drilled into the discharge pipe located in the basin between the pump and check valve to prevent the pump from becoming air locked. What makes them 'premium'?"Ī.The "Premium" Polyethylene Structural Foam basins have torque arrestors molded into the bottom of the basin to keep the pump in place during operation and to prevent damage to the pump during shipping. "We noticed some of the basins are listed as 'Premium' Polyethylene Structural Foam basins. The installation for each unit is similar the check valve hinge must be at the top. "Can I mount the check valve horizontally?"Ī.It is normally recommended that the check valve (or check/ball valve combination) is mounted vertically, however each can be mounted horizontally. In this case it is a collar attached to the bottom of the basin to reduce or eliminate the basin from being forced out of the ground when the water table is high. The abbreviation "AFD" stands for Anti-flotation device. Premium Polyethylene Structural Foam w/ AFD & AlarmĪ. Premium Polyethylene Structural Foam w/ AFD dynamic head pressure - maximum vertical lift (shut-off) 18 feet - click here for pump dimensions - click here for more detailed pump flow rates. 4 HP - 115 volt - mechanical float mounted to pump - flow rate 90 ft. 18" diameter x 30" depth basin has 30 gallon capacity.Ĭlick here for helpful information about installing these Zoeller Outdoor Pre-assembled Sewage Systems. Centerline of hub is located 10-1/2" from the top of the basin. Premium systems include an anti-flotation device, torque stops and a 4" snap-in hub. A 3/16" vent hole is pre-drilled into the discharge tube. Rated for outdoor burial, these basins have a 2" discharge on the side and include a 4" inlet pipe seal hub. All of the check valves sold separately below can be installed on vertical or horizontal pipe.īasins are made of Polyethylene Structural Foam with a solid Polyethylene Structural Foam lid. The check/ball valve combination allows you to stop backflow from flowing back to the sewage basin while servicing it.
