WATER SYSTEM
The water system consists of three primary elements: 1) Water Delivery System, 2) Spray Bar Assembly; 3) Pump.
Troubleshooting of this system is fairly simple.
The Water Delivery System consists of two assemblies: A) The Water Inlet assembly and B) The Plumbing assembly.
The Water Inlet assembly is made up of four components: 1) The water supply connection hose, 2) The bulkhead fit-
ting, 3) The float valve connection hose and 4) The float valve.
The Plumbing assembly consists of three elements: 1) Riser (PVC components), 2) Drain Valve, 3) Spray Bar
Adjustment Valve. The 16 inch model has no riser or valves.
The Spray Bar Assembly consists of two components: 1) Spray Bar, 2) 4 foot connection hose.
The pumps that actually move the water through the delivery system are discussed in the charts below. These charts
indicate the major symptoms of problems that may be encountered with the Water System components.
