This unit comes with everything you need for a self-contained shower sump. Just plumb it to your shower drain, and then overboard or to a holding tank.
The unit automatically turns on after the shower water starts, and shuts off when the shower water ends and the sump is empty. Activated by a Rule-A-Matic® float switch powering a Rule 500 clog-free centrifugal pump.
Rule Shower Drain systems are available in two pump capacities - 500 gph and 800 gph. This unit is the 500 gph model.
The 500 gph model has one 1-1/2" inlet port, and a 3/4" discharge port.
The 800 gph models have three inlet ports which offer a combination of up to three different inputs (shower, sink, etc.) with inlet hose sizes of 3/4", 1", 1-1/8" and 1-1/2", as well as a 3/4" discharge port.
Other features of both units include:
• Clear screw down cover
• Removable strainer for easy cleaning
• Internal check valve to prevent back siphoning
• CE marked
• Dimensions (500 gph model 97): 8-1/4" x 9-1/2" x 5-1/2"
Sump needs to be installed so shower water drains into it by gravity.
