Vented Loop Solenoid Valve for 37010 Series Toilet When installing a vented loop in the inlet hose, it is recommended that a Vented Loop Solenoid Valve (37068-2000) is connected to the vent air inlet to ensure maximum electric toilet performance and prime-ability. Connect the brass port of the valve (remove plastic filter, if installed) with the air inlet of the vented loop. Wire the solenoid valve in parallel with the toilet motor by connecting one side of the solenoid to the toilet flush switch and the other side to battery ground.

MF 844 Vented Loop - 1" Installing one of our vented loops will ensure that fluids will not siphon from tank to tank. Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve is designed to seal properly if particulate matter is present in fluids.  Specifications: Barb Size: 1" (25.4mm) Height: 7" (177.8mm) Width: 9" (228.6mm)
