This Solenad Vacuum Valve is required where electric toilets are installed below the waterline and a Jabsco vented loop is intalled in the inlet pipework. The extra suction of the electric toilet will open the valve in vented loops and prevent the flush pump from priming. The solenoid valve is wired into the toilet's on/off switch. It closes when the toilet is operated ensuring pump prime.
