Jabsco Vented Loop Solenoid Valve

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