Webgradually decrease out with the pumped water, therefore it needs to take the air supply into the pump body through a snifter-valve. In its implementation, this snifter-valve valve is generally only a hole with 1 ÷ 2 mm diameter at a distance of about 2 cm below the height of delivery valve of the hydraulic ram pump body, as shown in Figure 1. WebThis valve keeps water from leaving the pressure tank in an attempt to head back into the well each time the pump stops. Watch out: when replacing the valve stem core in a Schrader valve that is serving as an air admittance valve on a drain-back system, be sure you obtain the proper low-pressure valve core or valve stem from your plumbing supplier.
WebUSE ECCENTRIC REDUCERS ON THE SUCTION SIDE Consider using eccentric reducers on the suction side of the pump when a pipe size transition is required. Install the flat side of the reducer on the top when fluid is coming from below the pump. If the fluid comes from the top, the flat portion of the reducer should be mounted on the bottom of the pipe.
