stress.
• Use pipe, tubing or reinforced hose to make dis-
charge connection. Material selected must have
sufficient strength for operating pressures.
• Discharge pipe should be sized so that flow velocity
is below 8 feet per second.
• Use ONLY non-slamming check valves to prevent
hydraulic shock (water hammer).
• Use gate, ball, or butterfly valve for isolation. Valve
should be full open during operation.
• Maintain proper pipe size throughout discharge
system, using as few elbows and tees as possible to
keep friction loss to a minimum.
• Install pressure gauge after reducer as shown to
check operating pressure or shut-off head.
