The surface should be clean and level.
NOTE: Any solder joints being soldered near the valve must be done before connecting any piping to the valve. Always leave at least 6" (152 mm) between the control valve and joints being soldered when soldering pipes that are connected to the valve. Failure to do this could cause damage to the valve.
Tighten the retaining nuts hand tight, ensuring that the fittings are not cross threaded.
Use an adjustable wrench to ensure they are tight.
NOTE: All piping should be secured to prevent stress on the bypass valve and connectors.
Teflon tape the threads and tighten the fitting using the proper tools.
NOTE: Be sure to secure the drain line. The system will drain with force and it should be secured to prevent a leak. Hose clamps should be used to secure the drain line at the connection points.
NOTE: If installing a 20 GPM system (081-MIF-10-250), it is recommended to use a 3/4" minimum drain pipe to ensure proper performance during backwash.
This linear pipe should have a physical "drop" toward the drain (1/2" : 10'). The goal is to have a gravity drain without much back pressure when traveling long distances. NOTE: A direct connection into a waste drain is not recommended. A physical air gap of at least 1.5" should be used to avoid bacteria and wastewater travelling back through the drain line into the system.
