Instructions How To Assemble The Float And Arm To
The Franklin BL Valve And How To Adjust The Valve
The Franklin Valve is already attached to the drinker. The float and arm assembly is with the
hardware kit. They are packaged separately to prevent undue wear to the valve caused by the
arm bouncing up and down during shipping.
The float and arm are attached to the valve by a thumb screw. The float can be positioned
either closer or further away from the valve (see photo below left for the two float positions).
Further away increases the shut off force of the valve. However depending upon which drinker
is being used, the closer position may be required to maintain proper clearance for the float to
the side of the drinker. A clearance of at least 1/2" should be maintained to ensure smooth
operation of the valve.
When attaching the float arm to the valve, be sure to attach the arm to the correct side of the
valve. The grooves on the valve and float arm must match. Please note that the valve has
coarse grooves on one side and fine grooves on the other. The fine grooved side is used with
the float arm (see below right for details).
To adjust the water level in the drinker, loosen the thumb screws and position the float and arm
so that the valve is turned off when the water is at the desired level (see photo below). It may
take a couple of adjustments to get the correct level (1-1½" below the top of the trough). To
speed the adjustment process, remove the drain plug and drain a little water out so that the
valve turns on. Put the drain plug back and let water fill until the valve shuts off. If the level is
not correct, repeat the process until the correct level is obtained and then replace the float
cover. Your drinker is now ready for use.
