If this Valve is to replace an existing Fleck 5600 valve, then the existing By Pass or Piping Yoke will clip on to the valve. Otherwise you will NEED either a standard Noryl plastic piping connection in either 3/4" or 1" with all valves purchased, OR a By-Pass Option can be purchased separately.
NOTE: Valve Cover ( for outdoor use ) is an option you may want to order separately if you need one.
We include at no extra charge, a new distributor kit. This is part # MD1236. It is a plastic lower screen which can be cemented to a piece of 3/4" PVC pipe to construct a new distributor tube. Your old distributor could be slightly smaller than the ones now used by both Fleck and Autotrol ( old size 13/16", new size 1.05" outer diameter ). We also include a 1.05 Top Distributor Twist On - part # MD1203 at no charge.
