Turbulator Kit 1040020 used with some Autotrol Valves.
MD7133 935T Turbo Distributor is what our KIT is called, and can be used with Fleck, Autotrol, and Clack Valves made since 1997.
Bottom screen Slot size .010-.013
Includes 3 ft. of 13/16" pipe
and instructions to construct to fit your size tank,
and a Top Distributor ( MD1203 )
instead of the "old style" Deflector Cone in picture.
Small section of 13/16" pipe is included for the backwash tube. This tube must be cut a length 7" shorter than the resin bed depth, so you don't need a long piece. The main distributor tube can be made with 3/4" PVC pipe.
If your Valve uses a 13/16" opening, then you can insert a small section of the 13/16" pipe into the center of the 3/4" PVC Sch 40 pipe.
NOTE: While PVC cement can be used to assembly the parts, the manufacturer recommends using MEK ( Methyl Ethyl Ketone ), sometimes called Butanone, which can be usually be found near the Turpentine section of large hardware stores.
NOTE: It is recommended to increase the Control Valve's backwash flow control rate by 30% when using a Turbulator.Can only be used with RESIN ( not Birm, Carbon, Greensand, Calcite, Gravel, etc ).. just water softener RESIN
