Flow director diverter valve tee splits effluent 50/50 or 100% one direction

Four inch flow director splitter valve comes complete with adjustment handle, riser, coupler, and four inch threaded access cap. Special staggered hub fittings on the ‘Versa-tee’ will accommodate PVC or ABS pipe in 4 inch diameter in both Sch40 or thin wall SDR35 sewer drain pipe. Note there is a two inch drop in elevation from inlet pipe (base of tee) to two outlet pipes (top of tee) where the effluent flow splits. Effluent flow can be split 50/50 evenly between the two outlet pipes OR you can alternate the flow 100% to one side or the other. Diverter allows one half of your septic system leachfield to go fallow for a few months to revitalize soil, prevent overloading, and reduce the growth of bio-matting. Three director valves will allow splitting flow between four separate leach field lines. Then you have the option of letting 1/4 of leachfield to go dry seasonally. Flow director splitter valve fitting is designed for gravity flow systems only. Internal weir divides the flow, this is not a gate valve. Not for use in pressurized pipe dosing systems with lift station pump or automatic siphon. Use two gate valves and a tee manifold instead of a director valve with pressurized or siphon effluent systems. We don't sell gate valves given the extremely wide range of quality, features, and size options.

Best practice is to bed valve fitting in at least 6 to 8 inches of 3/4 inch crushed gravel to stabilize and prevent settling during backfill and then ‘wet-set’ atop bagged concrete mix. Distribution boxes and simple tee fittings off-level by as little as 1/8 of an inch will be drastically less than equal 50/50 split. But with director valve, even at 1/8 inch tilt, flow directer delivers relatively equal flows (+/- < 1.3%). Flow diverter distribution valve housing is ABS plastic, so always use multi-purpose cement when attaching to PVC pipe. Prime all joints first, with purple primer, before solvent welding with the multi-purpose cement.
