pR 1FFlg'to SYSTEM INSTALLATION I. INSTALLATION GUIDELINES All Geoflow drip systems require: 100 micron / 150 mesh filter Filter flush valve Field flush valve and Air vent in each zone All Wasteflow Classic drip systems require pressure regulation Handle your dripline and components with care. ROOTGUARD 0 is temperature sensitive. To assure a long life store the drip line out of direct sunlight in a cool place. This should be a consideration when installing the system in very hot and sunny areas. Your system life span will be increased extremes. if it is buried an extra two or three inches below the soil surface, to avoid the warm temperature a) All dripfield construction shall be done in accordance with Local rules and regulations. b) No utilities, cable wire, drain tile, etc shall be located in dripfield. c) Fence off entire dripfield prior to any construction. d) System is not to be installed when ground is wet or frozen. C) Divert all downspouts and surface waters away from dripficid or into curtain drains. f) Excavation, filling and grading should have been finished before installation of the subsurface drip system. g) Be sure you have everything required for the installation before opening trenches. Pre -assemble as many sets of components as practical above ground and in a comfortable place. Compression or Lockslip adapters should be glued to PVC tees, riser units should be pre -assembled, the sub - main manifold with tees can be pre -.assembled and used to mark the beginning and end of WASTEFLOW lines. h) For particularly tough soil conditions moisten the soil the day before opening trenches or installing WASTEFLOW. Remember it is much easier to install the system in moist soil. The soil should be moist but still should allow the proper operation of the installation equipment and not cause smearing in the trenches. The soil surface should be dry so that the installation equipment maintains traction. i) Mark the four comers of the field. The top two comers should be at the same elevation and the bottom two comers should be at a lower elevation. In freezing conditions the bottom dripline must be higher than the supply and return line elevation at the dosing tank. j) Install a watertight dosing tank. In freezing conditions the dosing tank should be at the lowest elevation of the entire system. Install a watertight riser on the dosing tank if necessary. k) Determine the proper size for the supply and return manifolds. See Worksheet line (L). 1) Install the PVC supply line from the dosing tank, up hill through one lower and one upper corner stake of the dispersal field. Please refer to your State guidelines for depth of burial. m) Paint a line between the two remaining corner stakes. 16 Geotlow Design and Installation Manual
