1 Installing Drainage SystemsProper installation of Orion Drainage sys-tems is extremely important in assuring thatinstallations perform flawlessly for years. Supporting a Drainage SystemSince Polypropylene has a higher expan-sion rate than that of other materials, it cannotbe anchored to restrict movement from ther-mal expansion incurred from chemical reac-tions or the inadvertent dumping of hot waterinto the acid waste recommends the use of clevis orloop type pipe hangers. If split-ring or otherhanger types are used the hanger should bea size larger than the pipe being supportedso the polypropylene pipe is free to move.

2 (For example, if supporting 2" pipe, use 3"hangers, or when supporting 3" pipe, use4" hangers, etc.)Warnings: The use of uni-strut type hangers or anyhanger which relies on clamp tightness forsupport voids manufacturers warranty. Do not clamp a polypropylene pipe sys-tem tightly. It must be free to move.

Underground Installation of Orion Acid Waste SystemsThe trench as excavated for the pipe installationmust be free of loose stones, building materials oroutcroppings, and must provide minimum clear-ance around pipe of half the pipe diameter oneach side (horizontally) and one pipe diameterabove and below (vertically). The trench shall bebackfilled over the unexcavated base to a depth ofone pipe diameter with clean backfill. The backfillmaterial shall be free of stones and foreign matterand shall be capable of passing a No.

When theselected backfill meets a depth of one diameterover the pipe, then backfilling can proceed withnormal fill until complete. Fill shall be compact-ed using hand held compacting equipmentwhen fill is midway up the pipe, and again whenthe fill is over one diameter over the compacting equipment can beused after the initial backfill is ProceduresFully inspect the installed piping for evidenceof mechanical abuse and suspect the system into convenient test sections,not exceeding 1000 ft.

7 The piping should becapped off with an expandable plug at the endof the pipesection to be suggest that straight lengths of pipeshould be backfilled between the fittingsbeing tested, prior to fill the pipe section with water, takingcare to remove all trapped air in the air release valves in any high spots inthe system . Do not pressurize at this the pipe for at least one hour, to allowan equilibrium temperature to be check the system for leaks. If clear,check for and remove any remaining air fromthe the system to a suggested maxi-mum of 10 feet head by means of a standard10 foot standing water test using a 10-footvertical riser, or a low pressure hand the line at 10 feet of head pressure fora period of up to 8 hours, during which timethe water level should not change, (standingwater test) or the pressure gauge readingshould not change (hand pump test).

Inthis event, inspect for joint leaks.)))

Dry or marginal Rionfusejoints can be easily re-fused by following the proceduresdetailed in this catalog. Leaking joints can be backweldedif necessary. It should not be necessary to cut out joints,unless the joint haspreviously been overheated, contaminated, fractured orvery badly made in the first place. Where joints have tobe cut out and replaced, the procedures for field cuts andjoint installation detailed in this manual should be the 10 feet head test after repairing any leaking joints, following the procedure described : Tanks should not be pressure :This system was designed for acid waste of a gravitynature.
