1、Designation: F 481 97 (Reapproved 2002)An American National StandardStandard Practice forInstallation of Thermoplastic Pipe and Corrugated Pipe inSeptic Tank Leach Fields1This standard is issued under the fixed designation F 481; the number immediately following the designation indicates the year of
2、original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes procedures for handling andinstall
3、ing thermoplastic pipe and corrugated pipe in septic tankleach fields, curtain drains, and from the septic tank to the leachfield. Proper installation ensures that the pipe will satisfactorilyconvey and distribute partially treated waste water to aleaching field for additional treatment and disposal

The curtain or perimeter drain will function toprotect the soil absorption capacity of the leach field.1.2 To ensure compliance with local regulatory provisions,the local approving authority (local health departments and soforth) should be contacted regarding specific requirement

6、.1.3.2 Perforated, for use in leach field or curtain drain:Specifications D 2729, D 2751, F 405, F 810, F 891, andF 892.1.4 Pipe intended for installation in accordance with thispractice should have a minimum pipe stiffness as specified inthe appropriate product standard referenced in 1.3.1 or 1.3.2
7、.1.5 The values stated in inch-pound units are to be regardedas the standard.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

General Requirements4.1 StoragePipe should be stored with support from a flatsurface to prevent the pipe from developing a permanent set.4.2 HandlingCare should be exercised during loading,unloading,
17、 and in transit because pipe may be damaged byabrasion and sharp edges. Because thermoplastics are tempo-rarily softened by high temperatures, care should be takenunder these conditions to avoid damage during handlingoperations.4.3 If contact with chemicals not ordinarily present insanitary sewage i
18、s anticipated, the approval of the regulatoryauthority to install pipe should be obtained.NOTE 1The manufacturer should be contacted for information onchemical resistance.4.4 Coiled pipe is not recommended for use in leach fieldsbecause it is difficult to install at the proper grade andalignment; it
19、 is acceptable with special equipment installation.NOTE 2Corrugated interior pipe should not be used between thedwelling and the waste water treatment unit (septic tank or similar device)because the corrugations may inhibit the flow of solids contained in thewaste.5. InstallationLeach Field5.1 Leach
20、 fields should be constructed to meet the require-ments of the local Department of Health or other governingauthority, which should be contacted for information andrequirements on design, location, installation, materials, and soforth.5.2 Before installation, pipe should be inspected for damagesuch
21、as kinks, crushed portions, splits, and so forth. Anydamaged portions of pipe shall be cut out as a cylinder anddiscarded. Make a visual check of the bore to ensure it is clearof foreign objects that might impede flow.5.3 Gravel SystemsFor proper waste water flow into thesurrounding soils and to pro
