PLUMBING — To make install easier and to can - serve adhesive, all measuring, tting, and tapering should be done first. Then proceed with the bonding op- eration. To make sure measurements are right, assemble the entire piping system "dry" (without adhesive) before bonding. Where accuracy is important, "dry" assembly is a must. For close tolerance piping refer to A. O. Smith - Inland Installation Manual No. 9474. FLEXIBLE HOSE CONNECTIONS — Flexible hose con- nections can be installed in product and vent lines at the point where they leave the tank. On suction pump installa- tion they can be put in just before the pump riser. Use of flexible connections can prevent breaking of lines or fit- tings where settlement might cause tank movement, or where expansion and contraction might cause movemen4 of the pipe. The drawings of typical island piping indicate how con- nections can be made using standard RED THREAD R adapters. 14i RED THREAD II pipe is inherently flexible. API Publication 1615 states: "Fiberglass piping, which is inherently flexible, does not require swing joints, if at least 4 feet of straight run is provided between any directional change exceeding 30*." BURIAL — Minimum acceptable burial depths are given in this section. In some cases greatest depths may be required by the authority having jurisdiction or by local codes. The maximum allowable burial depth is 24 feet for burial in moderately compacted soils which do not contain clay and where the soil modulus is at least 1000 psi. Minimum burial depths shown in the above burial table are acceptable if, and only if, the ditch width is 2.5 feet or less; the paved surfaces extend at least 2 feet on either side of the ditch; the fill material is clean sand or 1/s" to 3/4" pea gravel and 6" of the fill material is placed under the pipe as bedding material. Remaining backfill above Sand or Pea Gravel amounts as shown in the last column of the burial table can be native soil if desired. If burial conditions other than those discussed above exist, contact A. O. Smith -Inland Inc. REPAIRING — On rare occasions it may be necessary to repair a damaged section of RED THREAD II pipe. Where damage is in the form of a puncture, the pipe can be repaired using a patch made from the pipe itself. If a considerable length of pipe is involved, it is best to re- place it with a new section of pipe. Complete information for making repairs are included in the A. O. Smith -Inland Inc. Installation Instructions Manual No. 1055. It is the policy of A. O Smith -Inland Inc. to improve its products continually.
