- AWWA C605 - Underground Installation of Polyvinyl Chloride (PVC) Pressure Pipe and Fittings for Water
- ASTM D 1784 - Standard Specification for Rigid Poly (Vinyl Chloride) (PVC) Compounds and Chlorinated Poly (Vinyl Chloride) (CPVC) Compounds
- ASTM D 3139 - Standard Specification for Joints
for Plastic Pressure Pipes Using Flexible Elastomeric Seals
- ASTM F 477 - Standard Specification for
Elastomeric Seals (Gaskets) for Joining Plastic Pipe
- ASTM D 2122 - Standard Method of Determining
Dimensions of Thermoplastic Pipe and Fittings
- ASTM D 2837 - Method for Obtaining Hydrostatic
Design Basis for Thermoplastic Pipe Materials
The pipe shall be extruded from compounds meeting (PVC1120) the requirements of Cell Classification 12454-B, as defined in ASTM D 1784, Standard Specification for Rigid Poly (Vinyl Chloride) (PVC) Compounds and Chlorinated Poly (Vinyl Chloride) (CPVC) Compounds. The PVC shall also be listed by the National Sanitation Foundation (NSF) for use in potable water.
Vinyltech pipe shall be manufactured in accordance with AWWA C905-97.
The gasket shall be reinforced with a steel band and meet the requirements of ASTM F477. Vinyltech pipe shall have an integral bell end with a locked-in factory installed gasket and shall meet the joint requirements of ASTM D 3139.
The pipe shall be marked in accordance with AWWA C905 as in the following example.
- Manufacturer’s name and production codes
- Nominal size, dimension ratio number, and O.D. base (for example, 16” DR 18 CI)
- Materials cell classification (PVC1120)
- AWWA pressure rating (PR 165, or PR 235) and hydrostatic test pressure (T/330, or T/470)
- AWWA designation number (AWWA C905)
- Production date code (VOO 101A)
- Seal of the testing agency that verified the suitability of the pipe and the material for potable water (NSF)

Each length of the pipe including the bell shall be hydrostatically tested in accordance with AWWA C905-97. The pipe shall meet all additional test requirements as described in AWWA C905. Our full time quality assurance staff continually administers a rigid program of tests to maintain the production of the best pipe products available.
Recommended installation procedure of Vinyltech Corporation and the Uni-Bell PVC Pipe Association are outlined in AWWA C605, Underground Installation of Polyvinyl Chloride (PVC) Pressure Pipe and Fittings for Water. The uni-
Bell Handbook of PVC Pipe is also an invaluable resource guide for design and installation.
The consistent success of tapping PVC pressure pipe is contingent upon the use of proper procedures and equipment. Tapping should be as recommended in AWWA C605.
Assembly of Vinyltech PVC transmission pipe is easily accomplished. A depth of entry mark is on each spigot end to serve as a visual check for rapid, accurate joint inspection. Do not over insert.
- Remove any mud, sand, or other foreign
matter from the belled and spigot ends of the
pipe. Carefully clean the gasket area.
- With a clean applicator (a brush or hand)
lubricate the entire surface of the pipe from
the spigot end to the depth of entry mark and
the contact surface of the gasket with
Vinyltech Brand Lubricant.
- Brace the bell to avoid disturbing the already
installed joints. Align the pipe, insert the
spigot into the bell and push until the entry
mark is reached. Do not insert past the
entry mark line.
