Key Features:

VAC-A-TEE is a trenchless cleanout installation system that is environmentally friendly, utility friendly and installer friendly. Installed by means of hydro or vacuum excavation, the VAC-A-TEE system is a clean and safe method for installing a new cleanout. The cleanout provides access to the sewer lateral pipe for cleaning, lining, root removal, CCTV, etc. The system involves a patented PVC saddle, riser pipe of appropriate length and proprietary hybrid adhesive/sealant. After a small diameter borehole has been created, the contractor applies the adhesive to the underside of the saddle and then snaps it onto the lateral pipe. Once the adhesive cures, it forms a water-tight seal with the pipe. A diamond core saw is then used to cut and remove the crown of the pipe. Finally, the borehole is backfilled and sod is used to restore the landscaping, leaving the yard virtually untouched.

ASTM F3097

Standard Practice for Installation of an Outside Sewer Service Cleanout through a Minimally Invasive Small Bore Vacuum Excavation

Significance and Use

Purchase the full version of this standard by visiting the ASTM website here.

This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of sewer service laterals and its connection to the main through the use of a resin-impregnated tube installed within an existing sewer lateral. As for any practice, modifications may be required for specific job conditions.

1. Scope

  1. This practice covers installation methods, test methods and required materials for the installation of an outside sewer service clean out, by means of a small vacuum excavated borehole. The utilization of this practice greatly reduces disruption to the general public and requires minimal restoration.
  2. Units-the values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
  3. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
