Product Information

The RVI Test Port system is designed for pressure field extension testing and soil gas sampling. It allows for easy installation and sampling of radon levels in concrete floors.

Equipment Required:

• RVI Test Port
• Cap
• Tool

Chemical Compatibility:
Refer to the Polyethylene Chemical Compatibility Chart for a partial list of compatible chemicals.

Product Usage Instructions

Installation Procedure:

1. Check for buried obstacles (pipes, electrical lines, etc.) prior to drilling a hole in the concrete floor.
2. Drill a hole in the concrete floor using the appropriate tool.
3. Remove the drill bit and clean the hole and surrounding concrete surface using a vacuum.
4. Apply RadonAway Pro Sealant around the RVI Test Port at a point near the center of the ribbed section.
5. Insert the lower end of the Port into the drilled hole.
6. Use the Port Installation/Cap Removal Tool to push the Port flush with the floor.
7. Wipe off any excess caulk from around the Port or on the tool.
8. Place the RVI Cap on the Port when not in use.

Cap Removal / Re-installation Procedure:

1. Insert the + end of the Tool into the Cap and twist from side to side to loosen it.
2. Slide the wedge side of the Tool between the Cap and the concrete floor and slowly pry the Cap free from the Port.
3. Ensure the Cap is free of dirt and debris before re-installing.

Testing / Sampling Procedure:

1. Connect tubing to the Port for testing or sampling.
2. Disconnect tubing from the Port after completing the test or sampling.
3. Re-install the Cap on the Port.

Port Hole Abandonment and Closure:
If the Port was installed as a temporary testing location, it can be abandoned by pushing it further into the drill hole using a 3/16 flathead screwdriver and hammer.

OVERVIEW

The RadonAway Radon and Vapor Intrusion (RVI) Test Port is designed to be a low-cost, quick and easy way to conduct sub-slab differential pressure measurements and soil gas sampling beneath a concrete slab. The system consists of three components; a Port, Port Cap and a Port Installation/Cap Removal Tool which can be installed as a temporary or permanent sample point. This product is made from durable polyethylene plastic and has been designed to stand up to typical building traffic. Note: Check RVI Test Port’s chemical compatibility with the known or suspected chemical(s) present at your project site (refer to Page 4 for a partial Chemical Resistance Chart).
This instruction describes the installation and usage of the RVI Test Port system for use in pressure field extension testing and soil gas sampling.

EQUIPMENT REQUIRED

• RVI Test Port
• RVI Cap
• RVI Installation/Cap Removal Tool
• Rotary Hammer Drill
• ½” Diameter Hammer Bit
• Wet/Dry Vacuum with HEPA Filter (recommended)
• Radon Pro PGS Sealant
• ¼” Screwdriver (if closing out the port location)
• Lightweight Hammer (if closing out the port location – See Port Hole Closure Section)
• Hole patching material (hydraulic cement or RadonAway Pro Sealant and a putty knife or trowel (for repairing the hole if the RVI Test Drill Hole)

INSTALLATION PROCEDURE

1. Check for buried obstacles (pipes, electrical lines, etc.) prior to drilling hole in concrete floor.

2. Set up wet/dry vacuum to collect drill debris and dust. Drill a ½” (13mm) diameter hole completely through the concrete slab into the sub base material. The hole must be ½” (13mm) in diameter to ensure a seal around the RVI Test Port (Photo 1).

3. Remove the drill bit, and remove the loose debris and dust from the hole and surrounding concrete surface using the vacuum.

4. Place a bead of RadonAway Pro Sealant around the RVI Test Port (Port) at a point near the center of the ribbed section of the port (Photo 2).

5. Place the lower end of the Port into the drilled hole. Using the side of the Port Installation/Cap Removal Tool (Tool) that has the flat surface with the protruding pin (Photo 3) into the top (large) end of the Port so that the tool’s flat surface is flush with the top edge of the Port (Photo 4).
   

6. Push the tool to the floor until the tool and Port is flush with floor (Photo 5). Make sure the Tool is aligned parallel to the Port to avoid damaging the port. If port cannot be pushed flush to the floor by hand, use a hammer to tap the top flat part of tool. Wipe up any excess visible caulk from around port or on the tool.

7. Place the RVI Cap (Cap) on the Port while not being used for sub-slab differential pressure measurements or soil gas sampling (Photo 6).

CAP REMOVAL / RE-INSTALLATION PROCEDURE

1. Using the “+” side of the Tool (Photo 7), insert the “+” end into the Cap and twist from side to side several times to make sure that the Cap is loose for subsequent removal (Photo 8).
   

2. Using the “wedge” side of the Tool (Photo 9), slide the wedge between the Cap and the concrete floor and slowly pry moving the Tool around the Cap lip to several locations until the Cap is completely free of the Port (Photo 10).
   

3. Prior to re-installing, make sure Cap is free of dirt and debris in order to ensure that the Cap does not become bound to the Port.

TESTING / SAMPLING PROCEDURE

Remove the Cap using the Tool and push ¼” outside diameter (O.D.) flexible tubing into the open hole at the top of the Port (Photo 11). The tubing should go into the Port approximately ½” or until snug to ensure a proper seal.

• Connect tubing to appropriate testing or sampling devices to be used.
• Upon completion of test / sampling, disconnect tubing from the Port and re-install Cap (Photo 12).

PORT HOLE ABANDONMENT AND CLOSURE

If the port has been installed as a temporary testing location, the port may be abandoned by pushing the port further into the drill hole a minimum of 2” using a 3/16” flathead screwdriver and hammer.
To complete abandonment – fill the ½” drill hole with a hole patching material (e.g., hydraulic cement or RadonAway Pro Sealant until flush with the surrounding surface elevation.) Use a putty knife or trowel to smooth the surface.

*Ratings of chemical behavior listed in this chart apply at a 48‐hr exposure period. These recommendations are based upon information from material suppliers and careful examination of available published information and are believed to be accurate. However, since the resistance of plastics can be affected by concentration, temperature, presence of other chemicals and other factors. This information should be considered as a general guide rather than an unqualified guarantee. Ultimately, the customer must determine the suitability of the product material of construction used in various solutions.
