PRO & FLO Stormwater Connections
Vinidex has two systems for making stormwater house connections to StormPRO® and StormFLO® pipes
PRO Grommets for StormFLO® and StormPRO®
- 100mm Grommet -Suit DN225 to DN525
- 150mm Grommet – Suit DN300 to DN900
PRO Saddle for StormPRO® only
- 100mm Saddle – Suit DN225 to DN600
- 150mm Saddle – Suit DN300 to DN600
PROgrommets
The Vinidex PROgrommet range of stormwater service connections provide 100mm and 150mm diameter connections to StormPRO® and StormFLO® pipe up to 900mm nominal diameter.
The following procedure is recommended when installing the PROgrommet:
- Drill hole in pipe using the PROsaw. Hole centre must be located in the valley between corrugations.
- Inspect marking on PROgrommet to ensure the correct size for selected pipe.
- Present PROgrommet to hole with PROgrommet flange to the inside and locating wings to the outside of the pipe.
- Squash the PROgrommet by hand whereby the two locating wings align in the centre.
- With the flattened PROgrommet, form a “C” shape and offer it to the prepared hole.
- Position locating wings in the valley of the pipe profile.
- Apply Vinidex Lubricant to the inside diameter of the PRO stopper. Insert PRO stopper into PROgrommet
- Cut lead-in chamfer on pipe which is to be offered to PRO stopper.
- Mark a line on pipe showing the required insertion depth.
- Dry, degrease and prime the branch pipe spigot and the PRO stopper socket with a lint-free cloth dampened with Vinidex priming fluid.
- Apply a thin even coat of Vinidex Type N solvent cement to the internal surface of the PRO stopper socket first, then apply a heavier, even coat of Vinidex Type N solvent cement up to the witness mark on the branch pipe spigot.
- Insert the branch pipe spigot home to the full depth of the PRO stopper socket
- Hold the joint against movement and rejection of the spigot for a minimum of 30 seconds, then wipe off excess solvent cement from the outside of the joint.
PROsaddles for StormPRO® only
The Vinidex PROsaddle range of stormwater service connections provide 100mm and 150mm diameter connections of the pipe up to 450mm nominal diameter.
The following procedure is recommended when installing PROsaddles:
- Drill a hole in the pipe at the required location as per PROsaw user instructions – pilot drill must be positioned in the valley between corrugations.
- Remove the access cap. Inspect the label on the PROsaddle to ensure the correct size for the selected pipe.
- Apply a thin bead of Butyl Mastic along the raised sealing faces of the gasket and in the holes (top and bottom).
- Place the gasket and saddle in position.
- Secure with the four fasteners provided – do not overtighten.
- Before joining the branch pipe to the saddle, check that the branch pipe has been cut square and all the burrs are removed from the inside and outside edge. Remove all dirt, swarf, and moisture from the branch pipe and the PROsaddle socket.
- Mark the spigot of the branch pipe with a witness mark at a distance equal to the internal depth of the PROsaddle socket.
- Dry, degrease and prime the branch pipe spigot and the PROsaddle socket with a lint-free cloth dampened with Vinidex priming fluid.
- Apply a thin even coat of Vinidex Type N solvent cement to the internal surface of the PROsaddle socket first, then apply a heavier, even coat of Vinidex Type N solvent cement up to the witness mark on the branch pipe spigot.
- Insert the branch pipe spigot home to the full depth of the PRO saddle socket
- Hold the joint against movement and rejection of the spigot for a minimum of 30 seconds, then wipe off excess solvent cement from the outside of the joint.
Embedment material should be placed around the branch pipe and saddle and compacted to a minimum 90% Modified Maximum Dry Density or 60% Density Index, depending on the selected material.
The branch pipe support material should be placed evenly around the pipe and compacted such that relative compaction is consistent with design.
