To complete the installation fit the externally located Easi-Sump Cap-Link to the 110mm PVC-U pipe leading to the sub-floor Easi-Sump radon sump. This pipe should be cut to finish flush with the finished surface of the external wall (see drawings below).
The 101mm recommended dimension, (see drawings above), between the external face of the wall and the central drill location mark on the Easi-Sump Cap-Link cover, facilitates the use of standard pipe fitting for a Radon Vent Pipe (RVP) if one is required at a later date.
The cover of the Easi-Sump Cap-Link is supplied already in position, with stainless steel screws pre-fixed. This is to prevent:
- Tampering and/or unauthorised interference;
- Rain penetration and/or vermin entry into the subfloor network of the building.
There is no need to open these screws when installing the Easi-Sump Cap-Link.
When a Radon Soil Gas Control System is being activated, a circular section of the cover is removed to install a Radon Vent Pipe. This section is of sufficient size to accept a 110mm PVC-U pipe, with a small clearance all around. A central drill locator mark in the cover facilitates removal on site.
