To permit easy removal for sump pump servicing, the cover shall be sealed using silicone or other non-permanent type caulking materials or an air-tight gasket. 15.8 Penetrations of sump covers to accommodate electrical wiring, water ejection pipes, Radon Testing or radon vent pipes shall be designed to permit air-tight sealing around penetrations, using caulk or grommets. 

Sump covers that permit observation of conditions in the sump pit are recommended. Plastic sheeting installed in crawlspaces as soil-gas retarders shall be a minimum of 6 mil (3 mil cross-laminated) polyethylene or equivalent flexible material. Heavier gauge sheeting should be used when crawlspaces are used for storage, Radon Testing or frequent entry is required for maintenance of utilities. 

Any wood used in attaching soil-gas retarder membranes to crawlspace walls or Radon Testing piers shall be pressure treated or naturally resistant to decay and termites. 16.0 MONITORS AND LABELING 16.1 All active soil depressurization and block wall depressurization radon mitigation systems shall include a mechanism to monitor system performance and warn of system failure. 

The mechanism shall be simple to read or interpret and be located where it is easily seen or heard by building occupants and protected from damage or Radon Testing destruction. Electrical radon mitigation system monitors (whether visual or audible) shall be installed on non-switched circuits and be designed to reset automatically when power is restored after service or power supply failure. Battery operated monitoring devices shall not be used unless they are equipped with a low-power warning feature.
