An odor extracting system for a toilet bowl of a toilet pedestal, coupleable to a water supply via a flush conduit leading to flush outlets under a rim of the bowl; the bowl being coupleable to a sewage pipe via a U shaped trap; the odor extracting system comprising: an air bypass extending substantially through the pedestal, the air bypass for bypassing the U shaped trap, that is coupled to air intake ports around the toilet bowl, and to the sewage pipe downstream of the U shaped trap; an air pump for pumping air and vapors out of toilet bowl to sewage pipe via the air bypass, and a light weight air valve upstream of the air pump, the air valve to seal the air bypass when said pump is not in use to prevent escape of smells from the sewage pipe to the toilet bowl; said system further comprising a sealing lid coupled to the toilet pedestal, allowing access to the air valve and air pump, whilst preventing escape of odors from the bypass.
