BIO-TOILET s S SHAPED STEM MODIFIED INSTEAD OF VERTICAL .In the modified S shaped stem the floating yellow colored fecal ( human excreta ) matters are invisible..
But in the present Vertical Stem of the Bio-Toilets the floating yellow colored fecal matters are dancing in the coach which is seriously inauspicious in the early morning time.Please visit the Bio-Toilet and during flushing the floating inauspicious matters are VISIBLE to the naked eyes. I MYSELF EXPERIENCED SERIES OF DRY VOMITING IN MY EMPTY STOMACH IN THE EARLY MORNING IN THE BIO-TOILET AFTER SEEING THE FLOATING INAUSPICIOUS MATTERS.
