well guys, the opportunity came today what i had been waiting for, heavy rain, thanks to (Lewis doubtfires Email to me about collecting rain water)
i did 2 test one after the other, collected from inside, and outside, OK so here's what happen, outside, i left a clean bucket to catch the rain as it fell, the rain was so heavy it filled within an hour, by inside i mean in my shed?? you may ask yourselves, to explain, my shed is a flat roof 15 by 12 wide. a lot of rain sits on it, i drilled a hole in the center of the shed,
place a plastic water funnel underneath the hole, i put a tube on the outlet of the funnel and directed it to a 25ltr container, ok will come back to explain this part later. back to lewis doubfires email, lewis told me he done the test, himself outside was 15ppm, but he went on to explain the rain that came from his shed was only 7ppm, and he was puzzled as to why this was happening, so back to my shed, as above, collected a full container of the rain water from the shed roof, now bearing in mind i used no filters or resin, the reading from my shed was 1ppm :?: incredible,but outside reading was 11ppm, now back to lewis email, he told me the he thinks it could be some kind of effect from the roofing felt,
i did the test twice, with exactly the same readings, lewis i think we are on to something here, if i wanted i could put some kind of filter and resin
in the funnel, and i am very confident, it would come out 000ppm.
my roofing felt is bitumen roofing felt,
