I went to add chlorine to my in line chlorinator and also opened the air relief at the same time. Upon returning to the pad from getting the chlorine, i glanced at the pool and saw DE oozing out of the main drains. The pump basket was also full of it and gurgling like crazy.
I swear i had opened the air relief before but I think that was a bad idea. Not even sure why i did it, but thought that is what i always did. So should i leave air relief closed with chlorinator opened up?
