I have an old (1984) electric flush head a holding tank. When we flush it, everything goes down, but when we release the flush button, some paper and water comes back up into the toilet...sometimes more than just paper and water. Also, the water coming back into or refilling the toilet is clear. Shouldn't it be the blue treated water? Do I just add the blue holding tank chemicals through the toilet or down into the waste cap on the deck?
Thanks in advance...
