I inherited a 18'x36' pool when we bought our house a few years ago. The deep end is about 8 feet wit sloped sides. One thing I noticed is that the bottom drain does not seem to draw water through it, at least I can't feel it and I tried putting something by it to see if it was draw toward it and it doesn't seem to be working.
Someone indicated to me that the previous owner probably blocked it on purpose because they were afraid of their kids being sucked to the bottom by it and drowning. Does this seem plausible to anyone? Should I unblock it? Without it, the only return I have is the skimmer basket? Since this is near the surface does that provide enough to filter and clean the pool effectively?
