Okay thank youOn the pump pressure side. 1/4 turn bib, blue handle.
Hook a hose to it, turn on the pump. You will get some water out that way. But go get a sump pump.
ThisMy overflow is nothing more than a 3/4 to one inch pipe on the sidewall, just underneath the coping. It will allow the water to get pretty high before it begins to drain. Look for a pipe, or some type of a grate on the tile just underneath the coping.
