guys, thanks. I sent PMs, pls. give me a call / email. anyone else as well!
what has to be done is go to the bottom of the deep end and unscrew the grating covers for the main drain. there are 2 small gratings (8" diameter) and each one has 2 screws. then, a plug has to go into each one. it's a rubber stopper with a wingnut that tightens it. then, the covers go back on.
total of 10-15 mins (max) under water. I had the covers off 2 weeks ago when the pool was empty, so I know they come off easily (yes, if I had known this was going to happen I would have done it then!!).
there's no suction down there, but we'll shut off the pool pump at that time just to be sure.
pool is crystal clear (and heated - 83 degrees!).
I have the screwdriver and plugs.
pls. PM if you can help... thank you!!!!!!!!!!!!!!!!!!!!!
