Yep it so is
Main line stoppage is a clogged drain line.
no you can not
If its not connected through the skimmer I imagine it's there to empty it. hmmm, on the above. The main drain in pools is for circulating the lower part of the pool and is not intended to drain the pool as in a bath tub.
The pump
Well, if you mean to drain the pool --- it is not a drain as in house plumbing -- the sink -- the tub. It is connected to the skimmer and that is connected to the pump. Your main drain is most likely 'working'. It does not nave to be a strong flow. Well, if you mean to drain the pool --- it is not a drain as in house plumbing -- the sink -- the tub.

Open
Would advise that you get a professional to address the situation first hand. The main drain is intrigal to your circulation.
No. You cannot use the main drain to lower the water level below the skimmer. This is because the main drain is not really a drain. It only connects right back to the 3 port valve in the skimmer.
If you mean you are losing water, it may be a broken or cracked main drain or possibly your hyrdo-static valve is malfunctioning. One other possibility is a break in the pipe going to the main drain.
Water won't drain from shower. Either trap or shower drain line is clogged.
The main line drain is clogged or septic yank needs clean out.
