The spider gasket inside the 6-position valve is probably leaking. Take the model number of the valve to a local pool store and they can order a replacement. You will also need a special sealant to install the new gasket.

Do not drain a vinyl liner pool mor than half way....ever... If you have a fiberglass, or gunite pool it is important to pull the hydrostatic plug under the main drain cover. If you live down a hill, or where there is a high water table, the water pressure underground can lift the empty pool out of the ground (more common in fiberglass pools). If you have a sand or DE filter switch the valve to waste. make sure that you have the skimmer turned off, and the pump is only sucking from the pool main drain (spa drain closed also), and turn the pump on. Make sure the waste hose is far enough away so you dont add any hydrostatic pressure.

You need a rebuild kit for the valve and possible a sand change. Sand should be changed ever 3 - 5 years or so depending on overall pool conditions.
The gasket inside the valve is out of place and therefore allowing water to leak out the waste port. Use a gokit to replace all the gasket/orings and you should stop the leak.
If the flow is still bad, inspect the sand and change it if necessary.

It will not be glued, it is just stuck in there good. You will need to scrape, pull, twist or otherwise convince it to come out as best you can and then clean the area well before installing the new one.

The model number you give is for the multi port valve. Did you need the valve manual or the filter manual? Go to haywardnet.com for their full line and manuals. Here is the link for the SP0714 valve at their site. It is in PDF format...
