I don't agree that this should be pumped into the Sound or an open field. These can be critical and fragile environments. This is not a heavily populated area and the ecosystems here may not handle the influence like this. In other areas of the country, the ecosystems near land have already adapted to the overflow of man. I am not a huge tree-hugger but I do understand that my actions have influences on those around me.
I am talking about doing this into a landscaped area where you could drown a begonia or some lawn and let the chemicals degrade on your property before before they flow off you land and become someone (everyone) else's problems.
I just read the other message. A siphon can be started by putting the one of the hose in the pool and filling the hose from the spigot into the pool. You then turn off the spigot and then remove the hose from the bib, the siphon will draw the water to that end of the hose and start drawing water out of the pool.
Another way is to place the entire hose in the pool, remove all air in the hose and then plg the end and pull it ove the side of the pool and then remove the plug, the Water will flow out of the pool, via the hose.
These methods will draw all but a few inches of water out of the pool.
