What is the easiest and quickest way to siphon water from a wading pool with a garden hose without use of a pump?

If you have a low spot that you could put the end of a hose, than you could hook a hose to the other end and feed it water to get the flow started. After getting the water running, hold the connected ends under the water in the pool and take them apart. Keep the end from the hose going to the low spot under the water. Have something handy to put on the end in the pool to hold it down to the bottom. If there is no are leaks in the hose and you keep the end under water, it should mostly drain the pool.

The discharge end of the hose must be lower than the intake end. When the level of water in the pool falls to the same level as the discharge end, the siphon will stop flowing. To drain a pool completely, the discharge end must be lower than the lowest spot in the pool and the intake end must be place at that spot. To start the siphon you can immerse the hose completely in water to get all the air out, plug the discharge end of the hose with your thumb or a suitable cap as you drag it over the side of the pool, and uncap it when the discharge end is at a low point. This method of starting a siphon avoids sucking or inhaling on the hose end, with the attendant risk of aspirating contaminated water into one's lungs.
