DIY electric Keg , the drain, side or bottom ?

[planohog]

I wanted to state that the best safety minded feature on the keg is the bottom drain and a pump. Using a bucket to move boiling or near boiling water is not a good plan. One trip to emergency room will cost you much much more than the price of the parts and pump.
Its a treat to pump all that away in just a few minutes. Then clean out , and pump that out too. no fuss no muss.
