Ethyl alcohol intended for industrial use is usually denatured (rendered unfit to drink), typically with methanol, benzene, or kerosene. Pure ethyl alcohol is a colourless, flammable liquid (boiling point 78.5 Â°C [173.3 Â°F]) with an agreeable ethereal odour and a burning taste.
1 Don't try to service your own well. 2  Preventive maintenance is less costly in the long run. 3  Do some homework before getting your water well system serviced.  Take some simple ongoing steps to maintain your well.
Answer: There is no reason to put the hand pump close to the bottom unless it is a shallow well to begin with where you have limited space. If you can, maintain the 20' below static water level. If you are unable to do that then try to get as much cover as you can get over the pump. The pump will operate in as little water as 2'. The reason for the 20' below the water recommendation is to give a reasonable area for water recovery as you pump.
