Our central Morg oil lubrication system occasionally develops a water bottom in the return tank. We are trying to find an automatic water drain that we can fit to the sump. We have heard of a glass bowl type. Does anyone know where we can get some?

Jamie,
I have used "Esco" BSW drain bottles for this purpose for several different applications. These require an operator to manually activate the spring loaded internal relief valve, ie they were not automatic. I found them on the web as I could not find a local distributor. They have a range of sizes and fittings.
Hope this helps.
