What would be a good option to pump out hot dunder from the bottom of the electric boiler after a run? There is a side drain near the bottom but it leaves about 5 litres in the bottom of the boiler and I would like to get the rest out before I add more wash for the next run.
I will look at getting a bottom drain added in the future but need a solution for now.
There is a 4" fill port so I thought about adding cold water to the dunder to cool it down and using the shop vac to suck the remaining out.
Anyone have any suggestions?
