The sort of things you used to see on paraffin heaters with separate tanks .
Do they make these to fit 5 gallon containers ... or do I have to make and design one myself.
This is so that I can invert a standard five gallon container full of waste engine oil ....and have it slowly empty completly............but only pour out when the oil in a reservoir below lowers.
This is the next stage in the design of my waste oil central heating system.
Like a budgie water feeder ...but with a self sealing action when lifted out of the reservoir.
Or for you drinkers ......works like an optic dispensor...but without the 1/6 of a gill function. if they are out there, anyone got one ...preferably made of metal.
Rubber seals can soon be replaced with something more up to the job.
now has Swirled Air System ...SAS :)all the best.mark
