From pot still to reflux still -temperature problem

[St Plugger]

Jedstar, I can see that water temp may be a problem but as I live on a rural property I can use the rainwater tanks, though I'll probably need to source some food grade hose combined with 3/4" poly for that exercise!

the cooling water won't be in contact with your product, so food grade would be unnecessary imho.
pump it through the still condensors and back to the tanks.
