5 gal is pretty normal.
a plastic 5 jug is the norm from what I've seen on many TMs
don't know if there's a "technical" name for it.
Guess whatever the manufacture calls it in the manual would be the "correct' term...at least for that manufacture .
Steamway calls it a "solution tank"
I've always called it the "emulsion tank"
You can call it the 'soap jug" if you want .
I was going to say "stock-pile jugs"
You can get them at the Win-co stores here in Idaho for about 5 bucks. Or you can go to the carpet cleaning supply house and pay $12.
ya'll could just buy 5 gal of juice from DSC (they have many very good products) and you'll have a 5 gal jug .
I've given away dozens of them over the years .
Headpack is the name from the manufacturers. Solution jug works OK as well. $11 from Interlink. We get them from Winco for $5.95 but then we wash them out for you. Plus we have to make a profit.
