>>649073>get a 5 gallon jug (or two) refill as neededYes - this works.
But don't get round "jugs" ; get like "jerry" can shaped water drums , the flat profile makes them easier to lift and carry because the CG is closer to your body [also available in smaller sizes], make sure it comes with a Tap ; and many are now 'wide-mouth' so that makes them easier to fill. [you may want to consider a short hose and connectors/adaptors as needed]]
