you need sand from Bondi Beach ( Australia ) as upside down sand is the only type of sand that will stop anti-clockwise EMF causing premature escape of the electricity in the secondary, because the secondary is centre tapped to northern hemisphere earth.I was given a couple of 3 kva site transformers, both have broken bases and all the sand has leaked out, epoxying a new base on is no problem, and I will only be using them myself at home, but what kind of sand should I refill them with ?
Isn’t that builder’s sand?Block paving joint filling sand, it's dry and fine.
Whether it's fine to refill a damaged TX is another thing.

Make them heavy.Not sure why the'd be sand filled in the first place?
