[TheForge] Sand blaster problem: hose blows off

[Jerry Frost]

Depending on how old the hose is it may not be competent enough to stay 
on at pressure. Rubber loses volatiles over time, it's what causes the 
weather checking of old tires. the volatiles are what keep rubber flexible

Just because you can get the hose to stay on at pressure does NOT mean 
it's going to stay on or in one piece.
