I am not sure if there's an idiomatic way of using the word "drain blaster". I am thinking of several verbs: blasted, unclogged, pushed air into.
However, I am not sure
- "He blasted air with the drain blaster on the toilet"
- "He unclogged the toilet with the drain blaster"
- "He pushed air into the toilet with the drain blaster"
sound very idiomatic.
