I don't know what waterCost is, nor can I figure what good multiplying it by 32 will achieve.

You're left-shifting a float variable?
A float variable read from a Hall Effect sensor?
I don't get it.

bakxr:
I know my code doesn't work as of yet, I believe the comparison was < 5.00> However I was actually more concerned about the rest of the formatting in that if statement.

What are your concerns, specifically?

A well-written while loop inside an "if" is just the same as a while loop anywhere else, and probably as unwelcome and unnecessary.

The loop() function loops, and that is why while loops are often unwelcome and unnecessary.

Your while loop is not well-written.
