Our Water Rocket Launcher won't read accurate PSI. The water is getting pressurized, and it shoots up, but the PSI reader registers 0 the whole time. Are the coaches missing a step, or could it need to be replaced? How often should we replace our gauge or launcher?
Probably best to buy a new pump with integrated pressure gauge. You
should be able to get reimbursed with reciept. I suggest one with a
bit larger piston to fill the rocket faster. They cost about $30 on
Sorry if this answer has misled anyone. The school team is responsible for the upkeep on the equipment at this time and the WESO board would not be reimbursing this expense.
