Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

Since our founding in 2003, we've become the largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Rocket Launcher Material

Post by PETrockets » Wed Jul 22, 2015 11:08 pm

Hello everyone, I've been doing water rockets for 3 years and every launcher I've constructed has been made out hydraulic PVC pipes (the only thing I could afford at the time) and they worked amazingly until yesterday when one of them exploded at 120 PSI (I usually use 200-250 PSI) now I'm afraid of using the rest of my launchers. So the question is: any other material I could use for my launchers? I've seen this CPVC pipes but I don't know if they'll work.
Any help is appreciated

At those pressures, you should switch to steel pipe.

PVC capability varies with age and temp.
