I hope this one works better than the one you have. I don't think you are going to get one of these to leak by having too much pressure. If it can handle the water pressure going in your house, it should handle a little maxijet. You should have no problems using the pump the way you have it on this one.

Thanks ... hope you have fun putting yours together.
Make sure you both try to post pics of your reactors when you are done.
