In the mean time, I have recieved the "Zerich Pressure Blaster" and made a couple absolvers for it to shoot 3 or 5 darts. It has a pressure relief valve, but I have not yet reached that pressure. I used gorilla glue to mount a male 1/2" pvc fitting to the drain blaster because that fits some other pieces I already made for a Titan. For the absolver I used a Spectre cylinder and a 2" x 1/2" pvc bushing.
