So I've got a Warped Sportz Z-force pump. When I air it up after cocking it, a profuse leak comes from the barrel/breach. After doing some research, I have found that this happens because of either a bad cup seal, valve or valve o-rings. I tried to swap the valve o-rings, I sanded the cup seal with fine grit sand paper, turned up the input pressure, and backed out the ivg, but nothing has worked.
SO I am going to try and get an entirely new valve and cup seal. I have heard good things about the maddman rocket valves and pb gateway has trilogy/SR valves and cup seals for around the same price. What should I do? Are there other 11/16 valves out there that will work?
Thanks for the help!!
I have my sidewinder unscrewed almost all the way and the leak persists. I got a palmers 11/16 valve, red spyder velocity spring in place of my valve spring and a green madman spring. Any other tips on stopping this leak?
Try a more petroleum compound lube like dow 55 on your valve orings. I have seen older markers get grooves worn in where the valve orings are. I have used fatter orings and dow55 with varying results. Good luck.
