Ok so i know that i can reduce the pressure output of my unit by installing a larger tip. However, when the trigger is closed, that still pumps the system up to full pressure which for me is 4,000 psi. I need all the volume i can get, but i do NOT want to pump the system up to 4,000 psi. I am using a heater which the manufacturer told me had a schedule 40 coil in it and that they would not sell it to run with more than 2000 psi, but said it would take 8,000 before it would burst. He also said 3,000 would probably be alright but 4,000 he would never run through it. My research indicates the heater i am using actually has a schedule 80 coil in it so i don't know if i should believe the info i have found on websites (more than one) that sell this particular unit (Whitco Stinger 2) or if i should believe what the guy at the manufacturer said.
If its a schedule 80 coil it should be fine at 4,000 psi, even a schedule 40 coil is good for 4,000 psi according to this guy but he said he would never recommend it. Said it will leak sooner than normal. Anyways, in light of this i would like to never ever exceed 3,000 psi in the system, i don't think it will ever be necessary. I have a 3500psi relief valve (which doesnt seem to be working, i know ive exceeded 3500psi and it hasnt popped open yet) but the problem with it and most valves i have seen is that they all vent to the atmosphere. I would like it to vent back to the tank so i dont lose any water. I have found this valve: Water Cannon - Pressure Relief Valve MG1000 which looks promising. It appears to have a barbed fitting on it for a hose which i should be able to vent to the tank. Looks just like what the doctor ordered. What do you guys think? Will that valve be able to withstand opening and closing alot like the unloader will ?
