Bought 2 new apeks dts. Other one seems to leak a bit, only seen when opening valve and closing it. Takes about 1 min to leak 10 bars. Changed pressure meters, 2nd stages, but still leaks. Also IP creeps from 8-> over 10 bars in 2-3minutes if just left alone. When submerged hard to see small bubbles near turret coming out. So I got lemon? Should I try to fix it myself (I got the equipment) or send back (different country I bought from)
