I've been servicing my Apeks DS4 first stages for a while with no problems.
I bought a used one just to have around as a spare and because the deal was good. I recently O2 cleaned and serviced it. Here's my question:
IP locks up reliably but then creeps up about 10 psi and then stays there. This 10 psi creep takes about minute. It stops there and holds indefinitely. It happens wherever I set the IP - if I start at 125, it will go to 135. If I start at 135, it will go to 145. Purge the regulator and it will start over again - lock at 125 and slowly creep up to 135 and stay there, or 135-145, or whatever.
If it was 2-3 psi, that would not be a concern, but 10 seems excessive. My other DS4s do not do this.
Any thoughts as to why, whether it matters, and if so, the fix?
Many thanks.
