Reply To: Well, I blew it this morning, guys.
Smaug, why did you let the air out of the Marauder?
It’s best to leave air in PCP’s. From what I understand, it’s better for the o-rings, seals, and internal workings to stay under pressure. I’ve also heard that if you drain a metal pressure cylinder all the way it is susceptible to moisture build up due to atmospheric changes causing a negative pressure effect and moist outside air getting in. This has the potential to cause rust on the inside.
If you’re nervous about so much pressure, drain it down to ~100bar.
Edit: Sorry, I just saw that others had posted about this already. Didn’t mean to beat a dead horse!
