BTW...Forest River was bang up on this issue and reached out to ensure I have a fully functional device. I respectfully declined because I do not want another similar device inside and will be just ducky with an external independent filter instead.
In case anyone is interested, the follow-up did include the following warning, this is directly quoted from my FR reply:
"My manager did want me to mention that we do have the FR1 housings tested at a 500psi level before this part goes to our production lines and if the lid is not properly tighten, the housing would perform as it did to you over the weekend. The canister needs to be ratcheted all the way to prevent issues like this from occurring. I myself cannot tighten the lid on the canister alone; it does require some force to secure. "
As I wrote earlier...the torque required to actually open this filter housing was extreme in my opinion (and I am not a weakling....I know about valve torque specs) and when I re-installed the housing with the filter in place, there was NO WAY any additional force could have been applied to tightening it...it was as secure as it possibly could be. I have a feeling the el'cheapo in-line pressure regulator I was using may have let a pressure excursion enter my rig causing the filter housing to pop itself open. I will be searching for a new (better) pressure regulator before my next outing that is for sure!
