I wouldn't have even asked this question on such a cheap filter and you have 50 of them.. Cut it open and post the pics or toss it.Dome end is caved in on one side. On a filter with a dome-end bypass it would go straight in the trash but I’m questioning this one because it appears to be a base-end combo valve.
Then again, it cost $1.35 and I have about 50 of them so maybe I’ll just cut my losses.
