My old Rule aerator pump was attached to the Flow Rite V# livewell valve (3/4" NPT) with some kind of white sealant (adhesive)? I've put a fair bit of torque on them trying to separate them, to no avail. I don't know whether the white material is just sealant or a sealant+adhesive (e.g. 3M 4200 or 5200). I'm about ready to just force it, but before I do - any tips for getting these two apart?
Thanks!
