I’ve been looking through posts and didn’t want to start a new one. I cleaned my filters last week but couldn’t get the drain plug off to spray the sediment out of the bottom of the filter housing. It’s on there pretty tight and I didn’t help by stripping the head of the cap. It’s in a position that doesn’t make it easy to get a good grip on the cap. Any ideas on how to get it off? I’ve bought and new cap and o-ring since I figured I’ll have to replace it after damaging the old one. It’s my understanding that it’s only supposed to be hand tightened.
