I believe the FW strainer for the washdown on my boat is partially clogged. The issue is that I have drawers inserted into the port side seat so I can only see/access the strainer from the front hatch. I can see the back of the clear strainer cap, but when I reach into the seat base and put my hand on it my view is blocked and I'm working blind at that point. Is there anything odd or spring loaded under the cap other than the strainer/filter? Anything that is under pressure and going to fly out? I can get a hand on it an easily turn it, I just don't want to spin it off blindly and have it 'explode' springs, etc into the seat base and create a huge problem retrieving them. I wish I could find a good pic of the strainer so I know better what I'm dealing with. thank you
