"Rebuilt" my old Groco SVS 1000 seacocks and strainers. Rebuild being cleaning/greasing and new gaskets all around. They appear in good shape but I am having an issue with both of them. they are on the ngine raw water intakes. I break the seal on the top and they fill up, no problem. As I run the water level in the strainer decreases until it is only filled about 1/3. Engine temps are fine but they should be full. Would seem like the only way that could happen is if air is being pulled in somewhere on the unit but....both at same time? I have tightened everything well but still same result. It's an open system so nothing to bleed. Anyone have similar experience? Take them apart and put back together and assume a gasket is out of line in some way on both?
