An article posted 24 July asked if anyone knew of another company that makes seastrainer/flushing tops since thoroflush closed their doors. Does anyone know? Someone recently mentioned that there is a device (like a toilet plunger) that is placed over your hull fitting from the outside, and has two hose connections on a "Y" valve. One goes to the freshwater, and the other to a bucket of AF. Has anyone heard/used this system, and where can you purchase one?
