Re: GROCO K-type marine head question
Sounds like inlet is leaking even when closed and showing your waterline level in the bowl. Can't trust the dry bowl lever either as easy for flapper to seep there too .Don't worry if you are getting a calcium buildup it will soon smell .Removing calcium crystal from hoses and rubber parts is just part of messing with boats ( Once had a bowl level with water line and surprised me every morning. Solved it by adding a Uvent up a bulkhead .Tiny sucking air vent still allowed good flush )
