i could really uae some advice. these will probably seem like dunb questions. i am trying to learn. any help appreciated.
i am pretty new at marine
septic systems. had a lot of boats over years - always subscibed to the less holes in the bottom the better and always just used portapotties. now i have a jabsco head
and it seems to work
ok, although crammed under the small v- birth of my Bristol 24 hard to see where all the plumbing
goes etc. i have one of these seacocks which i think is a direct drain for the head
as it end off a vented loop there is also another hose off that and an old stye gate valve, but it doesnt seem yo make sense either because of where it is located
i can stick a screwdriver and turn i through the opening and turn it a half turn at a time but i can turn and turn amd turn and it never does lock out one way or the other. i thought maybe they were gate valves and if i turned long enough it would open all the way or shut all the way and then i would not be able to move. but they just turn indefinitely.
anyone who could help me identify this valve and how / what position is opened or closed i would appreciate it. they seem solid and in good shape and not leaking. would rather not pull the boat
just to replace. trying to make sure to figure out what proper settings are to open vs close. plus how to lock shut for coast guard compliance.
when i test the head ( with clean load ) it all goes away and refills etc but i cant seem to find to where etc.
i have tried looking on lines at diagrams of systems, heads etc. mine doesnt make sense comoared to those, but i feel like if i could get confident enough that i definitely have these shut off .... i could either pull the thing out or dosconnect the hoses and then see what comes out when i pump
thr lever on the head
anybody who has seen this or can help. your input appreciated. thanks
