3 position sea cock?

[mrscotty]

Hi all, they will be nearly 40 years old if original, they live in a 14 inch void in between 2 bulkheads so im guessing failure would not be the usual catastrophe.
Thanks again.

Manateeman Mark:

I’m pulling out ALL the plastic / Marelon junk valves which was a huge mistake

I removed all seacocks and had the decision to go for marelon or groco.
I did it with the grocos.

I think it ist an valuable input for a lot of owners if you detail the reasons why you deny marelon.
Thank you,
