Joining the heard on seacocks..

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm becoming guilty of heard mentality after reading on these forums about replacing Hanse's standard seacocks after 5 years...
I'm sure it's a bit over the top, but since I have one that is stiff anyway and next winter the boat will turn 5 years old I'm thinking I may do it this spring.

I'll only do the below waterline ones, so on my 418 that's; The heads inlet, holding tank outlet, galley sink outlet and maybe the saildrive. The through hull skin fittings are already plastic, so I'm thinking of fitting true design for the valves. Anyone know of the sizes involved? Also, any recommendations on jointing compound?

Thanks

	Sorry I can't help you with the sizes for your boat, but I was all set to replace the seacocks using the existing Tru-design thru hulls on the 345 earlier in the year when the boat was out for a quick weekend lift out and I found that the valves were very well bonded to the plastic thru hulls. Not wanting to get caught with a seeping thru hull or worse, I deferred the job to the next longer lift out and I now have replacement thru hulls as well. They're not too expensive in the overall scheme of things. FYI

	are you seeing noticeable degradation of the valves, or just being preventative? The ones on my 2014 look brand new and of similar brand / quality of what i would get to replace them...?

	If you are sailing in a lake, you may expect a lifespan of 10-15 years of your seacocks. But! - if you sail in salty water, do like Hanse Werft recommends, and change after 5 years. On the outside, the brass looks like new, because the damage is on the inside of the seacock. https://www.myhanse.com/new-seacocks-thruhulls_topic10598_page4.html

	hello Matt1 As another post commented - more critical in salt water - the through hull component is Trudesign I believe and the replacement seacocks simply screw in with a matching Trudesign seacock - you may seek advice from others but I found that the manufacturers website provided all the info I needed together with Sydney agents advising to use them as well as others- in the industry I trust - If you think it is not an issue and wish to check, simple close your main toilet seacock then very carefully remove the 2 clips and very, very carefully twist and remover the hose - be prepared to be converted to the herd advice if your boat is used in salty water and a salt water flush - if I could work out how to post a photo I would show you mine - the side wall of one virtually crumbled in my hands - I also replaced the seacock on the sail drive keg with a bronze replacement although the Volvo agent inspected it after removal and said it was all ok.

	A comment on the way to post photos and documents: "Quick Reply" is for text only. "Post Reply" (Find the button on the left hand side) will give you the choice to add a file(pdf), choose the icon to the left of the tree. The tree-icon "Insert Image" opens the opportunity to add a photo, but most photos are too large, since the limit is 256Kb. There are a lot of free programs to shrink your photo. I use ViewNX2 from Nikon. :Kjeld Edited by Captain Cook - 23 January 2023 at 17:36

	We had pin-hole leaks after just EIGHT years. Replaced all below waterline fittings with TruDesign. Cheers.

	thanks CC Downloaded an app and this is my “result”- Sea Rambler was launched in May 2014 and I changed them in January 2020- the side walls were very brittle and crumbled when the hose was being removed -
