Re: Stus-List Gate Valves

[Randy Stafford via CnC-List]

Thanks Joe, that's good news on both counts. On my boat the PO re-bedded all 
valved through hulls four years ago, but left the gate valves on the cockpit 
drains. The through hull for the vanity sink drain / head water intake, and the 
through hull for the engine cooling water intake, already have seacocks on my 
boat. I'll put replacing those gate valves on my project list. :) 

Cheers, 
Randy

Hi Randy, 

I replaced the old gate valves on my 30-1 this winter. While trying to 
unscrew them, I ended up spinning the actual thru-hull so I replaced those 
as well. I had a devil of a time finding the replacements since on my boat 
#305, they were flush to the hull. I found some flush thru hulls that had a 
slightly smaller flange diameter than the originals and just filled in the 
extra space with some epoxy filler. Both gate valves in the cockpit were 
failing as well as the one in the head. I wasn't as big a job as I had 
feared and it sure feels good to have them up to snuff now. 

BTW, I also did the mast foot repair a few years ago. The worst part of 
that was taking out the mast - but the repair was easy and relatively cheap 
and should last another 40 years. 

Cheers,

I bit the bullet and replaced all my through hulls and replaced the gate
valves with proper seacocks.  The forty year old (at the time) plumbing
just didn't inspire confidence.

Gate Valves are no longer approved by ABYC.

While I'm at it, Casey also writes that plastic (Marelon) 
through-hulls should not be mixed with bronze nuts and seacocks, which 
my boat does.  He writes only plastic nuts and seacocks should be used 
with plastic through-hulls.  Thoughts on that one?

Gate valves should not be used ( despite their use by Benne, Jennaeu and
others).  Thread types should not be mixed.

I had a gate valve failure on my previous boat.  The shaft corroded in the
gate.  The handle and shaft spun freely but the gate did not move.  I had
no way to know if the gate was open or closed.

As I recall, the reason they shouldn't be mixed is that Marelon fittings have 
straight (non-tapered threads) while most bronze fittings have tapered threads. 
 If these are mixed the softest material of the two will have deformed threads. 
 I have been careful not to mix them for this reason.
