That old bolt together ShurFlo was rated for WH use and was OEM on my ‘84.

Raritan specifically states re its RCV valve:
“Not for use on pressurized lines.”

I installed the Raritan check valve on my shower sump line.  Just like the post says.  That line is under suction.

The only point of my posting the pictures was to answer ba's question about the looks of the two different valves, and what my remaining heater valve is.

I don't think that age of the check valve is a negative here. Ken said that the older ones bolted together and were pressure rated. At some point Shurflo changed the design to a heat-welded one. Not sure when that change was made, but your 32 year old one might be better than the newer ones. Does yours bolt together, and allow disassembly to clean the flapper?

Here's the pictures, should answer your question, too.

Golly, I know exactly what check valve we're talking about.

One option is that if, as ba says, things start goin' south and pressure really builds, when the check valve goes, it could go along with the "...hoses, barbs, valves, and pump..."  IIRC, most pumps have check valves on the outlet, too. 

By then, one could/would have bigger issues than an old check valve.  Which on my boat has been working for 32 years. 

Of course there are better valves, and incremental improvements and enhancements are always welcomed.  I'm  just suggesting we put this in proportion.

Your boat, your choice.  :D

I'm confused.  About the system pressure.  My domestic water pump is rated for X gpm at about, IIRC, anywhere from 40 to 55 psi.  The T&P safety release valve on the water heater appears to be there in case the heater itself has created over temp or over pressure.  But if the water system PUMP can only produce a max of say 55 psi, then what's the issue with the old check valve?  Sure, if the system clogs up and the pump keeps running, maybe, just maybe, that 55 psi could be exceed AT THE LOCATION of the check valve, but if that's ALL the pump can produce, where is that extra 100 psi coming from?

lucky,

I forgot to mention that the IJPE measurements are included in the C34 owners manual, available in the tech wiki in case you don't have a hard copy.

I have long link plates on my furler, and the standard OEM 110 jib I have, not made by Catalina/Ullman but by Leading Edge, a very good San Francisco sail maker back in the 80s, gets the clew up off the deck for very good visibility.  The cut of the jib appears to be identical to the OEM C34 working jib, just that my PO bought his sails from a local vendor instead of getting the stock sails, because back then the stock sails sucked.  After a few years, in the early 90s, Catalina finally improved the quality of the stock sails by Ullman in Southern California.

OTOH, the skippers I raced with back in the late 90s & early 00s, all had 130 deck sweepers.  Our Fleet 1 PHRF ratings gave us a handicap for furlers, off the deck and smaller headsails (i.e., less than 130).  Because the racing skippers were true Corinthians, the handicaps as developed over the years were and remain a true model of fairness for all competitors.

I've had one of those "crappy" check valves in my water supply under the galley sink for 32 years on my boat, still works just fine.

I replaced the one under the head sink to the shower sump with an inline Raritan check valve.  The shower sump pump, IIRC, is in a different place on the Mark IIs. 

I posted pictures of the old and new years ago, I'll see if I can find it.

The measurements are based on the luff perpendicular.  You determine the height of the clew.

I ordered the Camco 2-valve bypass kit from Amazon, so I may have additional questions after it comes in. In the meantime, here's my WTF moment from today. What's wrong with this picture?

Dunno, could that simply be the check valve?

Cliff, I recommend doing a search here on "cubic feet" and you'll find some answers.

Why bother with the pushpit modification?

That's what we had before and let me tell you Stu that the comfort difference is worth the money for us since we use them every day.

I hear you, Rick.  I only offered that with the pictures as a solution for those that don't have the $$ to replace their pushpits, to show it can be done on Mark Is (just in case they didn't know).

I think we all agree they're used regularly and the best seat in the house.

OK, here's the first one I found on the C36 site from a search on "damper plate".  Many more show up, for different engines.

https://www.catalina36.org/forum/technical-discussion/damper-plate

Now that you can get to the C36 forum so easily, please feel free to search away there.

Please also let us know if/when you find something pertinent to your question.

Good luck.

Nice report, thanks.

IIRC, the C36 skippers seemed to have more transmission and damper plate issues than "we" C34-ers ever have reported.

I'll go poke around the C36 Forum.  You could, too.

Also superb of you to post about something BEFORE you did and wondered...doh!

Thanks again for bringing up this issue.  I still have no idea why the C36 folks had to suffer:  same engines, essentially same boat.  But they have recorded and shared their experiences.

Now we just gotta find it.  :D

Thanks, Noah.  Mine looks like that, but doesn't have the connector between the two halves, and mine appears more of a hard plastic than the WM picture, which would seem to need to be somewhat "squishy" to make the seal and the tow parts come & go.

I haven't yet hooked it up to a 12V power source to see if there's anything inside the danged egg yolk!  Maybe it's something like "Yeah, when you are ready to use this pump, get a fuse holder that looks like this, but one that works!"  'Cuz if I install it and the fuse (?) blows and I can't get into it...doh!

Who knows...

And I also thought about Ken's idea, too.  But he & I have had this discussion before: everything on my boat is glass fuses (yeah, the boat is that old!!!) so it would make little sense to start with different fuses now.

Thanks again.

Stu,
Could this be linked in the Tech Wiki under “Transmission”?


Dave,

Good idea.  Done, Halloween Day 2019!!!  I modified the title of this thread, too, to show what it covered.
