I’m not getting hot water through my line to the head sink. Manifold knob for that line is turned on. I switched the cold over to the hot side to make sure the faucet was okay. Another hot water line from the same manifold to the galley sink is providing hot water just fine. Any way to clean the manifold inside? Thanks

Maybe something stucked inside valve? Compressed air should work. Make sure leave other faucet open to prevent from too much pressure build up and possibly damage seals.
 
If you remove the offending hot water line from the manifold... does water come out? What about removing the valve? It would be more likely for the valve to be the issue.

And... you know that it has to be said... are you sure the valve is turned on?

But, generally speaking, as far as cleaning goes, the manifold is simply a tube.

I used a shop vac at the sink end pulling and pushing with no result. The manifold valve is hard to turn but it is open. one of the manifolds was replaced before i bought it. Not sure if it was hot or cold. The release mechanism on that line is in the down position but the line wont pull out. I may have to take it apart section by section. Thanks
 
The connectors could have changed over the years - meaning they could be screw one connectors or push-to-connect connectors, etc. It sounds like the one you are referring to (release mechanism) is a "push to connect"? If so, there's a small plastic (different color) retainer that you pop loose, then push the "collar" towards the connector while pulling the tube out.

If you need more help, can you better describe it? Or can you post a pic?

Once you remove the line from the manifold, you should at least be able tell if the problem is in the line or the valve/manifold.

The center hot water line is the one to the head sink The release mechanism was in the down position when I first started this project, yet the line won’t pull out. Also, it’s hard to get in position to get a good bit of lift on it.

That's good you posted the picture - I was expecting to see a different style of manifold based on your parts diagram for your boat.

So you're saying that working on a boat involves awkward positions and such? Nah, say it ain't so! :)

Try pulling up on the hose... then hold it up while you push the grey ring back down securely. Then try removing the hose while you hold the ring down. FYI... all of those connectors "originally" had a locking clip in them to keep the grey ring from accidently being pushed down.

Once you get it out... another option you can do to eliminate the manifold and valves as a variable... connect your main, hot input line to that center hot line - a short length of garden hose and a couple hose clamps will do the trick. That will 100% determine if the issue is at the manifold/valve or somewhere in that feed line to the faucet.

they make a little plastic tool that makes it easier to push down on the release piece, you should be able to get it at any store that sells pex or any kind of shark bite fittings

If I were 30 lbs lighter and 20 years younger this wouldn’t be a hard task at all but.....
All good information guys. I’m going down to the boat Friday to change the oil and get this manifold thing resolved before winterization. Thanks so much for taking the time to reply.
 
After no luck with a couple compression tools to remove the line I decided to take the 3 line manifold loose to make it easier access. Finally it releases! The manifold comes apart in sections so that other lines can be added. The first (right) section supplies the galley with hot water. Always worked fine. The middle (head) and far left (POS aft shower) hot water lines weren’t working. Upon inspection of the first section I found a divider plug that was not removed when the manifold was installed (eye roll) therefore water could not get to the other lines. I knocked the plug out and all worked well. Thanks to all who contributed.
 
Weird. That would mean it hasn't been working properly for 14 years? Could it be something else that got lodged in there?

But, glad you got it figured out and it was a "no cost" repair!

The manifold was replaced in 2014 because of bad winterization. The boat sat for the next 5 years with minimal use. The previous owner lost interest. Now I’m chasing gremlins.
