Attached is a photo of one butt connector I like (just
the circled wing-nut caps and gaskets, which fit over
the water lines we have in our Pearsons). Anyone know
what these are called, who makes them and/or where I
can order them?

Tor

Tor,

The slip on connectors are available at Home Depot, but Sea Tech is
probably the ones you’re looking for. Pearson hoses are 3/8″ ID, 1/2″ OD.

They’re not terrible expensive and you can order them online. They’re the
ones I use and use on customers’ boats.

One or more in this group have modernized their

Pearson used. The old ones are oversensitive, leak
easily and strip their threads with little provocation.
Can someone – Pete Dubler, maybe – tell me the name of
a new, improved version of these for connecting the
freshwater lines throughout the boat?

Thanks,

Tor

I believe they are John Guest fittings. 1/2″ OD tubing. X 3/8 or 1/2 mpt. Pretty cheap in bulk online. I thought I had replaced them at all the sinks and found a leak from an original fitting just two weeks ago… I keep extra John Guest fittings onboard

They work, too. I think SeaTech is less expensive, but I guess it depends
on the source. Basically the same things. If you want to spend lots of
money, Shark fittings are great, too.

Bob/Pete,

Thank you both. Either brand – SeaTech or John Guest –
looks like what I want. I’m just trying to figure out
which model I need for these on board connections. I
know the hoses are 1/2″ OD. x 3/8″ ID. The boat’s
faucets, galley and head, offer a threaded female pipe
that appears to be 13/16″ ID, but I don’t think pipes
are measured that way, are they? So, any idea which
model or series SeaTech or John Guest will connect that
hose to that threaded female pipe?

I also want to add on/off valves to the connections at
the water heater (same size female threaded pipes).

Tor

Hi Tor,

The fittings for faucets are standardized – I think they’re either 1/2″ MPT
or 5/8″. There are standard faucet fittings with a gasket that will take
the plastic tubing on one side and the faucet on the other.

Google said MPT is Maryland Public Television.

OK, Bob. I’m measuring 13/16″ ID on that pipe fitting. Allowing for senility, it’s most likely the 3/8″ MPT that will screw into that threaded female pipe. Ergo…

Am I correct that I need the SeaTech or John Guest quick connect fitting that accepts 1/2″ hose at one end and boasts a 3/8″ MPT at the other? In you professional opinion (but without the fee), is that what’s going to connect those two disparate items?

Both manufacturers make various fittings. The one you’re looking for is
tubing to faucet.

Man, I have to say their website sucks. I am not without some experience at this stuff, but I can’t figure out what fitting does what, how it works, and what it has to combine with to accomplish the very simple task I need accomplished. NPS, closet, FGHT, for heaven’s sake. How do they expect anyone who isn’t a Certified Plumbing Professional to know what to use here? Lots of photos, but not one – not one! – showing the inside workings to illustrate to us morons how the fitting functions, what unscrews, where the hose enters, how it butts up to whatever and remains watertight; nada. Nothing to suggest, “Here is a fitting that will take a 1/2″ OD hose in one end and connect to a threaded female pipe at the other, or a male pipe fitting, in which case here is the female-to-male adapter.” There is no way laymen can order from these guys with any hope of getting something useful. How do you do it? I mean, aside from being frighteningly intelligent?

OK, that’s my morning rant. Maybe tomorrow I’ll send it to their customer service department and see if they can tell me what parts to order.

Go to Utube and search for the type of fitting you are interested in. You
should be able to find some instructions and explanations.

Thanks, John. I actually just came across those YouTube

link to them or include them on their websites. (Or
maybe they do and I missed it.) I’ll wait for them to
reply to my “which fittings” query and then order what
I need. I’ll be glad to be rid of the old, original

Tor,
When you get started I may drive down to give you the benefit of my
supervision[?].
I have been planning to replace all of the water hose and fittings for
several years, but just can’t seem to get enough ambition to start. One
thing I would like to do is install a deck fitting to allow me to take dock
water directly to my faucets, bypassing the tanks and pump. However I have
been unwilling to risk putting city water pressure (even when regulated by
the deck fitting) into those 35 year old hoses. For me the biggest
impediment is figuring out how to do the installation and minimize the
amount time my system is down. I will probably take it one section at a
time (galley, head, and forward cabin). That will extend the project, but
maybe I won’t have any one section down for more than a day or two.

Regards,
John Stevenson

John,

Silverheels came with that dock hose deck connection
already installed in the outboard side of the port
cockpit combing, and I’m glad for it. I’m almost never
dockside when I’m cruising, but here at my home port I
am and I use a dock hose as you’re proposing to do.
You’ll want to buy a pressure regulator, which simply
screws into the deck fitting. The dock hose screws into
that. I’d say it’s an absolute necessity. City water
pressure varies greatly and will often exceed what our
boat systems can handle. A buddy of mine very nearly
sunk his boat at the dock once because he neglected to
install a regulator inline. Naturally, the internal
hose or fitting that burst did so while he was away
from the boat. Fortunately he returned before it was
too late, but it was a close call. With the regulator,
though, I believe it’s a fairly safe system. Of course,
I don’t leave the boat for longer than local
day-errands without shutting the water off at the dock.

I don’t recall what the regulated pressure is offhand,
but Silverheels’ original plumbing has handled it
without incident. I did replace the hose between the
deck fitting and the manifold beneath the galley sink,
along with much of the other plumbing and hoses in the
boat. But the hoses and fittings that carry freshwater
to the faucets and shower are original.

As for living temporarily without pressure water
aboard, invest in a 3-gallon insecticide can from Home
Depot. The attached clipping from SAIL explains it.
That has been my shower this past week while I’ve been
installing a new shower faucet in the head, rebuilding
the old head sink faucet, and so on. You can also bring
it into the galley to wash dishes, etc. It’ll take some
of the inconvenience out of working on your boat’s
freshwater system, and thereafter it’ll provide a
mobile deck shower when you’re cruising.

You know, Tor, how sailing has its own vocabulary? Well, plumbing does,
too, even on a boat. All faucets have standardized fittings (at least here
in the US). They can be one of three types, one, like you have, is a 3/4″
fitting that has a nut that has a gasket in it, like a garden hose. That’s
the closet fitting, I think (which actually means ‘toilet’, closet for
water closet). The other is a female compression fitting, and the final
one is a male compression fitting.

Anyway, I could go all plumber on ya, but you get the idea.

I assume that’s a rhetorical question, but in case it isn’t, I was a
Nuclear Machinist Mate in the USN, as well as Engineering Laboratory
Technician. Before that, I broke and fixed more cars than most people have
in their life times. After that, I learned welding and machine shop work.
Then, built a house (or pestered people building one), and now repairing
other people’s boats.

The secret is knowing who to talk to in the plumbing store (take a part in,
frown or whimper depending on it’s importance, and wait for the guy to go,
“Oh, that’s a frammistammel – a half inch one. I’ll be right back.”)

The same things break all the time. If it’s broken on your boat, it’s been
broken on mine, and since I’ve already fixed it once, it’s easier to do on
yours.

Oh, and tools. You have to have lots of tools. Some you find the purpose
for only after you’ve purchased it. Of course, then you have to find a
place for it. There is no doubt a special tool for the frammistammel, and
I no doubt have it but there’s a huge doubt about me finding said tool.

Anyway, that’s my story and I’m sticking to it.

On the other hand, I couldn’t sell heaters to Eskimos.

Tor,

I redid the distribution manifold on Easy Reach in 2010 with push and click fittings. I can’t remember the brand I used and it took some effort to properly engineer the layout and get fittings that would work in the confined space under the galley sink. Expert advice was not readily available. Had she not been on the market, redoing the whole domestic water system would have been on my wish list. 

I’m not home now, but I may have some records that I can refer to find the brand names. I recollect there were at least two and I used the one carried by the local yard in South Amboy, NJ so I could play with pieces in the chandelry before taking them to the boat.

Here are the ones I used on our 424. These worked on all the sinks and

Thanks, Pete. Are the threaded female bronze pipes at

changing that threaded female pipe end into a threaded

the John Guess quick-connect fitting at the end of your
