Yet Another Galley Mod

[Jimmyt]

They show with the tank hanging down. Wouldn't it be better with it above the pipes so all the water drains when you depressurize the system?

It has a bladder between the water and air cushion. Orientation doesn't matter. Just one of the advantages of a bladder tank over captive air tank.

Just ran a few numbers. At a 10psi pump range, a 2 gallon tank will only give us about 1.5 liters of usable water between cycles (unless I had brain melt). Unless we can find a pump switch with a larger range, you'd need a silly big (by Mac standards) tank to get much usable volume.

At 0.5 gal/min flow rate, my 1 liter tank should give me 6.5 seconds of flow before the pump switches back on. Not terribly impressive. If you aren't worried about chafing the bladder, you can set the precharge equal to the pump start pressure to get the most usable volume.

A lot of kitchen faucets run around 2 gpm, but they are rated around 60 psi. It will be a little lower at 30 psi.

Any idea what the flowrate is on your sensing faucet? Can you reduce the flow in automatic mode? The kids have one in Birmingham, but I haven't spent much time playing with it.

My scenario was for the nighttime head break / quick hand clean... back to bed. Since our berth will be the front one where the pump is, I got the quietest one I could find (Whisper King). The faucet I have is a bathroom model (outlet about 5" above mount). I believe like shower heads, they have 1.5 gallon/minute restrictors at household pressures. I vid myself washing hands. 1 sec wet (soap / scrub long time) 3 seconds rinse. Soaping out from under sensor and I calculate about 13 ounces of water used (0.38 liters)... so the 2 gallon tank having 1.5 liters usable would be PLENTY!

So you're saying that this expansion tank will do the same thing with FAR more reserve and at about half price!??? And I can put it in any orientation? I still am assuming that if I have the water inlet down, I can completely drain it of water. Don't want it growing stuff over un-used periods.

Yes. All you have to do is find a place to hide it.

I worry about stuff growing in the system as well. The more complex you make it, the harder it is to dry out, or keep safe. If I was living aboard and using it constantly it would be of little concern.

My lower pressure pump came in Friday. It was assembled to flow opposite hand of my original pump. So the first task was to disassemble the new pump and reassemble it like the original. I had remade all of my threaded joints a night or two ago, so it was just a matter of reconnecting and remounting the components and mopping up the spilled water.

Fired up the pump with the faucet open and got the system primed. Then checked the pressure switch settings. On at 27psi. Off at 42 psi. Bled the system down to empty the accumulator and set the air charge up to 25 psi. Prime it again, pump it up to shutoff and leave it to do a leak check. No visible drips anywhere. So far, so good. Will re-check in an hour or so.



Now, to secure the bilge wiring and figure out where to mount the pump on/off switch...

Nice and clean implementation

Forgive the question. I rejoined the forum well into your project and might not have read every word. Did you retain the ability to slide your Galley or decide to fix it solid? I'm interested in any thoughts on the subject by you or anyone else that might have done such an extensive galley project.

Thanks!

I retained as much of the sliding travel as possible, but I don't have the range going Aft of the original setup. The original setup has only three track cars. The front aft corner doesn't have one. It slides off the mount and just cantilevers out over the aft berth. Also, my galley is longer than the original which further encroaches on seating.

I like the sliding feature. If you could build light, retaining the full range would be good in my opinion.

It allows you to have a huge seating area when you want, then you can bring the galley into a more convenient spot when needed. Good concept.

I think what I did will work well for us, as we don't typically need to seat more than 6 in the cabin at a time for dinner/conversation. With the galley slid to its aft location, we can still get 6 in without anyone looking straight into the head.

I'm an engineer with 34 years federal design service to civilian and military customers - most of whom were wonderful - most... There is no question you can ask, or number of times you could ask the same question, that would bother me. I have absolutely no personal feelings left.

Besides, this thread turned into more of a novel, so I don't expect anyone to read it all and memorize it. Blame Russ. He wanted to see how the sausage was made.

Gauge still steady, so looks like plumbing is done. Electrical is last hurdle.

I don't think I could tolerate even 6 on board. Four's about my limit. Maybe 6 if just visiting while on the hook. But 6 sailing... it would remind me of those tourist tour sailing cats in the islands. That ain't sailing.

I like your novel. Maybe, I'll dare to crash and burn or come out smelling like a rose in front of an audience with a big project.

Your gimbaled stove is a marvel of DIY ingenuity. Sometime, you'll have to setup a phone (tied down hard) to video a cooking session while the boat is in a tacking duel. I love me some Sauce Piquante Yummm... ummm... mmm

Better yet... two video feeds sync'd with the Capt'n driving the bus.

I was bold enough to ask the captain of one of those cat’s if I could take the helm of his 60’ catamaran.......he said yes.


First time I (A) Sailed a catamaran, (B) Sailed anything that big, (C) Sailed anything with hydraulic steering.

While in Barcelona, we went on a sunset tourist cruise on the Mediterranean. The boat was a 32’ Sun Odyssey. I asked the captain if I could take the helm.......he said yes also.


Ther were a total of four couples on board, and no one at anytime objected. My wife was asked “how long has he been sailing?”, but then went onto other things.

The cat I sailed for maybe fifteen minutes; the Sun Odyssey I sailed for over an hour. Occasionally the captain would say come about, I would come about. This went on to well after sunset. I took the boat all the way back to the marina, but the captain docked her.

There are no better people than boat people!

(at least to other boat people)

One other option you have is leaving your pump switch off (if your system is leak-tight). Once you get your bladder charge correct, you should be able to use most of your accumulator acceptance volume before the pressure gets too low to flow. Just wait till morning to turn the pump back on.

Just measured usable accumulator Volume after a 12 hour pressure check. Mine flows 325 ml with the pump switched off (about 11.5 ounces), so it looks like a 1 liter tank won't quite meet your requirement, even when we push it to the limit.

If you go to the 2 gallon tank, you can drink another beer before bedtime.

I like the way you think... This is critically important

Nice pics Ray! Thanks for sharing. Looks like a blast!

Well, the place my switch panel wanted to go for convenience was not my favorite for aesthetics. But, after you make the first plunge, you can't chicken out. This will keep my wiring runs reasonably short and have the voltage display and USB charging ports in a semi sensible spot.

K9Kampers, I couldn't pull it off without taking power tools into the boat... Glad I didn't need the table saw!





Now, off to get some marine wire and heat shrink tube so I can wrap this chapter of my novel up.

[Inquisitor]

Not wasting one cubic inch in that normally wasted area in front of the sink. I LIKE IT!

Glad I didn't need the table saw!

Oh... come on. It'll fit.
I guess I won't show pictures of when I take the Sawzall inside.
