Yet Another Galley Mod

[Inquisitor]

Nope. Not sure. Just thinking that with grandkids and non-sailors, the water usage may be a bit less at the lower pressure, in addition to minimizing leak potential.

I won't be throwing the high pressure one away, though.

That was my thought when I put in my measly 30 psi and 2 gallons/minute model. I also use one of those sink faucets that has the LED hand sensor under it. Use water only with hands under it. What size pressure tank do you have?

The sensing faucet is a great idea!

I bought the Jabsco 1 liter accumulator.

Faucet - works great. Beats the heck of trying to figure out mounting/plumbing a foot pedal. And you're correct... land-lubbers don't even think about turning it off between... 1 second wet, 1 minute soaping, 5 seconds rinse.

Accumulator - In one of my more DIY, hair brained moments... I considered using a 2 liter Coke bottle. Still do... my petit model only seems to delay the pump by about two seconds. I would like it to not turn on the pump at all after one hand washing. I volunteer with an 8th grade science teacher to do the water bottle rockets with his students. They take 120psi without a groan. (bottle, not kids) 30 psi is probably less pressure than the Coke fizz creates.

Have you set your tank precharge for the lower operating pressure? 3 psi below cut-in pressure for pump is what Jabsco is recommending, but a lower pressure will give you more acceptance. I was running 10 psi on a cut in of 50. Gave a pretty good run time between cycles. If the bladder/diaphragm can take it, that might give you a little help.

I would guess a coke bottle would stand 30psi. Failure is fairly dramatic, as I'm sure you know. Best one I ever saw (actually only saw the aftermath), was one of my neighbor's kids put some dry ice in a coke bottle and put it in the freezer to "keep it cold". About the time they got to sleep, there was an explosion in the kitchen. It bent the door top to bottom as it blew it open. The handle hit the adjacent wall, holing the Sheetrock. The bottle parted where it necks down, shooting the cap end through the plastic liner and deep into the foam insulation. I felt sorry for the kid, but had a hard time holding back the laughter.

EDIT: Actually, the ideal gas law balanced against the diaphragm elasticity may make monkeying with the precharge almost insignificant. Your idea of a bigger acceptance volume is the way to significantly increase pump off-cycle duration.

Hunhhhh? There's settings? Boy! don't I feel like a DA. Must have been one of those, "Direction's, I don't need no stink'n directions!" moments.

As long as you had the factory precharge, you were probably getting pretty close. You could try going 3 psi below cut-in and see if it helps any. They usually come with some precharge from the factory...

You replied while I was still mulling... did a lot of expansion tanks, but very few accumulators. Never had to set up an accumulator, but have done my share of expansion tank setup. Virtually identical but slightly different goals in mind...

Takes me a minute to get the neurons going sometimes.

And... here's why accumulator manufacturers recommend precharge pressure be slightly below min operating pressure. Keeping some water volume in the bladder will keep the bladder from chafing on the water inlet port...

Aren't you in a bunker somewhere... or do you have Internet in the bunker? Isn't the Eye right overhead? Take care! See you when the sun comes back up.

Showtime starts in about an hour and a half. Just breezy and rainy now. It's going to miss us a bit. They are predicting around 50 mph steady, gusting to 70. If we don't get a tornado, it should be manageable.

It's moving fast, so it should be over around 11pm. Unfortunately, my kids and grandkids are in the track further north. More worried about them than the Admiral and myself.

We'll move into the Mac in the basement if it gets too hairy. If we have power, we've got wifi. Topping off the house battery so we can see to play cards or read.

Shore power tends to get scarce as these things go through.

And thanks for checking!

It's headed your way after it's done with us. Hope you're in the eastern part of the state... then, it's visiting Tomfoolery... hope everyone stays safe.

We're in western NC and we get to share the joy! We're in the cone now.... but all we'll get is a dumping of rain. Never have seen a hurricane last long enough to give us even sailboat wind.

Dude! I just zoomed in on your pic. You got the Shurflo accumulator. I think it's factory precharged to 30psi. Guess how much water it holds with a 30 psi pump?

Good news is, easy fix.

We got power back today around 2pm. Blew a lot more than I was hoping for. 70-90 mph at the airport about 5 miles west of me. It was fairly rowdy, even down in my dip in terrain...

Yard is clean and power is on. Boat is safe. Kids all made it through the storm without damage. (Not listed in order of importance). Life is good here.

If you want meaningful pressurized storage, get one of these and set the air charge 2-3 psi below pump start pressure.

That's great news. Even though our Zeta winds were not even good sailing winds, we lost power for about 12 hours from downed trees. Just now getting back in the saddle.

Its an interesting thought.

I put one of these in my old house. Newer code required on replacement of the water heater. 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?
