FILLING PR SYSTEM ONE HUMIDIFIER WATER TANK

HOW DO FELLOW USERS MANAGE TO REFILL THE HUMIDIFIER WATER TANK WITH OUT IT LEAKING? I HAVE TRIED JUST ABOUT EVERYTHING I CAN THINK OF TO REFILL IT AND NOT HAVE A LITTLE OR A LOT LEAK OUT WHILE FILLING. TRIED POURING REAL SLOW, JUST A LITTLE AT A TIME, HOLDING A FINGER IN THE AIR INLET TUBE HOLE IN THE MIDDLE OF THE TANK WHERE IT LEAKS OUT, I HATE HAVING TO TAKE IT IN THE BATHROOM OVER THE SINK. AS GOOD AS THE PR S 1 IS, I WOULD HAVE THOUGHT THEY WOULD HAVE COME UP WITH A BETTER REFILL METHOD. WOULD APPRECIATE HEARING ABOUT YOUR PROCESS YOU HAVE DEVELOPED THAT DOESN'T LEAK ALL OVER.

Oh, yes, the maddening PRS1 humidifier tank. It is not only bad design, it is sneaky - water lodges somewhere in the works and holds there for a few seconds before dropping into the tank - leading to infernally easy overfilling.

I tried everything - squirt bottles with nozzles, pouring to the side, over the sink - and the only thing that really works is to remove the top of the tank entirely to fill the base, and then replace it.

(I resisted that because I seem to have a little trouble getting the latch lined up properly at night when I'm really tired and my eyesight is fuzzy.)

The one thing I thought of that I didn't try was to connect a piece of silicone aquarium tubing to a nozzled bottle, and then insert the end of the tubing through the top opening into the bottom of the tank. I think that would work, but removing the top of the tank seemed simpler since it doesn't require me to decant the distilled water into bottles.

I'll be very interested to hear what others have come up with on this.

The lid will come off.
I filled mine in the bedroom...on the bed... with a gallon of distilled water. Had a few accidents but none really bad.
I didn't even remove the lid...I did have to tilt the tank just a little to bypass that overflow hole.
I was just careful to poor slowly and check the water level. I pretty much have always had to top off the tank nightly ever since I started therapy.
With the PR S1 I didn't even realize that the lid would come off for 4 months.
A small funnel might help if some is a bit nervous or shaky and doesn't want to remove the lid.

Agreed. This is a design flaw in the PRS1's humidifier tank.

The trick that works for me is to NEVER try to fill the tank to its max fill line. Pour slowly and stop pouring when it reaches about 1/2 full. When the water finds its way to the bottom of the tank, it ends up closer to and not over the max fill level.

I don't use that much water in my humidifier (I use it at setting = 1) and I find that I easily get 4 or 5 nights from one of these "fillings". An extra night or two that might be achieved by filling to MAX is not worth the hassle of cleaning up spills.

I just stick my finger in the overflow hole and tilt a bit as described above. Sometimes I get a drip or two but usu. don't sweat it as it is pure water and will add to the moisture of the room soon enuff.

My only secret is I do NOT fill it all the way. I only add enuff for a couple days.

I am opposed to removing the top or pouring into another container as both will increase the collection of other debris AND is more work for me

I think most people never realize that hole is to let out the excess water once it has reached its capacity. Try filling it only half-way to see if you are still having the same problem.

I do like this tank design tho. It is simple to take apart and put together once you know the little press tab is there. That means reading the manual.

When all else fails - read the instructions.

What I don't like is I have to remove the tank to see how much water remains as I keep my machine on the floor.

That is my story and I'm sticking to it.

Like the others, I just fill the tank 1/2 way and I rarely have any leaking...
I don't think there is a design flaw -- remember, this is "dry box technology", it was specifically designed to make it very difficult to ruin the cpap unit if the cpap unit/humidifier are moved with water in the humidifier...
though I must admit this design doesn't make it easy to fill the tank...I suggest just opening the tank if you still have leaking...

I DON'T LIKE TO HAVE TO REMOVE THE LID TO REFILL IT EITHER, AND ON LOOKING AT THE INNARDS WITH A CRITICAL EYE, IT SEEMS THAT IF THE END OF THE AIR INLET TUBE, WHERE THE LID LATCHES, WAS CUT BACK ON A ANGLE, THAT THE WATER WOULD NOT TRY TO ESCAPE WHEN YOU POUR WATER IN THRU THE TOP WHERE THE AIR OUTLET IS. I HAVE AN EXTRA TANK HANDY AND THINK I WILL TRY CUTTING IT BACK AND SEE IF THAT MAKES A DIFFERENCE. WILL DRAG SOME TOOLS OUT AND SEE WHAT HAPPENS. STAY TUNED.

OH, AND I DID READ THE MANUAL WHEN I GOT IT AND DECIDED I DIDN'T WANT TO REMOVE THE LID TO REFILL...

Looking at this design again, with a critical eye; to me it looks like it is the locking tab which reroutes some water out of the overflow hole. And I would think that cutting that overflow tube at any angle will only cause it to leak more. But do let us know how you make out.

the problem is that the center part fits too snugly when the top goes on. when you fill it a certain way water gets in the crack of the center part of the top and the bottom and causes an airlock so the center fills up but it don't fill on the outside causing water to go in the tube and run out. when this happens pick up the unit and jostle it around a little before the center overflows. put a little in and if the level does not rise, jostle it around and you'll see the water come up. generally i fill mine with a small bathroom plastic disposable cup and do not have overflow problems. the trick is to pour it so it doesn't get on the tube. when it gets on the tube the airlock starts and you have overflow.

really, seriously, like it or not, bad design or not, it is much easier to take the lid off and fill it. the lid comes off very easily and it's simpler putting the lid on than cleaning a mess. swe have 2 of them. i do this twice every night.

I've never had an overflow problem. I fill it from the top straight from the R.O. filtration faucet. When I'm done filling it, I'll tip it toward the air intake port and dump any extra/overflow water. My 9 year old fills it all the time for me without any problems.

I had that problem of overflow when I first got it. I never removed the top while filling. Now I just take off the top when I fill it and no more problems. I keep a towel underneath in case it drips which it usually doesn't.

I don't know why some of you folks don't like to remove the top. It's super easy to remove and easy to fill right up to the max fill line. I often use most the water in one night (I am in the AZ desert right now and it is dry) so I like to get it full.

I can't imagine ( unless there is a medical or physical problem) why filling the humidifier chamber up with water on the PR System One, could be so difficult.
Take the top off...leave the top on.....Hold it under the tap, pour it in directly from the distilled water jug, use a measuring cup, use a funnel.
THere are no tricks to solve. It is designed the way it is after many hours of design and testing, so that consumers don't spill water into the machine, because they forgot that it has water in the chamber when they go to move it.
FOr those who can't or don't want to take the top off...how are you cleaning the inside??

I use distilled water which requires absolutely "NO CLEANING" but that is another topic and probably hasn't been beat to death enuff times already.
