Filling Up, with gravity?

I see that alot of pics have "bags" ( hot water bottles etc ) that appear to gravity feed.

I have tried this & it doesnt seem to work very well.

I did use an open container, so I have used an air tight vessel to hold the liquid?

Probably you didn't fill the tube that connect tha bag with the nozzle! if this tube contains air, the liquid doesn't flow well or not at all! You must hold the nozzle at the same level of the water in the can, open the clamp and let the water flow into the tube. Then close the clamp and keep the tube full of water. Then soon begin your enema, or the water in the tube will become cold and will be painful at the beginning of the enema, spoiling enema's enjoyment!

With out some type of pump I know of no other way to receive an enema. Bag height (can, syringe, whatever) will not flow unless the pressure is greater outside the body than inside. 3 foot height difference for some is perfect for others, like myself, a 6 to 8 foot height difference may work better.

I hang my 1 gallon bag from a hook in the ceiling and have 10 feet of latex tubing attached. The temperature of the water in the bag must be a little higher than normal due to the heat loss as the liquid flows the length of the tubing.

No two people are identical in what works for them. What works for me may not be something that others want to try. You know your body better than anyone. Pay attention to what you are doing and if it hurts, STOP!

If you are getting no flow from a gravity setup I would first check your equipment. Check the tubing for “flat spot”. Often times the cheap plastic tubing that comes with most bags will collapse or kink when bent or folded in storage. I would remove the clamp after each use and hang everything to dry after cleaning. Replacing the tubing with latex is a better option.

Moat all home centers sell Latex Tubing by the foot. It is used by woodworkers as a clamp for odd size or odd shape items. It is also used as a large rubber band for holding trash bags in the can, exercise bands for seniors, drain hose for heat pumps and so on. It is a quarter inch inside diameter and last a very long time.

Heres a little trick for you fill the bag i am assuming its a cheap drug store 2 quarter till its full then take the hose (replace with natural rubber from a hardware store) and attach a water filter adapter to your water faucet it has a valve to turn on/off and has a barbed hose adapter on one side stick the hose on and let it flow out the end you screw on the bag when there is no bubbles screw it on the bag. Now for the fun part with the hose still attached fill the bag till it almost busts 4-6 quarts and hang it high use the cheap white ramp clip to get the desired pressure. Also on the rubber hose roll the ends to the outside to stay on the bag better also you can stick the other end up your hinny without putting on that cheap enema nozzle "ITS KINDA LIKE A COLON TUBE" enjoy!!

I use a combo enema/douche open bag and have no problems with gravity feed - the only way I keep the water from moving is to close the clip.

Here's a lesson in fluid physics. If you want more info, check your Halliday and Resnick text. You do have one, don't you?

1--The solution in the bags we use, unless we pressurize them somehow, all flow into us by gravity. A column of water exerts approximately one pound of pressure for every 27.68 inches of water column height (INCLUDING the water height in the bag).

2--All the air in the tube must be expelled for the water to flow smoothly.

3A--In an OPEN TOP bag, the height of the water column CHANGES (goes down) as the bag empties, hence, the pressure when the bag is full is higher than when it is just about empty. If your bag is 12" tall, the pressure will be about 0.43 psi less than when it was filled to the top. You can see the level of water go down in the bag.

3B--In a CLOSED TOP bag, if you completely fill it to the top, the height of the water column STAYS THE SAME HEIGHT as the bag empties because no air enters the bag as water flows out and the bag approaches being empty. Therefore, the pressure in a closed top bag STAYS THE SAME from the time you first open the clamp until it is empty.

This IS how it works. If you need more explanation, see your Halliday and Resnick.

I usually keep the height of the bottom of my bag between 3 and 5 feet above the floor and use the clamp to adjust the flow as necessary for comfort and the flow rate I want.

Switchablesusie,

i often learn much from reading your posts, but your last one on 'gravity' showed me how much i still don't know about the 'art' of enemas. thanks for the posting.

^^^^ You're welcome! 😉

Never had a problem with an open top bag, or other open container, with a 3 foot height difference. It is sometimes slow to get going. I overcome this by taking deep breaths and moving the nozzle about. Once flowing no problem.

If you have trouble perhaps you should try a Higginson pump but it is not easy to relax unless you have a partner to do the pumping.

I'm not going to get in to the science behind this, but your problem is that you have TEN FEET OF TUBING. It takes a *LOT* of pressure to push water that far and for it to still have enough pressure to actually enter you. Doubly as much if the tubing is looped a few times hanging vertically on the wall. The numbers get even worse as the diameter increases too.

I've had this problem before. Try cutting the tube in half and you'll immediately notice how much faster the water flows. If that doesn't work, get a smaller diameter hose. Anything bigger than an inch will require you to squeeze the bag (hard) to get it to flow.

Physics -- More than a good idea, it's the law!

A shorter tube, given the same column height, will flow faster because there is less resistance flowing through the tube, however, the pressure at the end of the hose will be the same. The flow in a long tube is more affected in a NARROW tube than than a thick one. The number of times a vertical loop is made in hanging the hose versus laying the tube in a tangle on the floor doesn't matter. The flow rate is determined by the column height and length of the tube, which adds resistance to flow, but not pressure. A smaller diameter hose will slow down the flow more than a wide one. You want a wide bore tube for greatest flow.

Yes but it still requires more pressure to move than smaller hoses -- it has MORE mass to be moved against MORE surface area. For pressurized systems using a large hose is fine but for gravity fed systems I wouldn't use anything over a 3/4th inch diameter. Either way, never more than 6ft long.

I have a 1.25" diameter tube that I used in a pressurized system just fine but when converted to gravity fed it would just pool in the tubing and stay there no matter how far I raised it. I cut it down to 6ft (was 12ft) and it actually worked somewhat. I'm thinking about donating it to a frat house as a beer bong 😜

You are very right about it not mattering if it's looped up or not, that only applies if the hose isn't primed with water. My bad.

Sorry all, I picked the wrong day to get all science-y. To quote the Cheshire Cat, I'm not all there myself.

I'm tempted to actually run some numbers on this stuff...

And Susie, thank you for your help on this.

ALSO, none of this really matters if the hose doesn't go below the entry point. I think. Yeah, screw it, I'll do some math and some hard experimentation and find out for sure 😃

Hey Zippy, now everyone can have their own copy of Halliday and Resnick!!! 😁 😁 😁 😁 ;

I, of course, have the eh-hemm, "older" edition. 😁

I have no trouble with gravity.

I think you will find that an open top bag will give you a perfectly good fill. adjust the height you hang the bag at and you will find that the higher you have it, the greater the flow will be. try it first into the sink. you should have at least two metres of hose to allow for sufficient height adjustment and for you tp be able to position yourself comfortably. there is nothing wose than a short hose which leads to pulling out the nozzle when you turn over! Panic ++

I hang my 4 quarter from the shower curtain holder. As I stand up for my enemas, the bag is about 2 feet above my anus. I have a higgins attached between two 6 foot hoses for mobility and flow control.

I use a combination enema/hot water bottle for enemas. I fill the bag and let water run through the tubing to get rid of air. If I'm standing, I position the bag at least shoulder high or above for desired rate of flow. If you have any constipation, be sure that fecal matter is not blocking the rectal tip.

Something that I do every time I use my closed bag is I blow air into it through the hose after it is full of water. Once you turn it upside down and let the air in the hose out, there is still an air bubble above the water that helps force the water out. I've noticed that unless I do this, there will always be water left in the bag once the flow has stopped... Not to mention the look of the bulging bag drives me crazy.

I just discovered your post on fluid flow and gravity. I got a kick out of your reference to H&R. I thought I was the only one who read engineering(EE) and physics texts.Excellent information by the way and (I think) a strong endorsement of a closed top bag. 😎

^^^^ Actually, I have a preference for the 4 quart open top Klystra silicone bag because it is very well made and I can add water to it if necessary without disassembling anything in the midst of an enema.

The minor change in pressure doesn't really make a difference to me since I hang the bag 3-5 feet above the floor and that is enough pressure to fill me up and for water to get past any blockage (with abdominal massage) if one ever occurs.

An open top jug with the hose pushed to the bottom and tied to the jug, so it can't slip out. The start a syphoning action, let all air pass through the hose, and insert. That way you can see the water level drop as it flows into you. On a good day, it drops quite fast.

I always use a gravity feed for my 5 Qt silicon bag and colon tube at a height of about 6 feet above ground and me sitting on the toilet.

The flow is not that fast but thats part of the pleasure.

Here is the perfect method i have found to fill my closed top enemas with a very crampy 3 qts of rich Ivory soap solution. prepare your solution but prepare perhaps an extra quart or more of soapy solution. fill the bag as you normally would. hold the bag up with the clamp open until the water comes out. close the clamp and place the bag on the floor. now while holding the nozzle in the extra container open the nozzle. keep the tip of the nozzle completely in the container! watch and you will see that a siphon has started and the bag on the floor is filling itself beyond its 2 quart measure. i place a small hose clamp on the tubing where it attaches to the bag because the extra pressure can sometimes cause it to pop off. fill it as full as you dare. now admire it and think to yourself where every bit of that that rich soapy water will soon be going!! enjoy!
