A proper enema IMHO is done with an enema bucket or colema setup or very large, 2-quart bag in order to flush the colon with as much water as possible. It should use good surgical tubing with some kind of clamp to interrupt water flow as needed.
A good tip goes a long way to making an enema a comfortable experience. The tips can be simply thinner surgical tubing, or a piece of specially designed plastic, etc. The tip should be cleaned after every use and may be reused.
K-Y jelly is an awesome lubricator. Betadine is a good disinfectent for the tip, for the rest just a weak solution of bleach is enough. About 10% bleach to 90% water.

1 quart very warm but not hot filtered water with 1 tsp sea salt is the basic enema. You should always add salt to soften the water. To this can be added: bentonite clay, chorophyll, acidopholis, and tons of other things for medical reasons, like 1/2 cup sesame oil for constipation. More details at the end of this post.
If detoxing metals, use distilled water, otherwise avoid it.
I like to lie on my back with my fanny raised in the beginning, with my feet on a wooden foot roller. It’s amazing but rolling the feet good and hard will relax all the muscles and colon to allow better water retention. I also press down on my left side, low, near pelvis, to help water move UP the colon. I keep massaging abdomen counter-clockwise as water comes in, and sometimes the outer right thigh, which is a gallbladder point.
Afer taking in about a pint of water (I have to guess this now that I have a metal bucket) I roll over onto my right side to help the water move down the transverse (horizontal part) of the colon, then return to my back to commence more massage of the entire abdominal area and soles of my feet.
I release as needed and go right back to taking in more water until I’ve taken in at least a quart or two.
It’s also good, while retaining water, to squat down and keep massaging the abdomen.
Do not do an enema if you are suffering from diarrhea. DO take probiotics occasionally if you are doing an intense series of enemas, say, after every 7th one. There’s no need to add acidophilus with every single enema.
