I have used enemas for years to help wash out my j pouch. What works for me is to remove the little check valve flapper from the top, and dump the saline solution out.The saline water kinda stings. Refill with warm tap water. I reuse the bottle over and over, making sure it's clean each time. When the plastic cracks, and the bottle starts leaking, it's time for a new bottle. I even keep a bottle wrapped in a non transparent bag at work for treating sudden irritation, when it happens. That way I don't have to walk around for hours waiting for it to resolve. Always use ointment afterward.

you are not kidding about the stinging..one night i thought i would try using it try to empty out it was a disaster..soon as i put it in it was stinging like crazy and before i was done i had to evacuate..messy situation..
