I agree that it's pretty convenient to use the bathtub. It's the only place that I've ever done soil flushes. And I keep a fine-mesh sieve on top of the drain when doing this. It works very well at catching anything I don't want going down the drain and clogging it up.

Although, I am intrigued by Dutch Pimp's method...and am going to be giving this a try in the future. Thanks for sharing that DP! :thumbsup:
