If you are in any kind of community with Water Issues (i.e. trying to save water, water saving toilets, et cetera_) your local utility (depends whre you live) may be able to help with this, especially if you can be documented as low income / disabled etc.

A local "st vincent de paul" group (find a catholic church in your zip code) could also help, or maybe even just know a plumber who would donate assistance.

I know these are not exactly the kind of help you are looking for but at 2 am they are the kind of things that come to mind for me!
