When you can't get plumbers out or afford them, damsels in distress can usually get very good success by calling the fire department's non-emergency (it may be non-emergency dispatch if they dispatch both police and fire in your municipality) number and telling them you have gushing water and need a "public assist." On slow nights, they'll be more than happy to help you get plumbing stuff dealt with quickly and for no charge. It's a courtesy they provide like getting kitties down out of trees. Sunday nights at the fire department are generally very slow. It's worth a try!
