Anybody have some extra waterbed style caps/plugs lying around they don't need, or know where to pick some up? Somehow misplaced a bunch of them from some old bags I'd like to use again and can't find them locally.
get drain plugs with a metal ring from the plumbing department of any small or large hardware store. The coast about $1, are tapered more than standard fat sac plugs and you will no longer need a cap.
I took a cap to walmart and unscrewed lids on various bottles and found that Pine Sole bottles have the same size cap. Just take a cap to Walmart and see what fits for the cheapest price. My wife still has cap less bottles of Pine Sol under the kitchen sink.
