So we're being told all over the place that PVC glue isn't potable, however how the heck do you make one then if you can't seal it with the glue? I asked the store about all purpose PVC glue and he said it doesn't exist and that you need special glue for each different kind of PVC pipe. Then my cousin (who's husband is a plumber) said that no kind of PVC glue is potable. So...what am I going to do? Others have said they've used it without issue, but I really, really don't want to hurt my girls. What to do?
