plumbers who can do smoke test? Hi. We have sewer gas smell coming in occasionally. Plumbers don't seem to know what to do. (If they don't catch it in the act of happening, they have nothing to go on.) Does anybody know which plumbing company can do a smoke test? There used to be one, but they removed it from their website.

I'm pretty sure Clean Water Works can do it (http://cwwcanada.com/) doesn't hurt to call and ask.
