I am surprised to hear the Pat the Plumber is still in business. There is no reason to do this type of test on a tub in a residential home. If the tub doesn`t hold water just adjust the cable, or clean out under the pop-up. I bet there was no problem with the waste and overflow holding water. A test kit to do this for commerical applications cost $27.00. I have been a plumber (i hate to say) for 40 years, and have had my own business for 32 years, I have never heard of anyone ever doing this type of test on a residential tub. It would have been alot cheaper to just replace the waste and overflow. It has been my experience that most waste and overflow units on residential tubs last around 20 years.
I am happy to say that I just sold my Plumbing business in NJ and will be living full time in the Villages in a couple of weeks. If anyone needs plumbing advice feel free to contact me anytime, but I did hang up the tools....
