You know its not good when I gotta write a follow up post on a praising post about a product. Well, the disillusion about Mighty Putty has been felt. Here are the circumstances:
So there was a tiny crack in this PVC pipe in a garden and I applied some mighty putty to contain the leak. However, it was observed that Mighty Putty would have worked only if the pipe was a drain pipe or something that is not pressurized water. In our case, it didnt take long until the hole leaked again, though at least not spraying out.
We ended up just changing the whole pipe. It would have been cool to try other solutions I saw online, the most interesting being to apply PVC primer and then PVC cement. The primer would effectively melt the PVC to get it ready to actually bond with the PVC cement so its actually sealed.
