So Im at a warehouse and a huge galvanized waterline with too few supports started to crack and leak at a joint. A plumber tried to repair it using some type of clamp on fitting/union. Long story short it didnt work and popped off when the water pressure got up.
My question is, are these “sharkbite” or clamp on fixes ok to use or do these kinds of repairs raise red flags right away? Do you need to re-thread and replace or are repair “units” ok to use in scenarios like these?
