Aquatherm pipe is very durable, but may be susceptible to damage under extenuating circumstances. In cases where the pipe is cracked due to stress, the affected portion can be cut and discarded.
If the pipe has been punctured, a repair plug along with the appropriate welding head can be used to seal a hole. Both ends of the repair plug may be used, with ¼" on one side and 7/16" on the other. If the pipe has a hole too large for a repair plug, an outlet fitting can be used and capped off.
