Taking into consideration the cost of materials, time involved and labor costs, in most cases the installer is better off cutting out the defective joint, replacing it with new materials and taking greater care in the joining process.
If the joint cannot be cut out, the following repair is somewhat successful. This repair is for leaks only, not cases where pipe has separated from fitting. Leak area should be dry and clean of debris, oil or grease.
1. Apply Weld-On® 810™/811 TM to area to be repaired. Let the adhesive set.
2. Cut a fiberglass mat or tape, providing sufficient coverage/wrap to the leak area. Saturate mat/tape with adhesive.
3. Cover or wrap repair area with saturated mat/tape. Work air bubbles out of the fiberglass mat/tape.
4. Let repaired area cure before pressurizing. Although not a guaranteed fix, this process has proven very successful in most applications.
