Identify the source of the leak
PPR Fittings can leak from several points. Check the fusion joint first. Check the threaded connection if present. Example: a leak at a fused elbow.
Turn off the water supply
Shut off the main water valve. Drain the pipe section completely. Open a nearby faucet to release pressure. PPR Fittings must be repaired on a dry line.
Assess the damage
Determine if the fitting can be repaired. Small leaks at threaded joints may be tightened. Leaks at fusion joints require replacement. Example: a cracked fitting must be replaced.
Repairing threaded connections
Threaded PPR Fittings may leak at the threads. Tighten the connection slightly. If it still leaks, remove and re-apply sealant. Example: a threaded adapter to a valve.
Cutting out the damaged fitting
For fusion joint leaks, cut out the fitting. Use a pipe cutter for clean cuts. Remove the damaged section. PPR Fittings fusion joints cannot be repaired.
Installing a new fitting
Install a new PPR Fitting using heat fusion. Follow the correct heating times. Join the pipe and fitting. Example: a new elbow for a damaged one.
Using a repair coupling
A repair coupling can join two fixed pipe ends. It has no internal stop. This allows it to slide over the pipes. PPR Fittings repair couplings are useful for tight spaces.
Example: repairing a fused elbow
A fused elbow leaks. The plumber cuts it out. He installs a new elbow with a repair coupling. Example: a successful repair.
Example: repairing a threaded adapter
A threaded adapter leaks. The plumber tightens it. It still leaks, so he re-applies sealant. Example: a simple repair.
Example: repairing a cracked fitting
A fitting is cracked from freezing. The plumber cuts it out. He installs a new fitting. Example: a permanent repair.
Pressure testing after repair
Pressurize the system after repair. Check for leaks at the new joint. Hold pressure for 15-30 minutes. PPR Fittings repairs should be tested.
Final repair summary
PPR Fittings leaks require proper repair. Threaded joints may be tightened. Fusion joints must be replaced. Cut out the damaged fitting. Install a new one with heat fusion. Use a repair coupling if needed. Test the system after repair. PPR Fittings are reliable when properly repaired. Example: follow these steps for a successful repair.
