- Apply another layer of the first PVC and cement mortar to create a waterproof seal.
NOTE: Make sure the pipe is completely dry before applying cement to ensure a stronger bond.
Cracked Pipes
Problems:
PVC pipes can crack due to external pressure, freezing temperatures or severe damage. A broken pipe can cause serious water damage and flooding.
Fix:
- Cut out the damaged area with a pipe cutter.
- Measure the gap and replace it with a new PVC pipe, making sure it fits properly.
- Use PVC joints on both ends, use primer and cement mortar for proper sealing.
Clogged Pipes
Problems:
Blockages can be caused by dirt, hair or build-up in the pipe, reducing water flow and supplemental construction.
Fix:
- Use a pipe wrench or a screwdriver to remove the tissues.
- If the stain is still there, use a PVC safe chemical cleaner to break up the stain.

If the pipe is already hanging, move it to secure the new support.
Tree Root Intrusion
Problems:
Nearby tree roots can penetrate PVC pipes, especially sewer lines , the pipe will crack and break

Apply an anti-aging chemical to prevent further growth.
In extreme cases, it may be necessary to replace the damaged section of pipe and install a root barrier to protect the pipe in the future.
Loose Pipe Design
Problems:
PVC fittings can loosen over time due to thermal expansion, water pressure, or improper installation, it may be damaged or improperly installed. Run
Fix:

Problems:
PVC pipes can “water hammer”, which occurs when water suddenly stops or changes its direction. cried. noises. .
Fix:
- Install a water hammer clamp to absorb shock and reduce noise.

- Adjust the water pressure if it is too high as this will help the problem.
Pipe Freezing
Problems:
In cold weather the water inside PVC pipes freezes, the expansion of ice causes them to crack and or broken. the pipe.
Fix:
Insulate exposed PVC pipes with foam pipe insulation.
For frozen pipes, use a hair dryer or heat gun to gently melt the ice.
If the pipe is broken, replace the broken part according to the steps for broken pipes.
Chemical Corrosion
Problems:
Although PVC is resistant to many chemicals, prolonged exposure to some strong chemicals can cause it to corrode and weaken. the pipe breaks. .
Fix:
- Identify the source of the chemical exposure and eliminate it.
- Replace the corroded part with a new PVC pipe, suitable for the chemicals used in the system.
- Consider using chemical resistant pipes or covers for exposed areas.
