When do PPR check valves need to be replaced

Determining whether the PPR check valve needs to be replaced needs to consider a number of aspects, including the following:

Periodic inspection

Check the PPR check valves regularly. Observe whether there is obvious damage to its appearance, whether the switch of the valve is flexible, and whether the sealing performance is good. If abnormal conditions are found, maintenance or replacement should be carried out in time.

Service life

Generally speaking, the service life of the PPR check valve is about 10 years. If your PPR check valve is more than 10 years old, it is recommended to consider replacing it with a new valve.

Performance index

If the sealing performance of the PPR check valve is reduced, the switch is not flexible or the corrosion resistance is poor, it should be replaced in time. In addition, if fluid leakage, dielectric backflow, or other performance problems are found, the valve should also be replaced.

Maintenance cost

If the maintenance cost is too high, or even exceeds the price of the new valve, it is recommended to replace the new valve.

Safety consideration

If the PPR check valve is seriously malfunctioned or damaged, it can have an impact on the entire piping system and even cause safety issues. In this case, a new valve should be replaced immediately.

To sum up, determining whether the PPR check valves need to be replaced is a comprehensive process. When the problem is found during the inspection, it should be repaired or replaced in time, and it should also be judged according to the service life and performance indicators. If the maintenance cost is too high or there are safety problems, the new valve should be replaced in time.
