How to clean and maintain PPR pipe unions?

The cleaning and maintenance of PPR pipe unions require continuous attention and meticulous operation to ensure their long-term normal use and prevent potential problems. Check the sealing of PPR pipe unions regularly. After long-term use, the unions may become loose or seal poorly due to water pressure, temperature changes or external forces. Therefore, all connections should be checked regularly to ensure that there are no leaks, seepage or cracks. If water leaks or damage are found, the relevant water source must be turned off immediately for repair or replacement to avoid greater damage.
For cleaning, warm water and neutral detergent are the best choice. Avoid using detergents containing chlorine, acid or strong alkaline ingredients, as these chemical ingredients may corrode PPR pipe unions and reduce their performance. For daily cleaning, you can use a soft cloth, sponge or brush to dip in the cleaning solution and gently wipe the surface of the union to remove dust, oil, and scale. If the scale is stubborn, you can use a mild descaling agent, but be sure to make sure that the detergent is suitable for PPR material and use it strictly according to the instructions to avoid excessive or long-term use that may cause damage to the union.
For some old or long-uncleaned PPR pipe unions, the accumulated dirt may be difficult to remove. At this time, you can consider using professional pipe cleaners, which are specially used to remove the internal scale of the pipe and will not corrode the PPR material. When using pipe cleaners, you should follow the instructions in the product manual to ensure that the surface of the union is fully cleaned and rinsed with plenty of water after cleaning.
In terms of daily maintenance, it is very important to ensure that the connection parts of the unions are not loose and leaking. Check the unions of PPR pipe unions regularly to see if they are tight. Long-term use or pressure fluctuations in the water flow may cause the unions to loosen partially. Therefore, use a suitable wrench to check the unions at regular intervals and re-tighten them if necessary. Especially when adding new loads or modifying the pipeline system, pay special attention to the sealing of the unions .
Be careful to prevent the unions from being exposed to ultraviolet rays for a long time. Although PPR materials have certain UV resistance, long-term exposure to strong sunlight will still cause the material to age, become brittle, and even break. For this reason, it is recommended to partially shield the PPR pipe unions or apply an anti-UV protective layer, especially when installed outdoors or in direct sunlight. Consider using pipe protective sleeves or special coatings for additional protection of the unions.
As for the service life of PPR pipe unions, PPR materials usually have a long service life, but if they are not maintained for a long time, impurities and scale in the pipes will affect the smooth flow of water, thereby affecting the performance and service life of the unions. Therefore, it is recommended to conduct regular inspections and maintenance, remove scale, dust and debris in time, and keep the pipes unobstructed. The ambient temperature of the pipe should also be kept within an appropriate range. Too high or too low a temperature may affect the sealing and durability of the PPR pipe unions.
