1. Reasons for water leakage at the interface of the ppr pipe:

If the ppr pipe has just been hot-melt welded and leaked during the pressure test, the possible reason is that the construction master did not have a good hot-melt connection. Then the raw material of the ppr pipe is not good, and the possibility of water leakage caused by insufficient hot-melt connection is greater.

2. How to deal with water leakage at the interface of the ppr pipe:

It is not recommended for everyone to repair welding for leakage of hot-melt joints of Ppr pipes:

Repair welding is that we do not replace the leaking parts, but take repair welding on the leaking parts. This method is simple but not reliable.

(1) Leaky repair welding only repairs the surface of the leaky joint. The material we use for repair welding is to melt the surface of the material for repair, and the melting process will cause the surface of the material to melt and solidify, and the cracks in the butt joint cannot be repaired.

(2) The pressure bearing capacity of the repaired pipe is poor

It is suggested here that if there is water leakage at the hot-melt interface of the ppr pipe, be sure to cut off the leaking part, re-use the ppr pipe ancient, and heat-fuse the leaking parts together.
