Hi, is there a regulation for the distance between soldering on copper pipe? my contractor change water route and also accidentally cut the copper pipe, as a result he had to solder short pieces together. see photo. Will that create weak points during earthquake?
Also, can one use flexible metal connector for tub drainage (shown on photo)
Thank you in advance for your advice!
