Copper waterlines can leak due to erosion, improper solders, and time. When they originally installed the waterlines, the house wasn’t settled yet. Over time as the house settles, it puts pressure on the waterlines and can cause splits in the pipe.
When Poly-B (Polybutylene) first came out between the 70’s and 90’s, the installers and manufacturers didn’t know the effects that UV rays had on the pipe. If it was stored in the sun or even in the sun too long, it affected its durability. Over the long run the pipe would start to develop leaks way earlier than expected. It causes so many leaks that insurance companies won’t insure a home that has Poly-B in it, and they require a plumber to replace it all.
Leaking waterlines aren’t just a hassle to fix, they cause lots of unnecessary damage to your home. If you have Poly-B pipe, and notice a slow drip in your copper waterlines, have us come evaluate the situation, and if recommended, replace your waterlines.
