We laid new HDPE sewer lines for a home in Sde Boaz yesterday.
Most plumbers still use PVC with male/female socket connections in Israel. However, most new buildings and high-end construction has moved over to High Density Polyethylene --HDPE -- pipes. The advantage? Most of the connections are butt-welded or electro-fused. That means less chance of leaks and less places for nasty, and costly, root intrusions.
