Zurn Plumbing Service uses a sewer pipe liner which is a flexible, inflatable tube that is inserted into an existing damaged pipe. The tube is then inflated, filling the space between the liner and the damaged pipe. Once the liner has cured, it forms a permanent, watertight barrier within the damaged pipe, restoring it to its original condition. Zurn Plumbing Service’s this method is ideal for repairing small cracks and holes in the pipe without having to dig up the entire pipe.
