How and Where to Install a Wall Seal
Installing the Fernco Moulded Wall Seal involves:
Fitting the Seal: Press the wall seal into the hole in the concrete structure. Avoid using lubricant on the seal.
Preparing the Pipe: Chamfer the edge of the connecting pipe and apply lubricant to the pipe, not the seal.
Pipe Insertion: Centre and push the pipe into the seal, ensuring that the pipe end is flush with the inner wall of the structure.
