Do you remove the vent and fill pipes after the tank is removed?
Yes. We cut the vent and fill pipes and remove them from the outside wall or foundation. If the pipe passed through a concrete wall, we patch the wall with cement. If the pipes passed through an external wooden wall, we fill the holes with silicone to seal the openings. For wood walls, we urge homeowners to hire a carpenter to replace the shingles or siding to seal it permanently.
