Give your below ground water tank access from the surface with these accessories. Our store carries manhole extensions, which attach to the top opening of the tank to provide accessibility from the surface. When your container is being installed and you plan to add a manhole extension, make sure to add it before the area is backfilled. All manhole extensions attach to a tank with screws and a gasket, which come with the product. Our store carries these in sizes from six by 20 square inches to 24 by 20 square inches. When adding the product, make sure the fit is exact before backfilling around the tank.
