The versatile MULTIBLOCK® underdrain has been installed in concrete and steel gravity filters for a number of applications. Packaged treatment units as well as large cluster filters have benefited from the design. It readily combines with the unique MULTIWASH® baffle to provide unlimited air-water backwashing. Your old clay tile underdrains are ideal candidates for replacement with MULTIBLOCK underdrains which are NSF Standard 61 approved.
