Did you know that...if you order a tapered rotor seal and attempt to install it into a straight sided casting, the seal will be cut. If you install a straight seal in a tapered casting, the valve will leak. The tapered seal can be identified by a mark on each of the vertical legs signifying the top of the seal. Since the straight seals are not directional, they have no marks on the vertical legs. The tapered seal P/N is 071720. The straight seal P/N is 071719, which we no longer manufacture. Both 2000/4000 series filters with backwash now use the same Noryl rotor and the tapered seal. The product number for the rotor and seal assembly P/N is 073370. Tapered castings have a letter "T" stamped into the underside of the middle pump port. Don't confuse this with a letter "T" in felt pen, which means the assembly has been pressure tested.
