There is no problem operating with no check valve but there are some things to keep in mind. First of all, you can get a back flow to cause hot water to enter the cold water lines in some cases, and if the water line should ever rupture or for some reason loose water supply with the water heater operating, the lack of a check valve will mean that the water heater tank will drain and the heat will stay on, thus ruining the tank. The check valve is there as a safety device so it would be wise to in time put one in.
