All of the posts above are good advice, and if you've had your water system in use for a few days look for leaks. Another "possible source is air in the system. When you first fill an RV water system and turn on the pump, all the supply lines are filled with air, It compresses (especially in the hot water tank) and eventually the pump will turn off, but as the HWH heats up, the air will expand, then when you turn on the hot water faucets, there will be two substances (water and air) in the tank, the faucets may sputter a bit occasionally, the pump will run for a time, then in a few minutes, will turn on again to normalize the pressure. As the air bleeds out of the lines (yes, there's air in the low point drains also) the pump will cycle less and less. Air, being "thinner" than water, will bleed out of smaller spaces and can "leak" out of fittings where water would never leak. As it bleeds off, the pump will cycle to repressurize the system. After a few hours to a few days, the cycling will stop. Is it "normal" ??? Well, no, the pump should not cycle, but is it "expected"?? Yes, it's going to happen a few times if the system was completely free of water before use. Once the air is dissipated, the cycling will stop.
