There is normally not a pump on a water heater. The water is moved through normal water pressure. If you are having problems with getting hot water through, it may be that the pipes are corroding or pinched, slowing the flow. Or the hot water heater itself is leaking.

its when the pressure of the pump is low, this lead to wear impeller, seal leakage , bad pressure plate and insufficient pressure and this can cause engine over heating .
