New reservoir to the system

Good morning to all, I have the following concern I have a model that has 6 reservoirs connected. The reservoir (1) pumps water to the reservoir (2). the model runs normally, but now I want to add a seventh reservoir, but at the moment of running I get this error: "Upstream pump elevation [EPU=134.000] > layer 2 for pump 6 Upstream elevation for turning pump on [EONPU=136.000] < layer 2 for pump 6 Upstream elevation for turning pump off [EOFFPU=134.000] < grid top elevation for pump 6" please help me with this doubt. Thank you
