You get HOT flow when on city water connection but no Hot water flow when on pump??
Do you get cold water flow when on pump?
Do you have the 'water valves' set correctly for pump?
City water and pump discharge are connected and feed the same plumbing system.
So if city water works then pump should work also....provided valving is correct and pump works.
Same WH so same Hot water.
More info on what is NOT happening......no hot water, no hot water flow, no hot/cold water flow etc.
Is it time for your medication or mine?
