Parallel pumps — will it work? Yes. Three things need to happen: 1. Same pump. One discharge pipe means one pressure. The weaker pump can't beat it, so its check valve never opens — motor running, nothing delivered, water heating inside until the seal fails. 2. Resize the suction pipe. It was sized for one pump. Two pumps pulling through it means higher velocity, higher friction, lower NPSH available — cavitation, and everyone blames the pump. 3. One check valve per pump. Not one on the header.
