Hi, thanks for leaving a comment. I reiterate a concept that it is wrong to think that In order to facilitate the starting of a pump it is possible to install a non-return valve downstream of the pump. Instead it would be fine if: installing a non-return valve upstream to prevent emptying when the pump stops. that is, the non-return valve must be installed upstream and not downstream
