a side observation.....

ARV usually has a built-in check valve; therefore, the customary non-return valve at pump discharge can be done away with.

hope that this saves some effort/money somewhere.

   The installation should be strictly as per vendor specifications. We got    our piping changed after the inspection on one occasion as it was not    conforming to the requirements. The installation is crucial.
