If the previous arrangement is not possible, arrangements might be possible whereby the pump dealer can supply a test pump to check the spring. A centrifugal pump works best for this purpose, because the flow from a centrifugal pump can be more easily throttled with a valve on the discharge side of the pump. The valve can be closed until the pump is pumping the exact amount of water the spring yields. The water being pumped can then be measured in buckets or containers of known volume.
