Snow

Any paddle pump like a Pony could be used. Just pump it in from and back out to a bucket , Keep adding glycol to the bucket until the right mix.. Work the loops by leaving one open and the others closed. Work each loop one by one..

You want the slab to maintain 42* to melt snow... Since you don't know if the loops are even or properly designed......First set it up so they all have the same flow . Then adjust until you have the same returning temperature by lowering the flow of the warmer loops. From there you will need to adjust the system temperature to maintain a 42* slab on the coldest day...
