Hi, Had geothermal installed in may of this year - everything seems to be working well so far! I was wondering if I perhaps had too much flow, and would be better off, on an efficiency standpoint, to disconnect the second pump. I have a Non Pressurized flow center, with 2x UP26-99U pumps I have 4 wells, parallel, 145ft deep each, 3/4" pipe Ethanol 30% (Geo-Flo) WaterFurnace 5 Series NDV038 When they ran the tests with both pumps, they were actually off the charts and disconnected the second pump to get better readings. Here are the results (Tests were run mid September) HEATING Air: 73.4 in / 98.2 out Fluid: 53.6 in / 46.9 out Pressure: 11.9 in / 8.5 out Flow (derived from pressure): 9 GPM Compressor: 9.7A / 245V COOLING Air: 69.9 in / 50.5 out Fluid: 65.1 in / 73.7 out Pressure: 13.8 in / 10.2 out Flow (derived from pressure): 9 GPM Compressor: 7.5A / 245V Also, if consensus is to disconnect the pump, the wires are daisy-chained. I just disconnect the second pump and put electrical tape around it?
