I recently built a new house with a geothermal heat pump. We had a 140 foot well with a 1.5 HP continuous feed submersible pump. Everything is great unless the heat pump is running and I'm trying to water my lawn. At that point, my sprinklers barely work. I can tell there is a pressure drop if I am showering when the heat pump is on, but it is not very noticeable. I really do not want to upsize the current pump. I am thinking about digging my own shallow well and installing a sprinkler system in the future, but was wondering if I could add a second submersible pumps in the current well and isolate the heat pump so that it is the only thing on the current pump. Can a second pump be installed above the original pump? Can I add a second pitless adapter?
