My heat exchanger cracked in my aquacal over the winter. I opened the pool myself this year and saw the water gushing after I got the water running. I spoke with another pool store in my area and told them what had happened and he was quite surprised, stating that this is a liability for him. I spoke with Aquacal and they asked me if I winterized my heat pump or if I had a pool service do it. Do I contact my old pool service about this issue and try to get them to foot the bill for this based on the other pool store's comments? I'm new to having a pool (going on 2nd year) and I'm not sure what I should expect from mother nature and what I should expect from a pool service.
