I have a pump leaking on a Tahitian Utopia, built around 2004. I have a feeling it froze over the winter when we had a power outage. Is it safe to say the pump needs to be replaced? I tried to attach a short video of the leak location, but it doesn't seem to be working. Water is pouring out from the far left side of the pump on the end. How difficult is a pump replacement? Thanks for any help!
