I opened the pool yesterday with hardly any issues. When I started the pump, water started leaking out of a crack near the pressure gauge in the multiport. It isn't leaking too badly so it's not a big deal. I plan to try epoxy to stop the leak first but I was searching for a new replacement in case that doesn't work. I tried searching for what I have (SP714A). The age is unknown but I can read the model number clearly so I'm confident that's what I have. When I search for it I only get returns for the SP714T. Is that just a newer version or is the "T" significantly different than the "A"? They look identical from the pictures. Thanks!
