Hi I have recently purchased a 2012 Sundance aspen spa , yes the deal was to good to be true ($700) and filled tub, and found a cracked manifold / elbow. I removed the foam however hard to reach, thinking of putting tub in side and access from bottom . What’s the experts thoughts and any advice ? Everything Else checks out , control board , pumps , heater , etc. thanks for everyone’s time .
