It has been quite a while now, but we’ve noticed that our propane tank makes a funny noise when the Spa heater kicks on. I have a video showing the noise but I could not attach it. The noise doesn’t happen when we first turn on the hot tub heater, its virtually silent. The sound occurs after the heater has been running for a while.
The heater (Pentair MasterTemp 400) works fine and the hottub gets to temp without issue. The sound only happens when the heater is running keeping the water at temp.
I assume this is not normal. Any idea what might be wrong?
Thanks in advance.
