On my new pool I asked pool start up guy what the rattle is in the heater and he said it's a spring in the pop off valve. Does everyone else's Pentair 400k btu gas heater do this? It doesn't sound right, and he dismissed it as normal.

- Start date
With limited info - my first bet is U/G, "the spring"

Yes the spring is what he said also. Since this post I called Pentair and he said No it's not suppose to rattle.
PoolguyinCt do you see these spring rattling a common thing, like no problem that's what they do?

Is a problem, needs to be fixed.
Have you run the heater? My bet is a broken internal bypass. Then the barb on the plunger snaps it rattles around till it wallers out a spot big enough to allow it to escape. If you know how to service the thermal regulator it should be clear if the bypass is broken as the plunger will hang up the regulator spring and you'll not be able to pull out the regulator w/o extra effort.

Warranty people came out and and removed the spring with thermostat and replaced cap started pump and it stopped make my noise. Guy said that was normal he tighten the spring on the thermostat and then t made it vibrate a little less.
