I have 2 30 lb. tanks on my TT. One started hissing when turned on so I switched tanks and no noise. After about a week I switched back to the noisy tank and there was no noise. So a few days later I unhooked from shore power and the fridge switched to gas and the tank started hissing again. What’s with that ?

More info...is it actually leaking propane. Did you do a soapy water test?

Mine hiss (leak) when they're overfull and hot.

Is there a smell of propane and//or your propane alarm is sounfing off? When in the least amount of doubt of a leak shut of the system entirely until it is repaired. .

Noise could be coming from the excess flow hose pigtail.Try physically switches hoses between the tanks.

Regulator noise? Mine makes noise when the flow is heavy, I ignore it.

I has one that was leaking, it ended up being one of the pigtail hoses.
Replaced and has been fine for a while now.

Did you try reversing hoses on the tanks to see if noise moves to other tank?

. Could be that. It’s more of a whistling sound than a hiss.

Would the regulator not make noise on both tanks?

That's what I was thinking also.

Agree. When I run my furnace the regulator sounds like a tea kettle steaming. It only does that when the furnace is running. High volume demand when it whistles. Nothing to worry about.
