Default Why so many regulators?

Can anyone tell me why we/i have a regulator on my LP tank as well as the one located behind the fridge? I was under the impression that the one behind the fridge serviced all of LP devices like the fridge, stove, and furnaces. I have a low pressure problem and am trying to track it down.

Any help would be appreciated.

Thanks to all!

Can you see if there are any high pressure lines coming from the LP tank? Some installations have a single regulator at the tank that services all of the appliances and another high pressure line as noted below. There should be no high pressure lines running any distance as they could result in catastrophic conditions if ruptured. Some Birds I've seen have a short, high pressure line to a quick coupler for a grill. In that case an additional regulator is needed there for anything connected to the quick coupler.

I can't rthink of any reason for two regulators in the same line. That just causes problems.

Early Wanderlodge had 2 regulators one high pressure at the tank and one low pressure somewhere else in your\case behind the fridge
there is high pressure gas under the coach to the fridge regulator not good
If the regulator malfunctions or vents when the fridge is on or has the gas lit you have a big problem
On my 77 fc I removed the regulator Behind the fridge and upgraded the high pressure regulator to a dual stage Regulator at the tank
Took care of any potential BARBECUE situation and never ever had a gas supply problem

I did the same "upgrade" as Stephen. Installed the 2-stage LP regulator at the tank and removed the regulator behind the reefer.

So after you guys removed the high pressure from the regulator behind the refridge and installed the dual regulator at the tank you've now increased the length of low pressure lines to appliances.

My question would be have you operated all the gas devices at once to test your capacity? If it does not cause any issues there then I'm all for removing a regulator located inside my coach! Who does that????

But if untested I'd hold off on the recommendation to modify it.

I was liking it until I saw the hose clamps??? Is that cool, or should there be some sort of compression fitting?

Stephen,

Now mine looks like yours minus the clamps. Anyway thanks for the advice. I installed a two stage at the tank and removed the regulator in the fridge compartment. Now my stove and grill work great. Still working on my Suburbans.

Thanks to all... Another job done!

Soap tested and fine. Barb fitting in hose is extra long and very tight even without the clamp- which is there just to tweak a nudzh now and then. Checked pressure at all appliances with a digital Manometer as well. Adjusted flow on regulator accordingly to maintain 11.0" WC.

Those are Shane's pictures not mine
Now, I trust Shane and his workmanship to install it safely, if he does it. The installation is good
