high pressure vs low pressure

Hi, i'm about to install a propane quick connect on my trailer, mainly to use my BBQ.
I was wondering if I should only add a line from the existing low pressure circuit and modify my high pressure BBQ to run low pressure or run an all new high pressure line from the tank and leave the BBQ untouch ??

Both ways skin the cat. I guess the two questions you need to decide are what else you might want to run on propane from this line at some point and if you are going to be using your grill anywhere else other than hooked to this camper.

Removing the regulator and modifying the grill for low pressure means you won't be running on the 1 lb canisters any longer or a 20 lb propane tank without putting a regulator back on. Not a problem if you don't intend to do that.

I have a low pressure port on my camper and run a stove off it with no regulator and then run my grill of a propane tree attached to a 20lb tank that has a place to put a high pressure lantern on top and 2-3 high pressure hookups on the sides. Best of both worlds and my camper propane doesn't need to get changed out near as often as the grill propane tank.

welcome to the forum its a great place to get your questions answered. Tap into the low pressure regulated side of the propane system. You can modify your grill with that said there are allot of grills out there designed for what you want to do.

The only difference is whether or not the grill has a built in regulator or not. The actual burners and burner valves are all low pressure, a “high pressure” grill has a built in regulator that takes the high pressure propane source and turns it into low pressure. A low pressure grill has no regulator which means the propane supply needs to be low pressure. That means there needs to be a regulator already between the propane tank and the grill, which there is. It’s at the propane tanks that supply low pressure gas to your trailer.

There is no difference in grilling performance since that is always low pressure.

almost 100% of consumer grills use LOW pressure, but that PRESSURE is always supplied to the grill from a REGULATOR that comes with the grill which converts a 1# or 20# tank's hi-pressure to low pressure...

so by just eliminating the regulator on the grill hose, it works with the low pressure the grill/stove was designed to be used with... not the other way around as you stated in the quote above...

SEE POST #2 here for info on changing to low pressure on a typical grill...

boy it must be summer and camping season. this has come up a lot. i suggest you buy a quick connect fitting (both sides). put the male end on the grill. you may have to unscrew the grill adapter fitting from the grill regulator. put the female side on the existing grill regulator. buy an extension hose with quick connects on both ends.

if you want to use the grill with 1lb bottles connect the existing grill regulator to the grill using the quick connects you installed.

if you want to use the grill with the rv low pressure system hook the extension hose between the quick connects on the grill and on the trailer.

I have my quick connect before the regulator on my 2016 Forester. That way I can use it with any of my outside stoves as I can connect them to the old 1# bottle input on them... as a bonus, when I am boondocking, I can connect a 20# tank to it if I run low on the built in tank. I always need enough propane to get home with the fridge cold. If I use the tank and run out of the gas in it, I can go to any propane place and get it filled, or swap it for a full one.

Used properly, propane is very safe. Mistakes can be disastrous. I'd call around to find a trained, CERTIFIED propane dealer and pay to have him get you set up properly. It's a one time expense if done right the first time.
