Is it OK to run with both cylinders open?

I have 2x11kg gaslow cylinders with inbuilt crash sensors. I don't have auto-changeover.

As I get towards the bottom of the 1st bottle is it OK to open the 2nd as well, so I won't run out during the night?

I've always done this in the past but for some reason I'm now questioning that.

when I had a 2 cylinder system I used to open both valves at the same time as I didn't have auto-changeover either - never found this a problem.

and the Lord said unto John "come forth and receive eternal life". but John came fifth and won a toaster........

If you have a concern why not just turn on the second bottle and turn off the first?

I just let one run out and then open the other, not worried about running out unless the cooker/oven is in use, it's a two minute job to turn on the 2nd cylinder.


but in reality, I top up when I see a pump so rarely get to the second cylinder.

Thanks all.

Basically I'm a lazy so-and-so and got the new system so I wouldn't always have to go into the garage to turn on/off when I left the MH, or parked up at night/left in the morning. I know, more money than sense, but I'm enjoying it!

And as for going out in the middle of the night.... probably in the wet....

Also, I have 2 big bottles so I don't have to pull in for gas as often - always seems a waste of time!

That's encouraging that I'm not the only one who opens both.

I wonder what Gaslow's advice would be.



So what do you do when they both run out at the same time??


It was recommended to me that I use one cylinder until it was empty and then change to the second cylinder, with the gauge. Fill up at the next available opportunity, which fills both tanks.



You could of course put a gauge on both cylinders. Important to note the gauge only registers "getting empty" when it's going through the last half of the tank. So it stays on green (full) for a long time, then suddenly and quickly heads towards the empty mark.

I do have a guage on each Viv. I've never let a cylinder run out - think I was trying to avoid gunge in the whatsitsname. When I think the 1st is getting low I'd have opened the 2nd either as well as, or instead of. Then after a few days I'd start looking for LPG.

Good point about asking Gaslow.

I did ask Gaslow and Louise, who's been very helpful in the past, phoned me today to say they recommend just having one open at a time. Nothing to do with safety, but your 2 bottles then go down in tandem so you could end up running out - I think is what she was saying. She also said there's no problem with gunge in the regulator - that was only when rubber hoses were used. So I can afford to run them a lot lower than I do at present - well, the 1st one anyway!

Never had a problem with gunge (touch wood). But system has stainless steel hoses.

That's right Viv but I was still working with fears from the legacy system.
