Gaslow bottle query

[monzer]

Hi all. I am wanting to know if the single Gaslow 11kg bottle I have in my locker can be used as part of a 2 bottle system. Looking at the way Gaslow say a 2 bottle system should be set up I am wondering if this bottle is suitable. It doesn't seem to have enough outlets for all that is needed.

2 pics of my current bottle attached:

yes you can, see this picture...
i have the lower arrangement, one refillable and a second Spanish Repsol bottle.
you need the set up in the upper arrangement....
HOWEVER, both these use a bulkhead regulator with switch over.....one reg serving both bottles...
i see from your picture you have an 'on bottle' regulator...you would need the same on bottle regulator for the additional bottle...
IMV much better to ditch that and get a change over bulkhead reg and make a nice neat job of it....on bottle regs take up space and make the curving of hose a bit more tricky.
good luck.

Cheers for the info bolero boy

Yes the original Gaslow bottle does seem to have a regulator on it but the hoses from both bottles go in to a T-piece bulkhead regulator screwed on to the roof of the gas locker.

At least I think that's what it is.

The guy from where I bought the 2nd bottle kit says I need to disconnect the filler input to the original bottle and use that to fill from my new bottle. Obviously this means my new bottle will now be the one connected to the outside fill point.

I'm getting there but still think I am a few of the correct hoses short and not sure if I need the changeover head that was supplied with 2nd bottle kit.

monzer, the photo shows the two bottle hoses going into a Truma changeover valve which is sitting above a Truma bukhead regulator....they are easy for someone to confuse.
the output of the changeover valve goes into regulator and then on into the vans gas system.

i hasten to add, this is NOT my system (web piccy) and those hoses are too short and tight. its often better to connect slightly longer hoses from (say) the right hand bottle to the left hand changeover input....and vice versa.
this means the hoses are not under tension nor risk getting kinked.

You can 'daisy-chain as many bottles together as you like (but two is as many as you're likely to find on a motorhome. Any extra "intermediate" bottles need two connections in the top. One is from the LPG filler and the other is to pass to the next bottle. Yours is a standard "end-of-chain" bottle with only one connector (no "pass-on"). You just need an extra length of filler hose if you add an extra bottle, to fit between the two bottles.
You would need to manually swap your regulator from one bottle to the other when changing bottles but it would be better to chuck that and replace it with an auto changeover bulkhead regulator, with new pipes from that to connect to each bottle.

Or add a t-piece.

True.
But, when buying an additional bottle, get one with the T already in place.

I got a second hand No1 bottle cheap or else I would have done.

Thanks guys I've been faffing about with it all day. I think the bulkhead regulator that came fitted in my vans gas locker was quite old and the fittings were a different size to my new hoses.

I bought a new bulkhead regulator and fitted my gaslow manual changeover head to that. It was then easy to fit the two outlet hoses from each bottle on to the changeover head.

One thing I am pretty disappointed about is that I decided to splash out on the gaslow wave bluetooth guage but it only connects in to one bottle so not very handy for a 2 bottle system.

I also had a few wires connected up to the old system. I know one was the truma regulator heater but the other one went in to the back of a small gauge which had 1 bar printed on it. Not sure what that is but it's not connected anymore and kinda just has to hang there for now.

Heating's on and van is all cosy so looks like it's all working. If I do perish in a large explosion over night tell my mum I was a good lad and a joy to have around the forum

Get the soapy water out, test all joints. Sleep safe good lad....

Well it's over a month since this thread started and still finding it hard to get used to the 2 bottle system.

I have 2 11kg bottles in to a manual changeover valve then in to the regulator.

After installation I went to the garage and filled up with gas. It took about 30 litres before slowing right down so I released the fill button. Checked the bluetooth gauge and it said both bottles were full which would have been impossible with just 30 litres.

Decide the wave gauge was faulty and left it at that. I had turned bottle 2 off and bottle 1 on. Everything working fine for about a day before boiler went out and wouldn't ignite. Wave gauge saying bottle 1 is at 75% but no gas coming out of it.

Switched to bottle 2 and everything working fine for about the normal time it takes for a bottle to empty. After bottle 2 was empty I unscrewed the hose on bottle 1 and opened the valve. Plenty gas in it so maybe 75% was right enough. Connected it back up and plenty gas coming out at cooker. Parked up again and boiler wouldn't light and no gas at cooker. Went back to locker and opened the valve of the empty bottle 2. Everything working fine again.

So....

Did bottle 1 have some kind of air lock that I have released? I have read that new bottles can sometimes stick like that.

And I can only presume that bottle 1 is now filling bottle 2 then bottle 2 is feeding the regulator as I couldn't get gas in the van with bottle 2 closed even though I am 99% sure it is empty.

Am I missing something obvious with the manual changeover valve?

No both bottles fill at the same time as seen in diagram above in post 2 the gas comes in to a T piece so fills both bottles

But the thing is, my bottle 2 is empty. Bottle 1 has gas in it. I turned on bottle 1 and turned off bottle 2 and the gas wasn't flowing in to the van. I then turned on bottle 2 (which was empty) and the gas is flowing in.

So I can only presume that the gas in bottle 1 is flowing through the filler hose in to bottle 2.

 

[denisejoe]

The bottle you had is bottle 2 the new one is now bottle 1
did you change over the manual changeover valve and are both bottles turned on?

did you connect fron the filler to the top connection on new bottle and the lower connection goes to the second bottle as there is built in non return valves

 

[monzer]

The manual change over valve is basically just a T-piece. There is no switch to change over from 1 bottle to the other, as far as I know You just turn the empty bottle off and the full one on.

I really ain't getting it. All I know is the heating is on and working fine but I would like to understand what exactly is happening.

You can just leave both bottles turned on even when filling

Ah, now we could be on to something.

I went with this:

Their filler hose goes to the lower connection

That cylinder has been modified ( someone has ground off the shroud , not safe to use it needs scrapping

Autogas told me to make sure BOTH bottles were turned off when filling and to vary which bottle is used first by turning one off. The reason being the tendency to overfill the system because the same bottle is used all the time leaving one full, resulting in an escape of gas from the pressure release valve particularly in hot weather

It's ok I'm going to weld a new one on.

 

[denisejoe]

Not sure that’s a good idea

 

[tonyidle]

Having no shroud is irrelevant. It does make for better hose runs without it which is probably why it was removed.

In my world it’s been modified so it’s scrap , as the cylinder was heat treated during manufacturing that’s now been potentially compromised.
As a company we don’t take risks and would advise anyone with a similar cylinder to scrap it .
Call Gaslow for a definitive answer but I know exactly what they will say

 

[two]

Don't bottles have an expiry date stamped or printed on them?
Maybe they have been erased, but I imagine it will have passed.

Looks to me like it was cut with a disc above the weld. If it has been cut using ox-acetylene then I agree entirely.

It wasn't me that took it off but I presume it was indeed done to make a bit of space. I also agree that whoever did do it wouldn't have been silly enough to do it with the gas torch.

Later Gaslow bottles don't have the shroud. Having one only makes decent pipe runs close to impossible. They're needed on portable bottles to prevent valve damage when handled and transported. They're not need on bottle-shaped tanks that stay where they're put.

 

[rb62]

I hate to say it but in my opinion that has been cut off with an gas torch,hence the paint removal and spatter on the tank and trapped where it has been cut off.If it had been cut with a grinder, the cut material would travel away from the tank.

 

[Wagoneer]

As far as I know, Gaslow stopped using shrouds about 2005. In which case, a bottle which originally had a shroud would be over 15 years old and should really be binned.
