I Fear the EOTD...What do you do to prevent it?


I am new to pressurized and am weighing the options. How much is a LPR and what brand would you recommend?

You lost me with "LPR". I have advice re: how to avoid EOTD (end of tank dump), but I'll reserve my [possibly unneeded] information until I learn what LPR stands for.

simply look at the gauge at every water change or every other. My tank lasts me around 6 months so im not that worried about it till around 5 months or so.

Ah.. In that case, I may be useful. Having owned Milwaukee and JBJ regs, I will offer my experience. In short, JBJ regs allow little to know EOTD, and depending on the circumstances, Milwaukees can allow a large EOTD. This is because Milwaukee regs come with a low-pressure valve (besides the needle valve). JBJ's have a set low pressure reg - it can not be adjusted. If you set the low pressure valve to a very low rate on a Milwaukee, it will be impacted greatly by an EOTD. And, if you set the low pressure valve to a very high rate, it will NOT be as heavily impacted by the EOTD. However, this makes the needle valve harder to adjust.

Basically, because JBJ's do not have an adjustable low pressure valve, they seem to be more stable and less prone to human error.

Some folks have had problems with JBJ's. That is a bummer. But, mine have worked flawlessly for over 3 years and numerous tank changes. I've never used a controller, and I've never had an EOTD with any of my JBJ regs. Sometimes I don't even get around to changing the reg until the tank has completely run out of gas.

My one Milwaukee reg, I need to keep an eye on . It has gassed the 50g tank it feeds on more than one occasion.

Just to add another tidbit...

I have a Milwaukee all-in-one regulator, and from the point when it starts to show a reduction in pressure to completely empty it is two, maybe 3 weeks. So as you get towards the end of the tank (for me ~one year) I start to do weekly checks. Hasn't failed me once.

You can get a Clippard LPR from Rex Grigg for $20 that you attach on to your regulator. If you describe your set up he'll tell you what adaptors you need to attach it. He'll have that as well.

Ok, let me see if I understand this. If the low side pressure is set low--then there is higher risk of a EOTD, correct? And if the Low side is set High--there is little or no risk of EOTD, correct?

Many people recommend setting the low side at 10-20psi. I have found better results at 30+psi (especially on multi-output setups). I have yet to experience an EOTD that I am aware of....and I run the tanks to Empty!

So, is it looking like Higher psi on the low side eliminates or reduces the EOTD?

Thanx!

Correct. By setting the Low pressue guage to a higher pressure, it insures that when the EOTD kicks in (even higher pressure), the reg doesn't allow it to blow through. Basically, it comes down to this rule: use your needle valve (as much as possible) to regulate CO2 gas flow, NOT the Low-pressure knob. AI high pressure setting on the Low-pressure guage, and a tight needle valve make for a more stable setup when the EOTD comes.

Cool, Thanx. I will certainly keep this in mind. It helps explain why I am not aware of any EOTDs on my setups.

Personally, I've found this to be true all the way through the tank. I had the same problem many others complain of---set the NV/Bps and then come back later and there's No bubbles or its Greatly reduced. I found that by Jacking up the low-side pressure---I could set the NV and forget about it.

My Rex rig runs at 32psi and the Azoo at 40psi.







Many Thanx!
