100 psi drop overnite

[EXcalibur]

Hi all,

I got a 3.5L CO2 from NA with soleniod over the weekend.

I started using it last night with a timer that was on for only 10hours per day. And I noticed that the psi dropped from 1150 to 1050 psi within that 10hours.

Is it normal for a new setup?

Thanks in advance for the advice.

Hi all,

Forget to add on, the bubble count is about 1-2bps.

Thanks

That is unlikely.

Is that any leakage.

Sometimes there is an initial drop of pressure, especially when the tank is overfilled. After that, the pressure should stay constant around that pressure. Monitor the pressure level for the next few days.

The presure will also vary a little with the ambient temperature.

Hi Excalibur,

Make sure you turn on the nob that release the CO2 at least 360 degree twice. What Chan always advice for new CO2 set is to do a 5 hr leak test. This mean that he will release the gas so that it hit about 1000 psi and shut it off completely again. If after 5 hr, the psi drops, this mean there is a leak somewhere. if everything is OK. you need to turn it back on by turning the nob anti-clock wise 360 degree twice before using it.

When i first start using CO2 set, i got panic when i saw the psi drop to zero within 3 days. I lug the 10+kg 5L set back to NA just to realise that i forgot to turn on the nob.

Hi,

Thanks everyone.

Will go back to try out the suggestions this evening.

the tank could be partially filled. tank are usually not completely filled for transportation from the factory. dangerous and to save cost. so monitor the tank pressure for a few days.

to test for leakage, ensure that the solenoid is off.
turn on main valve (1/2 to 1 turn) to pressurise the regulator. pressure should read 1000+psi for full tank.
turn off main valve, note pressure reading and leave it overnight.
check pressure the next morning. pressure reading should be maintained.
if ok, turn on main valve.

An update.

A leak was detected. After dumping the whole bubble counter into a pail of soapy water, bubbles were seen.

Had stopped the CO2 tank and converted to DIY CO2 for the time being.

Question: if the rubber tube is faulty, can I just substitute with a normal tube ? Or do I need to get a tube that can withstand the pressurized CO2?

Thanks again in advance for the advice.

in moist conditions (like our tanks and surrounding area) CO2 forms carbonic acid.... normal tubes will be corroded after a while..... usually the type made for CO2 system is recommended.

if you can dunk the bubble counter into a pail of water, you do not need soapy water. you'll be able to see the bubble even if you used plain water.
soapy water is used when you cannot afford to use a lot of water to detect a leak.

you can use silicone air tube.

I am using normal tubing, so far no problem.

But as mentioned, if you can, get those black tubing meant for the CO2 system.

But i don't really see a different. Maybe the corrosion will happen after many years.
