What is your pressure reading after 30 seconds? 40 seconds? My new VP112 gets 22.5 in 30 and only 23.2 in 40, is it broken?

with machine empty 15"=24, 20"=26, 25"=27, 30"=27.5, 40"=28, 50"=28...make sure seals areas are clean, clean, clean.

It seems as though your numbers are lower than what I see. James comment about your altitude is important, but so is what you are trying to bag. If you are trying to bag some food that is hot (or even warm), it can reach "boiling" before you get to the level of vacuum you desire. Ideally any food being bagged should be cold to prevent this from happening.

I get 27.5 after 30 secs. But keep in mind that that maximum is whatever you barometric pressure is so if you live in Boulder the max at this time (4:15 pm, Pacific time, 8/24/2014) your max would be 24.6). My current max is 29.8. I did a "dry" run, nothing but the plastic filler sheets in the chamber. If you have water in the chamber, you will never be able to reach the maximum, regardless of the system you are using.Are you "helping" by holding down the two sides until the pressure starts to drop? It helps.

the top surface is important as it is injection molded and sometimes there is flash from the mold. feel the top surface and see if there any burrs there, if there are you can use a piece of sandpaper or one on the little fingernail thingies to make it smooth, it does not take much to loose vacuum. Put a bit of cooking oil on the seal and try it.The only problem i have had with mine is keeping the screws tight on the right side.

That happened to me a couple of times. I found that if you simply press down lightly on the front when you press start it'll create that vacuum seal.

I ran mine at 90 psi with a 150psi tank. Fired fine until tank pressure got below 40psi.

Not normal. It should only click on when pressure decreases to on pressure set point. It must be losing pressure somewhere. Bad gauge maybe ?

Thx for all the answers to my question "Can you tell me what the max flow rating is on this valve in GPM? Thx." For the record it looks like Christine was the closest correct response overall. Valterra finally responded and said the valve is calculated for 14-15 gpm at the preset 45 psi. This sounds to me like a very high fps calc but at Christina pointed out this is under optimum conditions so I say take it with a grain of salt. Most ½ valves will be limited in real world to app 7-8 gpm and 5/8 to app 10-12 gpm IMO. A good comparison would be with Watts regulators also. Thx again to all.

Hello Carolyn...I'm not sure I understand what codes your looking for. I see the classification table,would those be the particulars your looking for?They seem to explain at what pressures Stage 1,Stage 2,Stage 3,normal and optimal are. That indicator is on the side of your main reading. The bar shows at what stage your at.

What kind of meter are you using. I have gas meter for measuring inches of water column. If that's what you have then No everything should read 0 if there is no gas pressure

I returned the one I purchased for the same reason it would not hold pressure, Amazon refunded me the purchased price. Review the return policy Amazon even paid for the return packaging.

this has not been a problem for me. Are you zeroing it out? Has this been a problem from the first for you? Mine has always settled in, but there are occassions when it does kind of go back and forth between for example 27g and 28 g if you are really on the edge of a little more than 27g and a little less than 28g. I hope this is helpful. If yours is bouncing all over then perhaps you have a defective one. I hope this is helpful. Good Luck.

It all depends on the temperature and line length. I had to change my lines to 10' because the one that came were too short but at 38 degrees with 10' lines I set my pressure to 12-13 psi.

&lt;If the pump is running longer then 90 sec. you may have to change the pressure line ( .25 white plastic line to the pressure switch) to a different location. &lt;i bought a the same pump and it ran to long to build up pressure so I put it closer to the tank.

I am doing 10 GPM. I am sure it can take more since I do not notice a drop in pressure before the unit was installed and after the unit was installed. What is your reason for buying the unit?

I THINK the longer automatic pressure release time helps...and in reading found that adding 5 minutes to cooking time was helpful. you can also add some cooking time after you check for doneness with a thermometer. I like mine a lot, nut it is the first one I ever used and have no prior experience to compare it with.

The gauge will not read pressure while your adding air. When you release the lever it should read the tire pressure. I'm a professional mechanic & have used mine on cars & heavy duty trucks. Pressures ranging from 30-120psi. The gauge has always been very accurate. Milton is at the top for quality for many years. Hope this helps.

the pressure switch is adjustable, the one I order was preset at 40-60 psi......... 40 being the cut-in and 60 being the cut-out........... look for one with the pressure setting you want; otherwise you will have to read directions and set it either higher or lower yourself.......... not hard to do. hope this helps

I've put a cartridge in mine, fired it a couple of times, set it down for weeks, picked it back up and it is fine. No apparent loss of pressure. Michael's answer of around 70 shots is probably pretty accurate. I haven't counted but you can definitely tell when the cartridge needs changing. You can hear when the pellet doesn't have the same punch behind it and the pellets start hitting low. I think it may be more like 50 shots? I know that when I do notice the cartridge needs changing, I unscrew the cap and only get a short "phisst" and that is it. It's empty. It uses all the CO2 effectively.

Mine was set to cut in at 40psi at factory and I installed a pressure valve in the pump outlet line and set it for 60psi but it can go a little higher if you think your water lines can hold the pressure.

if it's working right, it should pressurize it less than a minute. I've had major issues with two of these pumps losing the ability to come to pressure. Haven't had much satisfaction with repair or customer service. I would advise against this pump if you haven't already purchased one.
