Can you change how how much the pump is sucking?

You can't change the intensity of the pump action, but you can stop it at any point in manual mode by pressing seal . This would effectively reduce the amount of vacuum in the bag.

You can adjust the duration of the 'suction', therefore allowing you to stop & seal at your discretion. You can choose the manual setting; stopping when the desired amount of air has been removed & "sealing" to stop the vacuuming process. I find the Vacupack Elite Vacuum Sealer a very efficient cryovac machine, using it with confidence - will always seal properly and accomplishes what a good machine should do

You have a automatic and manual mode. In auto mode, when the bag is placed properly, press automatic, give a little push on the lid, and the approximately 24 inches of vacuum, with the heating precess does the job for you. With manual mode, same precess except you press "Pump", when it reaches the vacuum you want, press "Seal", and you're done. You also can set the seal time, depending on what you are doing, with 4 heat zones on that. Good examples are on YouTube, which is what I did myself before purchasing. Just type in the machine model number and make and take you pick. Very good information on YouTube. Hopes this helps you decide. There are lots of models to choose from, and I would definitely get this one model. Also, go the company site, there are plenty video examples to view.

As far as I know, no. The pump runs at the same rate/volume all the time. You can only change the length of TIME the pump runs.

As I could never get mine to work I gave it away. I spent 500$ on a bigger pump but it wouldn't work either. Don't buy this loser, go to Pinch A Penny and buy their vacuum that fits on the return. Cost is less than 200$.

I tried to adjust it too... no luck.... just use less water in the tank and aim it to the side.... the beta will get used to the current :)

You can adjust the output pressure. You can download the manual from generac and see more answers you didn't know to ask.

Any air leak upstream of the pump will kill the draw. The input fitting came loose on mine and allowed air to slip past the o-ring, killing the draw for me at one point. Any obstruction will do the same. Also, if the hose/tube you're using for pickup gets locked against the bottom (like putting your hand to a shop-vac hose), then you'll get obvious results, so be sure to use a stand-off and/or filter screen to help prevent this.

It is not a variable pressure pump setup. You can switch nozzles and vary the output pressure. Somewhat the same result.

That's a long haul... Hope the point is not too deep.... Anyway the pump inlet is 1 1/4 so you'll want to adapt down from 1.5 pipe to 1.25 right near the pump

There are two settings. I made the mistake of having the nozzle on the "suck" instead of the blow. Check it and see :-)

There should be a dial on the pump itself. If not, put a kink in the return hose.

Pump runs the opposite direction than you want. You want something like a powerhead.

I have never seen that done before. I would just switch the hoses if I wanted to reverse the flow instead of switching polarity of the pump.

I will take it down to the grid you see at the bottom of the pump. There it starts sucking air, a little less than an inch.

You can adjust the suction but it adjusts the speed at the same time. I bought this pump as a smaller option for pumping on the go for my twins... I use it exclusively now. I love it!

Yes, you press down and twist - sounds like you might have a non functioning pump which happens more then we like.

The pump is a slight problem and should be improved. you can take top off. no problem!

Yes that is normal! I found that if I turn an adjustment screw that is located just above the pump on that diaphragm it will lower that level it's a small screw with a triangular slot will have to buy a special screwdriver for turning it . I believe turning it in raises the water level turning it out lowered the Water level! But after I played with it I ended up pretty much back in the same spot because if you lower-level too much it sucks air . Then cycles on and Ó ff too much! I had a previous pump for 15 years at my house and it acted the same way. I hope that helps

No. it actually works better the higher it is because it pulls better than it pushes. Moving it to the high point of the pumping cycle takes full advantage of its suction strength.
