Does it require much air pressure to operate. I need some to release slight vacuum (air in) to break a siphon.

You do not use air to operate this valve. It is operated by a DC power source. It works very well with a differential pressure across it.

Well, this one has a rather small reservoir also, so it will completely discharge itself into the tire in a few seconds, then slowly chug its way up to the 120 psi you require. However, that having been said, I find it does an adequate job airing up pretty much anything I have used it for. Have used it quite a bit over the last year and have had no problems. Remarkably easy to carry around and as long as you buy a good hose and pressure gauge, it should do the job. It won't be fast like a huge reservoir compressor, but it will get the job done.

No. It's a vacuum pump.. there's a distinct lack of pressure in the vessel when you use it.. :) and the way it's build I don't think you can extract enough air to make it collapse on itself.

No! The pressure needed is much higher than that offered by a gas station air hose.

No this item doesn't have that much Pressure.You'll have to purchase a backpack version or outsource your cleaning. But I would look into commercial water or air pressured systems.Two links for ideas.https://www.daimer.com/glass-cleaning-machines/http://www.solousa.com/store/browse/motorized_backpack_sprayer.html

I think it's too strong for your tank. I guess if you turn your faucet down, it won't overwhelm. A siphon sounds better.

Yes this product is fine for that. No additional equipment is required. So no air pressure needed.

I have say yes if I pull trigger if not on valve it has air come out, hope this helps

I returned mine. Could only get 130 PSI out of it. Connector did not leak though.

Hmmmm. You do need reasonable pressure to make it work. I'm concerned about your application, though. This is primarily a thing that allows you to "dump at home" where you don't have typical sewer hookups. You run the hose in the house and stick it into a convenient sewer drain. (I use a clean out.) Not sure why you would choose this if you had standard hook ups available. Does that help? It is a dandy gadget that allows me to clean and dump easily at my convenience at home on my Rv pad, Vs holding up a line at a gas station...

None so far. I don't expect it to operate like a full size compresssor. I think the manual says not to operate continuously for more than 2 hours. I am surprised they say it is good for that long at a time, but should get one out of a bad spot. Emergency being key here.

Its so easy, it takes about 2 min with a small shop vac and you reverse the hook up so it blows air instead of vacuums. I do this for air mattresses, floating island I have and a 12' floating trampoline. I use the small "Stinger" Vac available from Home Depot for about $40, a little more than a 12v mini useless pump.

It does not have a pressure release valve. You have to dispense the contents before opening. Or you can just tilt bottle until the pick up is not in liquid. Other than that you have to wait until bottle is empty and then release pressure by holding wand open until all the air is released.

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.

I am not sure about the air pressure-- you can manually control the spray in two ways: first you have a dial of assorted size holes that you can set and secondly the spray is trigger control ( the more you squeeze the trigger, the harder it sprays). I just have the typical pancake-style air compressor, so you don't need anything real big or of professional grade

Bar/mars/inches or terms related to the amount of vacuum a pump will pull. This is not a compressor so will make zero psi. It does not come with a gauge or valves. It has one vacuum hookup port only. It is a good unit and pulls a good vacuum. I use mine for stabilizing wood. A two stage unit will achieve a quicker job.

I actually used my compressor. I turned the pressure way down but you really have to be careful if you use a compressor. Just blow it up really slow whatever you use.
