Does the unit have a valve for checking and adding pressure?

Yes. There's a valve stem centered on the bottom and covered by a cap. Precharge is 20lbs, I think, but for potable water system use, you'll need to add air up to your system pressure before installation. I used a little pancake compressor with some caution.

Yes, the unit has a standard tire-type air fitting that allows one to check and add pressure as desired.

Yes, it has the common Shrader type valve with cap for the bladder air pressure adjustment.

Yes, it has an open, close, and a mute button. To open the valve, make sure the sensor is completely dry and press open. It won't open if they sensor has any moisture on it. Works well. Good luck

The one I have does have a control valve. If nou do not you can always get one at a Home Depot or Lowes.

No The pressure guage goes in the plumbing not in the tank. The tank is kind of like a capacitor and is connected on mine with a T off the main line and my guage is in the plumbing next to my pressure switch

We never used it but yes there is a valve thst needs to purchased sepretly. Also we had purchase online. Local HomeDepot or Lowes do not carry it

No. It is only a simple check valve for a water hose type system. If you want to reduce the water pressure, then you would need to insert a restrictive rubber washer or else get a pressure regulator.

No-the hose/vacuum port, release valve, and pressure guage are all-in-one...a bit of a design flaw I'm afraid.

This one does not. Don't hold me to this but while searching for a CO2/portable inflator - pretty sure I saw one that had an pressure gauge. Something along the lines of a small hand pump with a CO2 attachement (two in one set up). Good Luck

It's a three way valve!!It's not a check valve, but I guess you could use it with a secondary discharge pipe so you can manually switch the location of the discharge.

No, i didn't notice if there is a valve, but this product is a really nice thing

No but make sure the hose is rated for the incoming pressure (typically not an issue).

Yes, there is a button inside the center hole that mates with the valvestem. Applying pressure on the valvesteam releases the air.

The one I bought did include a pressure gauge, but that has been a while back and I don't have the provider information. Most of the suppliers will have the entire package content displayed, or they can be contacted directly.

No. Valve and thermometer are installed by you. Makes for more thorough cleaning.

Yes, it does have a check valve. I've used several of these converting forklift tanks over.

No. Mine has pressure reading off 2-3 PSI. Since I know this I just adjust accordingly.

doesn't appear to have one, however, this is my 3rd unit in 3 years. The valve will stop functioning properly before the battery goes out anyway.
