TANK NOT HOLDING PRESSURE

As our product page explains, be sure to “test” your new POWER INJECTOR with nothing but water before loading it with mixed chemicals. These systems should securely contain and hold air up to 90 PSI and not leak when charged.

If you hear air escaping or note a leak after charging the system for the first time, check to see if you can identify where the air/leak is releasing.

WHERE TO CHECK FIRST

There are two likely locations and both are easy to troubleshoot. This will only take a moment and in most cases, can be fixed on the spot.

The first area to check is the seal that sits under the spray system. The Spray System screws “into” the tank’s threaded neck and should have a green O-Ring.

Click the picture for an enlarged close up view; note how the O-Ring sits above the threaded section that fits into the top of the tank.

These seals will wear over time and they can get out of position easily. If you notice a cut or any section embedded to the threads below, replace the seal with one from the included repair kit.

When properly fitted, it should look like this when the Spray System is attached to the tank.

Now if you suspect air is leaking from this joint, add a drop of dish detergent to 1 oz of water and lightly mix it. Next, dip your finger into the mixture and then drip the water/detergent over the seam. If air is leaking, it will bubble.

If you are certain air is leaking here, try adding a second green washer to the Sprayer System. Be gentle when stretching it over the threaded section to avoid cutting the O-Ring. When properly fitted, it should look like this:

When properly fitted onto the tank, this configuration should look like this.

When properly secure, this should keep the tank sealed. If you find air is still leaking from this section after a second O-Ring is added, contact Tech Support.

Remember, hand tighten only. It’s always better to “under” tighten so if you find air is leaking after adding a second O-Ring, go ahead and tighten it a bit more just to be sure it’s not too loose.

AIR VALVE IS LEAKING AIR

The Schrader Air Valve is where you connect your pump to pressurize the tank. This valve is the same design you will find on most any car or bicycle tire.

These valves are replaceable (there should be two in your replacement parts baggie) and can easily get loose.

To see if your valve is leaking, you can apply some of the water/dish detergent mixture to the hole at the tip of the valve to see if bubbles form. If it does, you’ll need to utilize the red Air Valve Tool included with your replacement parts kit.

Use the small end of the Air Valve tool to tighten the valve stem. The “notch” of the tool will fit over the air valve and allow you to turn it in two directions when properly inserted.

You’ll need to slide the small end of the tool into the valve stem and then get the notch of the tool fitted over the valve which is rectangular is shape. Once the valve is fitted in the tool, gently twist clockwise to make it tight.

These valves routinely vibrate loose during transit or they can come undone after several tank charges. They also use a small O-Ring that can get damaged so if you tighten the valve stem but find it continues to leak, replace the bad valve by unscrewing it and then install a new one (from the replacement parts baggie).

Air Valves are not likely to be “bad” out of the box BUT they are the number one location that leaks because they arrive a bit “loose”.

Now if you are certain yours is leaking at the valve stem AND it still leaks after following the steps above, contact Tech Support.

HANDY CAN AND INJECTION TUBE TIPS

 

*** ALWAYS REMOVE THE JET STREAM/INJECTION STRAW NOZZLE BEFORE ATTACHING RED STRAWS OR THE 50″ INJECTION TUBE ***

***  ALWAYS CHANGE NOZZLES WITH THE SPRAYER SYSTEM REMOVED FROM THE TANK SO YOU CAN ASSERT THE NEEDED FORCE TO INSURE PROPER NOZZLE FIT (SNUG AND LEAK FREE)  ***

The white Jet Stream Nozzle will accept the 5″ Red Straws as well as the 50″ Injection Tube. But you need to remove the Nozzle from the Sprayer System before inserting any straw. If you attempt to fit a straw onto the nozzle while it’s still on the System, you will damage the internal valve stem!

BEST HANDY CAN POSITION

When mounting the Handy Can to the tank, keep the Schrader Air Valve pointed toward the red trigger like this:

The Handy Can is designed to be “loose” when properly mounted. This insures it has plenty of room to be mounted and unmounted without damaging the Valve Stem.

The original fit was too snug which led to valve stem damage and accidental releases.

*** IT’S BEST TO USE THE HANDY CAN WHEN THE SYSTEM IS ON THE GROUND AND YOU ARE USING THE 50″ INJECTION TUBE AS SEEN ABOVE  ***

If you need to use the 5″ Red Straws, remove the Handy Can and use your finger to spray. Keep the Air Valve pointed toward you so it can serve as an “anchor” for holding the tank as illustrated here:

***  ALWAYS WEAR RUBBER GLOVES WHEN POWER INJECTING AND IF YOU FIND ANY SECTION LEAKING, STOP TREATING AND FIX THE SYSTEM BEFORE CONTINUING WITH YOUR APPLICATION  ***
