General troubleshooting recommendations for your inflator:
My inflator makes a loud, high-pitched noise when inflating balloons

This happens when the balloon is not properly placed over the filling outlet. If you hold the neck of the balloon with two hands over the filling outlet, the helium flow entering the balloon will cause vibrations and make a loud noise. The balloon should be held in one hand between your thumb and index finger.

Push valve sticks or leaks

It is possible that Hi-Float is in the outlet and the outlet will need to be replaced.

If the inflator has not been used with Hi-Float or was exposed to moisture, we recommend spraying silicone lubricant into outlet (inflator should not be under pressure). Press the outlet up and down to lubricate. Connect the inflator to a cylinder and open the cylinder valve. Place a rag over the outlet and press down to blow out excess silicone lubricant spray. If outlet continues to stick or leak, the outlet will need to be replaced. See the Replacement Parts tab on the left for a replacement outlet.

Silicone lubricant spray can be found at most major hardware stores. Note: DO NOT use oil based spray like WD-40.

Inflator leaks

Conduct a leak-check test to confirm the exact location of the leak. See the “How to perform a leak-check test” tab below for instructions.

If the inflator leaks at the cylinder connection, close the cylinder valve, bleed the pressure out of the inflator, and firmly tighten the cylinder connection. Repeat the leak test.

If the inflator continues to leak, remove the inflator from the cylinder and try it on another cylinder. Repeat the leak-check test. If the inflator does not leak on the new cylinder, we recommend returning the original helium cylinder to the supplier for credit. (In some cases, the cylinder valve will have bad threads that cause the inflator to leak.) If it is not the cylinder valve, replace the O-ring for the cylinder connection.

If the inflator leaks somewhere other than the cylinder connection, return the inflator for service.

Pressure gauge concerns

If the pressure gauge goes up and down every time a balloon is inflated, this is an indication that the cylinder valve is not fully open. Make sure that the valve is open completely to correct the problem.

If the pressure reading on the gauge is inaccurate, it is more than likely that the inflator has been dropped or bumped during transit. The gauge cannot be re-calibrated and must be replaced. See the Replacement Parts tab on the left for a replacement outlet.

Foil balloon inflation is too slow

If the automatic foil balloon inflator seems to operate too slowly, confirm that the balloon is pointing downward during the inflation process. If the internal valve on the foil balloon is folded over, the flow will be restricted and inflation will be very slow.

Please note that Conwin’s Auto-Fill Foil Outlets are designed to inflate foil balloons at a slower flow rate than latex balloons to insure that the foil valve is not damaged during the inflation process.

Inflator makes a loud popping noise when inflating balloons

This is caused by the pressure alert valve being activated by a sudden change in pressure. We recommend trying the inflator on a cylinder that has less than 2400 PSI. First, close the cylinder valve and release the pressure from the inflator, then slowly reopen the cylinder valve. This will avoid the extreme pressure spike from opening the valve too quickly. If the problem persists, return the inflator for service.

How to perform a leak-check test

Use a spray bottle filled with soapy water and spray around the area where you suspect the leak is located. If large bubbles appear in one area, then you may have a leak. Be sure to thoroughly clean your inflator immediately after testing to avoid water damage.
