How to Detect and Address Oxygen Leaks in Your Veterinary Equipment

E Tanks

1. Ensure the flowmeter knob is in the off position.
2. Turn on the E tank and wait for the needle to stabilize on the gauge.
3. Turn off the E tank.
4. Monitor any drop in pressure on the gauge after ten minutes.
   • Line pressure should not drop more than 4 psi/min, and there should be no audible leaks.
5. If a leak is heard or the pressure drop exceeds 4 psi/min:
   • a. Check and tighten connections and repeat the above steps.
   • b. Call your Vetamac service technician.

H Tank with Anesthesia Machine Connected Directly to the Tank

1. Ensure the flowmeter knob is in the off position.
2. Turn on the H tank and wait for the needle to stabilize on the gauge.
3. Turn off the H tank.
4. Monitor any drop in pressure on the gauge after ten minutes.
   • Line pressure should not drop more than 4 psi/min, and there should be no audible leaks.
5. If a leak is heard or the pressure drop exceeds 4 psi/min:
   • a. Check and tighten connections and repeat the above steps.
   • b. Call your Vetamac service technician.

H Tank Connected to Central/Hospital Supply

1. Disconnect all anesthesia machines from the wall or ceiling (if possible).
   • If machines remain connected, ensure the flowmeters are turned off.
2. Turn on the H tank and wait for the needle to stabilize on the gauge.
3. Turn off the H tank.
4. Monitor any drop in pressure on the gauge after ten minutes.
   • Line pressure should not drop more than 4 psi/min, and there should be no audible leaks.
5. If a leak is heard or the pressure drop exceeds 4 psi/min:
   • a. Check and tighten connections and repeat the above steps.
   • b. Call your Vetamac service technician.

Leaks and quick connects

1. Determine which end is leaking. It could be the male end that plugs into either a female quick connect or in a wall port faceplate. The female quick connect or the wall faceplate could also be the source of the leak.
2. Plug the male end into at least two different connections to see if leak repeats. If it does Vetamac recommends and can replace the male quick connect on that particular hose.
3. If the male end only leaks in one connection most likely it is the other side of the connection. If it is a female quick connect Vetamac can replace it. If the faceplate is leaking Vetamac can repair it if we have access to the repair kit for your particular brand of faceplate.
