## Questions & Answers

**Q: I have a pressurized leak 5 foot under ground, in a geo thermal heating system. will it detect that  do yo think**
A: The ULD needs the leak to be venting to atmosphere.  We do not make a unit that will work for underground leaks. bob@omnicontrols.com

**Q: If I have a pressurised product with tiny leakage will this pick it up?**
A: It depends on how small the leak is. Pressure leaks are found more easily than vacuum leaks. I have detected a .002 in leak with 6 psi pressure.

**Q: How does it find a possible bad bearing?**
A: didn't know it was used for that but it is possible it picks up sound so if a bearing started making noise it is possible

**Q: will it work to find underground water leaks**
A: No It Detects any pressurized leaking gas, including chlorofluorocarbon (CFCs), hydrofluorocarbon (HFCs), nitrogen (N), carbon dioxide (CO2), and steam
