I use this to spot check the gas service lines in my rental properties before I buy them, and during tenant changes. It's very sensitive, and will pick up the tiniest leak. Very nice tool ...

I just opened up this gas leak detector and ran it through the start up procedures, so far like it would be expected in the manual. Then checked for gas at possible leakage point of pipe/union joint and what do you know a little leak coming from the union/pipe . I can not attest to the longevity of the gas leakage detector but it seems durable enough and it also comes with a protective case with some granular gas testing compound for testing purposes. Good stuff!

Recently added a laundry room from the basement to the 2nd floor.....and had to run a good amount of black iron pipe to make it happen. I've never had great results using the soapy water method for finding gas leaks and wanted something a little more reliable. Having done some research, I decided on this General Tools unit.

I like that this unit has both a visual and audio alert when gas is detected. At first, I was questioning how well this unit worked as it didn't detect any leaks on my 30+ foot run of pipe, fittings and reducers. Then I went to the basement where I had a shutoff to the hot water heater that I knew had a very minute leak at the shutoff valve. It took a few seconds on the high-sensitivity mode to peg the meter. Just for kicks I checked the other shut off that fed an old gas lantern in the front yard and got the same results. Meter pegged.

I replaced these valves shortly after, and am confident that my home is now leak free.

NOTE: I read on another review (don't remember if it was for this particular unit) that someone had a meter that was picking up outgassing from teflon paste. I did a quick swipe of the wand over an open jar of teflon paste, and noticed the same. This meter was picking up a low-level gas leak from the paste that I had on hand. Apparently, the paste will outgas for a week or two and the meter will detect this. I used yellow teflon tape designed for gas lines, so this was not a problem in my application. Just something to keep in mind.

Overall, I am very pleased with this purchase and am glad that it came with a nice blow-molded carry case.

I haven't had this leak detector very long so I hope it doesn't break right after my review...

The unit comes in a nice carrying case for protection. and batteries for immediate use. I never use batteries that come with electronics (unless they are built in and rechargeable) so I put my own batteries in. It takes it about a minute to warm up for use (this is normal), but once it's charged, it does a great job finding any leaks I have when connecting gas lines.

Excellent product for keeping tabs on my anaerobic digester at the farm. It will sniff out the smallest leaks in our HDPE cover.

This unit is great. I recently purchased a camper and installed a new propane detector on the wall. The detector went off so I purchased a $25 unit at home depot that didn't work at all. I took it back and got another to make sure I didn't just get a bad first one and that one didn't work either so I purchased this unit. It comes in a great case and comes with a bottle of salts that are used to verify the unit is working properly. The unit is very sensitive and has a high/low sensitivity button. I am not sure why you wouldn't want it to be to on high sensitivity all the time but it does work.

Using this unit I was able to pinpoint two different problems I was having inside the camper and then find out that I didn't tighten the connection enough after I made the repair. This unit is worth the cost as it saved me from a possible deadly incident.
