Tiff 5000 leak detector
Hi all - just joined. I worked as a Domestic Appliance Service Engineer about 20 years ago in the days of R12, but have since re-trained and now work as a school teacher. I have only had a car with air conditioning for about the last four years and a few weeks ago the a/c stopped working. I can't bear to get my cars looked at by others so there was only one thing to do and that was kit myself out as cheaply as possible and repair it myself. Got the gauges at low cost (Chinese) and a second hand vac pump for free and have just bought a Tiff 5000 leak detector from a seller on ebay who advertised it as fully working. This afternoon I got down to checking it all out but the leak detector found nothing even though I knew from the gauges that I had a leak. I actually soon found the leak in a pipe that had corroded where it touched some sound deadening that had probably harboured water. Even then the unit would not detect the refrigerant (R134a). My question then, at long last, is have I been sold a duff unit or is it only suitable for R12 which would have still been the refrigerant in use at the time of its manufacture?
Thanks, David

Welcome David,
It is possible that you have been sold a pup, try the sniffer directly on a can of R134a. It may not sense that gas or the detector head needs replacing.
You can always fall back on the old favourite, soapy water if all else fails.
Be aware that the new oils for R134a absorb moisture very quickly. During any repairs cover any open pipe ends until the joints are remade. Also get a new filter/drier and replace that as the last thnig you do before pressure testing and evacuating.Brian - Newton Abbot, Devon, UK

You can't find a R134a leak with a TIFF 5000.
Try once with R22, it will work.
I still have 2 of those in the shelves somewhere but they became useless.
You need a newer model which can search for R134a.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Thanks Brian and Peter, I was rather thinking I had bought the thing in too much of a hurry!

Re: Tiff 5000 leak detector
There are TIF XU1's on Ebay for pretty cheap brand new that are an excellent detector. TIF give a lifetime warranty with this one and it detects pretty much anything. They will ship worldwide.
Hope this helps.
