[eurocooling]

Got a leak on some pipework from outdoor unit to indoor unit checked the flare there's nothing,shut vavles on compressor are shut pressure still dropping pipe run is 3m pressure is 300 psi but dropping very slow can someone help

check the evaporator, expansion valve, look for oil marks...you have 300 psi with the compressor off? (never heard of that **** b4) maybe your gages are crap?
Good luck! If you can find it keep on looking, it's there, btw, dont add any of that flourescent crap.

come to think of it maybe you have 300 psi with the compressor running, and after U shut it off the pressure keeps on dropping, if thats the case then dont worry, it's equalizing... low and high side, wait until they are = and then maybe go back 2 school?

If I'm reading this right, you have 3 meters of piping.

That should take all of 15 minutes to leak check while under pressure.

More likely he put nitrogen in to 300psi and still can't find the leak, which is why he's asking for help here..?

It could be leaking past the service valves into the outdoor unit but i have seen a few new evaps leak so i'd be looking there first with some leak spray.
