We have a small 2.5kw R410a split system that has a leak. Iīve been to check the unit today and there was 50psi standing pressure in it. I last checked it out about 5 months ago, and It was Ok then.

All 4 flare connections look good to me and thereīs no oil around them. There is oil around both liquid and suction valves though(under cap where you open/close the valve with an allen key). The caps were on tight, But still think itīs leaking from them.

Iīve been to the local wholesalers and they donīt sell the valves. Anybody got any ideas of where I might get a new one from, or possibly If i could repair the old ones.
