compressor problem, advice please.

ok i bought a 100 litre compressor there a while ago. now, when i turn it on it fills up as usual. when it fills completely it's purges like normal but it keeps emptying until the compressor starts to run again. so basically, runs and fills, empties itself until it runs and fills again. it's pretty annoying. any help is much appreciated.

Non-return valve, where the delivery pipe joins the tank. Try dismantling & cleaning it. Have a look in my albums for some diagrams.
