Walker570 Posted November 3, 2019 Report Share Posted November 3, 2019 I have a problem with my AA S200 .22 It has suddenly decided to lose all its air pressure. I can refill to 180 as normal and it shoots fine, go back a few hours later or overnight and it is empty . Thoughts Where do I start to look ?

oldypigeonpopper Posted November 3, 2019 Report Share Posted November 3, 2019 hello, what model is it ? and what fill adapter fitted, old type or T bar Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 3, 2019 Author Report Share Posted November 3, 2019 Old type AA fitting, Mk2. Quote Link to comment Share on other sites More sharing options...
Robertt Posted November 3, 2019 Report Share Posted November 3, 2019 (edited) I've had this and it was a cylinder valve leak. To test, detach it, fully charge it and stick it valve down in a pint glass of water. Edited November 3, 2019 by Robertt Quote Link to comment Share on other sites More sharing options...

There is also a very small amount of leakage from the edge of the brass fitting at the other end. Looks like a drive into Solware in the morning. Thanks for your help. Until I had a fiddle didn't know how easy it was to remove the cylinder. Might be just muck in the valve holding it open a touch. This little rifle has never failed me until now, so might just need a good service. Quote Link to comment Share on other sites More sharing options...

Robertt Posted November 3, 2019 Report Share Posted November 3, 2019 I replaced the fill valve. Think is was about £10 from ' Best Fittings '. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted November 3, 2019 Report Share Posted November 3, 2019 (edited) I had my little brocock suddenly leak from the fill valve .i stripped the valve .cleaned the whole area .including the springs and small ball baring etc. When i reassembled it was fixed and holding air . Just some crud in the valve . Edited November 3, 2019 by Ultrastu Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 3, 2019 Author Report Share Posted November 3, 2019 Thanks fellas. At £10 I think it deserves a new one The one I have was second hand and has had a lot of dead maggies and tree rats through it since. I will howver retain the old one and strip and clean and see if it returns to workable condition as a stand by. Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted November 3, 2019 Report Share Posted November 3, 2019 Fill valves are very simple .Usually just a small spring holding a ball baring closed against a hole .when u pump from the out side it "blows " the ball open letting air in .the spring makes sure the ball stays in the closed position when you remove the pump Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 3, 2019 Author Report Share Posted November 3, 2019 Yes it looks like a lot of crud has built up or the spring has gone weak. We will find out eventually. The so called protection cap on the end is anyhting but that as it has a large hole in the end which allows dust and dirt to enter. I may stick a 'plaster' on that in the future.

figgy Posted November 3, 2019 Report Share Posted November 3, 2019 (edited) Lots of the fill valves are serviceable. Instructions online how to do it. If you can buy a tin or small bottle of leak detector fluid. It's inert so won't harm anything but will show the slowest of leaks. Looks like cuckoo spit, the saliva looking stuff you see on grass.

oldypigeonpopper Posted November 3, 2019 Report Share Posted November 3, 2019 hello, get it serviced and will be like having a new PCP rifle, my friend has a AA 300 bought new and only just had a recent service done by AA, Quote Link to comment Share on other sites More sharing options...

Gives a good trail of bubbles from where its leaking Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 3, 2019 Author Report Share Posted November 3, 2019 There was very little doubt where this one was leaking, it was bubbling. More worrying was the very slight very small bubbles coming from the opposite end brass fitting joint to the 'pipe' but I'll have it seen to professionally, it has earned it.

figgy Posted November 3, 2019 Report Share Posted November 3, 2019 When you get it done are you going to have a reg fitted? Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 3, 2019 Author Report Share Posted November 3, 2019 The rifle has been superb as is and only recently in the last two days have I had this trouble. What advantage over what has been a seriously accurate shooter am I going to have by having a reg ...assume that is regulator ...fitted? Do not even know what one is I'm afraid.

Ultrastu Posted November 3, 2019 Report Share Posted November 3, 2019 (edited) Don't bother . It won't mke it any more accurate and its just another thing to go wrong (and they do - often ) Edited November 3, 2019 by Ultrastu Quote Link to comment Share on other sites More sharing options...
Walker570 Posted November 9, 2019 Author Report Share Posted November 9, 2019 New filler valve arrived from Best Fittings this morning and pleased to say the AA S200 is up and working again. Thanks for all the suggestions and was assured that if the rifle is printing accurately leave well alone and no need for service or regulation etc. Reports of tree rats on feeders so will be out in the morning.

One or two met Mr 17HMR where it was safe background in the meantime. Reports from beaters that some where exiting from one of the feeder stations today so looks good weatherwise in the AM and perfect place for the air rifle.
