Leaking Orbit Valve

Unread postAuthor: MrCrowley » Thu Jan 03, 2008 1:26 am

Well I was putting a sprinkler valve I bought in America on my SGA gun and it starts leaking out the other end at any pressure, 5-100psi.

I took it apart, found loads of dirt and crap in it, washed it all out, cleaned it up and dried it off.

When I went to put it back together I accidently left the drill on forward, and f*cked up one of the threads for a screw.

So I replaced the screw with a slightly bigger one that fits well and put it back together.

Now when I go to charge the cannon up, I get leaks out of the area where the new screw is, and on the screw opposite (other side) it leaks around the side of the valve where the top meets the body of the valve.

It also leaks out of the flow control, or toggle switch area for some reason.

Took it apart, i'm in awe. No reason for it to leak except on one of the sides that is leaking(side with the normal screw) there seems to be a small indent, like it's been pried open with a screwdriver...

I'll get some pics up soon, anyone have any ideas?

Take it apart again, silicone sealer around the contact areas and screw it back together?

Yeah, don't have any silicon. My fault for that though, shot a nail through it accidently and sealed the hole up, but it didn't work so good and dried up :roll:

Anyway I'm looking for a fix that doesn't including fixing a commercially made valve with epoxy. I did try teflon to no avail.

I suppose you could use epoxy like Araldite as a filler, and if the surfaces are smooth plastic and rubber then you'll still be able to dismantle in in future.

I've done this before,and I can tell you now it will never seal perfect again unless you use some kind of silicon glue etc.I tried making gaskets the lot to no avail.Glue it or just live with the leak.

wierd.... pretty much this whole thing happened to me. I had an orbit, it leaked, i opened it up, put on screws from another valve, then i leaked out of the screws and that lever thing. Then because i didnt have epoxy on me i for some reason used silicone from another project.

I messed up the threads for the screw once before and I just sealed it with epoxy.

You know what is strange MrCrowley, you manage to put a bloody WATERMELON on your mums credit card but are unable to manage the feat of putting a tube of silicone on same. Wonders never cease to amaze me. :D

Did the silicon work?

The araldite did the trick for me.

@Nova

Hahaha, the valve wasn't troubling me at the time of the watermelon incident.
