Having Issues with water seal on t300. Anyone else seeing these issues? It appears the t310 was design has been completely changed, I assume due to these issues.

Both are designed to be water tight.  Where did you find leaking in T300, thru the case/cover or Ethernet connection?

Had multiple units do this. All at 14 months. The last one did it at 11 months and returned to you 4 weeks ago. Still waiting for a replacement. Really disappointing considering the cost.

There's enough water inside to fill a glass. It appears that the units seals fail, due to reaction with salt air environment, resulting in ingress and eventually failure. We note the t300 has small vent hole on the top of the unit, not the breather. This is usually full of water.

I see... and would suggest asking for Failure Analysis on the returned units.
Small hole is water drain, shouldn't penetrate inside.

I asked for a failure anylasis. The response was, they couldn't do one. I'm really getting the feeling something is being covered up or ruckus don't actually care. We've just had another unit fail, when we attended it was full of water. Could here it sloshing around inside.... Interestingly, we replaced it with a t310, can see the design is 100%different and no valve on show!!

We sent two back, one in warranty one out. You still have one, 4 weeks now and the other you returned, becuase it had no RMA, I simply sent it back so you could see its a design fault. The unit was immediately returned, not even looked at. I'm so upset by the poor experience l, had loads of complaints of customers, becuase these are meant to be one of the best products on the market.

But in both cases you opened you didn't provide your reseller or purchase order details?  All outdoor APs have a 1 year warranty, but you have to buy support for longer. There is no history of water ingress to T300s, but yes T310 has changed design.

I'm trying to find out if other people are having issues with them, especially considering you've discontinued them and radically changed the design of the new t310

We currently have approximately ~116 T-series APs in production. We've seen several T300's go down due to water intrusion. I can only think of one I bothered to RMA due to the others being obviously the fault of the installer, we've had several mounted upside down, a few installed without GLANDs. That being said, I've asked a co-worker about a building of ours where there was water intrusion into 4 T300's. I didn't pay much attention at the time, but I seem to recall blaming the local technician in charge of mounting. I'll ping back when I hear back. Sorry about your experiences with Ruckus. For me personally, I've had several Reps and several sales engineers. Some were better than others, and I've had a few "put your supervisor on the line" moments with Support sure, but I still wholeheartedly recommend Ruckus's products. Support might be a work in progress, but this is something I can usually navigate with the help of my Reseller, and my assigned Engineers. If you have access to people like that, I'd engage them as soon as practical. 
Good Luck,

Welp, we just mounted a t300 and can see the pressure valve is open to the elements. i'll get back to you as to whether the pressure valve theory holds water.

Having one of several T300 just experience a failure because of this issue, the water isn't penetrating the pressure relief valve. It is getting into the radios because of a tiny (alignment?) port drilled through the back cover near the Ethernet port.  Your test setup is flawed because you put a shield over the top (your right mounting plate in this image) of it in your test radio image. That bar will minimize water penetration.  Take a dead T300, pour some water in it and hold it with the corner next to the Ethernet port down.  You will see the water readily drip out.

Believe it or not, they still haven't replied to a single email.
I won't ever be buying ruckus again. Super annoyed that they have officially dumped the T300 range.its not that old and now I have to tell my customers that its no longer supported....
Would you like to spend another £500 per unit!!!!!!

The t310 has had a design change. So this issue is no longer applicable. But none the less, they didn't want to know!!!
