Hmmmmmmmmm, ya think. Anyone want to wager a guess what is causing it?

Are those barnacles all over the piping?

Calcium carbonate deposits.

I've seen that caused by poor glue joints.

Freezing? That area doesn't drain.

UV rays made the plastic go brittle.. it cracked?

Nope, nothing wrong with the valve body or fittings.

My last guess...

"I turned it on manually and its just leaking.. it wont stop!"?

It should take several years for the VB poppet washer to fall apart.

Nope. The first pic is of the valves not leaking like the second pic, but they are still under pressure.
If you look close enough, the clues are there.

Close...er, but I'm not sure that is the problem, but certainly could be part of it.
Might be worth mentioning I didn't replace anything to get the leak to stop.
Still might go back and replace some stuff though.

Unless the VB bonnet was unscrewed, I don't know what the leak photo is showing.

Bonnet was not unscrewed. I showed up on the site, it was leaking, but not where it is shown in the pic. It instead was leaking at the flow control stem. Both valves were turned off via the flow control for an unknown amount of time. I'll be honest, never seen an A/S valve do what is shown in pic two.

Odd. Bad O-rings?

Another possibility, but remember, I didn't replace anything to stop the leaking.
I haven't broken the valve apart yet, so I'm not sure what condition the internals are in.

Sorry, losing interest in the guessing game. If you say the leakage was at the flow control stem, then there had to be some clearance for water to escape.

If you can't guess, then no one can.

Here's the deal. When I started to open the flow control, the valve opened, and water started blasting out from under the solenoid and a few other spots on both valves as shown in the pic. As I continued to open the flow control, the valve closed and the leak stopped. Once it was open all the way and backed down a 1/2 turn, the flow stem leak had also stopped. The flow stem leak was only occurring when the flow control was all the way closed. Needless to say, this is not the behavior I would expect when opening a closed flow control.

Well duhhh it was so obvious.;)

Used crappy valves.

Used crappy valves.

I beg to differ. Those A/S valves are rock solid performers. This is the first time I have seen something like this, and wouldn't be surprised if it were my last.
