Outback V Ballast Valves

Guys, one of my rear ballast bag has been filling up on its own, in my 2006 Outback V. Does anybody know the type of Orbit valve to replace them with. I'm going to change all 3 while i'm at it!

Thanks,
Rob

I don't know the part, but it is just a regular sprinkler valve. you could undo the top of the valve, sometimes junk can get stuck in the diaphragm and block it open. clean it out and good to go. sometime people remove the spring also, i guess this help fill faster.

Throw them things away. You can get replacements at Home Depot but why would you?

Thanks Guys!!
