Automatic drain values for tanks

[Bigboomer]

Ok, I figured I would repost this so it does not get lost in our previous post about our new rig.

We are starting to compile the list of to do's for the new rig and curious to see if anyone has changed their tank valves to 12v automatic valves like Barker or Drainmaster in lieu of the old standard style cable pulls?

Although they are not particularly inexpensive (changing all three would come in around $450 if I did the work) we are looking at the ease of use without having to mess with pulling the valves especially since we all know how difficult they can get.

Let me know your thoughts.

Thanks,

Les
