Hey.

noticed my mk1 has a bailey recirc valve on it. i know these are prone to leak from previous experience but that was years ago.

are these any better now or should i pop a 007 on?

I have a compbrake one, pretty much the same thing at half the price. I would just go that way if you are looking at switching.

My Bailey DV30 has been on for 6 years with no issues.

I think the early Baileys were diaphragm valves which are supposedly more prone to failing than piston ones but if it ain't broke don't fix it.

It'll throw a 17705 if it's leaking.

great. just thinking along the lines of prevention whilst im going over it with a fine toothed comb
