Yes it does.
The only issue is the plumbing into the MBV - no leaks right now, and I can't replace the whole unit ($$$), so....I'm trying to decide what to do about that. I shouldn't say to replace the unit is expensive, as I'm not sure how much just the ball valve portion costs. I'm going to check on that right now....if I can find it anywhere. The MBV glue doesn't concern me as much as the rest of the plumbing, and we did successfully repair the leaks associated with the MBV, so if I can't find a replacement ball valve for it - I'm not going to cry, as I'm sure it will be fine.
