Valve between air scoop and air vent?

Is it OK to do this? I have an old american air purger and I'm about to reconfigure my system a bit, I was going to replace the air vent (thing on top of the scoop) and thought a 1/8 npt valve might be nice for future service. I know the Taco hy-vents have a little fin on the bottom of them (think they call it a bubble breaker), so it seems putting a valve in between would render this feature useless.

If you want to use a valve instead of putting the vent right into the valve put a nipple and a coupling and then the the vent.

I don't think you'll have a problem either way... you've still got the 'bubble breaker' in the path...

I'm torn whether or not to replace the air scoop with a Spirovent.

Do air scoops go bad? I was just going to replace the air vent on top and call it a day (I also have to add a foot or so of pipe to the inlet of the scoop since the guys did not install it correctly). Not to mention the Spirovent is about $100 more than the little air vent.

Do you have a constant air problem in the system?

No? Then don't 'fix' it.

Don't move the scoop or don't replace it with a spirovent?

There is no continuous air problem, but we are doing some repiping so it would be a good time to do the changes while the water is out.

Well, if you want to make some 'improvements' to the system, then sure, use the latest and greatest if it fits the budget... but if it's been working ok for like ever, then it may not be necessary to do anything.

If you told me that you were going to set the system up to 'pump away' I would say to definitely go for it... but anything short of that might not really be much of an improvement.
