Taco Hy Vent 400

I was wondering if anyone has had experience with the Taco Hy Vents leaking. Our hydronic system has the Taco Hy Vents piped into the return on each zone. Long story short, I suspect one of them is leaking as there are clearly water marks on the vent itself and occasionally puddles beneath the manifold in the morning. Seems to happen in the early monring hours as this particular zone is heating up for the day. The funny thing is that this is a fairly new system (4 years old).

I plan on closing the ball valves on each end of the zone, draining the zone, replacing the vent with a new Taco Hy Vent, and then refill the zone. Does this sound right to you folks and have any of you had the similar experiences with the Tac Hy Vents failing???

Many Thanks.

    Sure, they leak all the time. It's old school to install those high vents on the return side. Once the air is out, they aren't needed. If your system was "pumping away", you wouldn't need them. When the system cools off, they can let air in. Unless you have some serious piping issues, screw down the caps and leave them, or take them out all together, purge the system and thats that.

    Taco, Hy_

    The taco Hy-vent may leak if any system debris collects in the vent, hindering its performance. You can disassemble the vent, cleanout anything that may have collected, and reassemble it, this should resolve the leakage. Alternatively, you can purchase the 414 waste connector, allowing you to run this tubing from the vent to a nearby, slop sink, or drain. For your reference I have attached the submittal data sheet for the Taco hy-vent, and the optional waste connector.
