My hot water heat system had a Taco 400 HY-Vent that was about 25 yrs old. This Taco 400 HY-Vent was an exact replacement to the old one. It was very easy to update with this purchase.

Replaced an existing Hy-Vent that had gotten clogged over the years (decades). Worked like a charm, was less than half the price of our local big box store, and arrived in 2 days!

Quality is good however I found the exact part at a plumbing supply for half the price.

The high vent fit perfectly as expected. We'll need to wait a bit to see how long it takes for this one to leak.

Vinegar works well for internal and vent opening cleaning (off the system) - just ten or so minutes soaking followed by light stiff brushing will do it - do NOT soak for days, will eat up the metal. Three recommendations after pushing 40 years of use of these: (following assumes copper piping)

These vents are well made (robusto) and should last decades, and they're made in Italy, ciao.

I ordered this Hy-Vent to replace the leaking Hy-Vent on my boiler system. It is a direct replacement and easy to change. I have purchased other items over the past few years and have been so pleased with availability of exact part replacement and shipping times. Thank You
