“For a very long time in a 3 zone home because of extremely different zone lengths the longest one with endless turns and elevation changes could never completely stop gurgling. We installed the Supervent last evening and for the first 5 minutes it hissed almost none stop and now even zones I thought were good are improved to absolute silence. Those inexpensive air eliminator just don't do it. Fantastic product the more it runs the quieter it gets.”
“I believe this product was the better choice for the application. The information I needed to make a decision was complete and accurate on this site. Thanks to Plumbing-Supply”
“Installed air eliminator after 3 years of problems with air in my hot water heating system. After installation I never had to do a manual air removal for the whole apartment bldg. Very satisfied. By the way, installer commented that the Supervent air eliminator that I bought was the best that he knows of.”
