honeywell supervent

Randy T

I have a job that was completed a couple of months ago. We recently did some work to the system and I noticed the supervent not spitting air. I took the top of and cleaned the float and needle. After reassymbly it still doesn't spit air but I hear air in the pipes. This worked well when first installed. The pump is installed pumping away from the air eliminator and pressure tank. It's a 2" tapping supervent. The next thing I'm going to check is the internal wirebrush. Maybe this brush is all gunked up, I can't imagine that but anythings possible. Any thoughts on this problem?

if there...

was a lot of copper tubing you might be surpised how much flux ends up in the air vents.... cleaning the system after start up will help. kpc

i have a thought...

gate the boiler and purge it off the return to the supply side pump into the bucket and back into the return..a white bucket is best , then you can see what is in your system.....oh , And get rid of air.

It takes time

no air scoop catches all the air on the first trip through the purger, even with the micro bubble resorper types like Spiro, etc al

It takes a good sized pocket of air to cause some of the float type to work. Only when the float is surrounded by air will it drop and release the bubble.

Maybe give it sometime to work, Usually by the next day, IF all the zones have run and heated, it will be air free.

Now there are some installations where air removal is slowed by the piping concept. P/S and injection mixing are sometimes slow to purge. Not a bad idea to have two purgers in some of these arrangments. One in the boiler loop, and another in the secondaries. Especially if you have thousands of feet of radiant tube attached. Lots of trapped air potential in larger capacity (water volume)systems.

Slow flow rates complicate air removal also.

said, this is one reason why I have recently been using the Taco RMB. It scoops the system side, then my favourite, Watts air scoop for the primary. Nothing like hearing two blasts of air being eliminated at thwe same time!
