I installed a powered anode in 2016 and ever since air in tank. When the camp is un occupied for several weeks, air builds up in the hot water tank. If camp is being used the problem seems to go away. Question Would the instillation of an air bleeder (example Spirovent) solve this problem ? Any other solutions would be appreciated.

First off, did you buy it from Water Heater Rescue? And which brand of powered anode?

Yes, I purchased the power anode from Water rescue on 03/21/2017. I believe it is the Hex Head anode SKU27 for $ 253.54. Does that sound correct ?

Sorry, it is the sku25 on my AO Smith heater

Hello, You can take care of gas generated in the heater by adding a vent at the top.  This is done by installing a "T" in the hot outlet so that the side port on the "T" is facing sideways. Now take your hot water to the house from the side port.  At the top port, bush down so you can install a float vent. These usually have 1/4 or 1/8 inch threads. The only downside is that if you have hard water, the vent will plug up periodically and need to be cleaned with white vinegar at times. ;)
Yours,  Larry

Thanks for the response. I will try that in the spring when we open the camp up again for the season.

There may be another way to do it, but it won't work as Larry described because the powered anode sits in the top port of the tee. I suggest testing with a multimeter and possibly turning down the output some. At some point, e-mail me at mail@waterheaterrescue.com for testing instructions, and remind me who you are and the details of the situation. You won't want to turn it down too much, though, or you'll compromise the protection it gives the water heater.

Hello elenano,

I am Bob (Hathaway Pt. Repair) and originally asked if a Spirovent ( https://www.pexuniverse.com/spirotherm-vjr075-spirovent-3-4-air-eliminator ) would eliminate my air problem. I believe that Larry felt that a 2nd "T" added to the HW Outflow with an air vent installed would work. The believe that the spirovent VJR075 would take place of the "T" on the HW out line and eliminate any air. Unfortunately until the camp is opened up again in the spring, I wont know if this will work or not.
Your thoughts on this are appreciated.

Bob

I deal with powered anodes all the time. Larry is familiar with them, but it isn't part of his daily fare. The reverse is true of the air vents. I know what they are, but he's dealt with them more. My thought is he was thinking of a simple tee with the vent in the top and the water flowing out the side because he didn't realize that SKU25 uses a tee already and the anode has to occupy the top port. It might be possible to plumb a second tee past the side port of the first tee with the air vent it ITS top port, but I'm not certain it will work. Larry will know more about that.

I really appreciate all the input in this matter. Until warm weather and spring comes I am at a stopping point. I will try the "spirovent VJR075" as it is designed to be used in Hot Water system piping to remove all air in the hot water stream. Or I could just turn on a hot water faucet and bleed the air out and save some $$, but I enjoy the challenge. Should it work, I will try to send a picture of the install early next summer. The powered anode has fixed the smelly water problem and could not do without it. Great product, great support, thanks.

Hello,  The Spirovent is a nice unit, but might be overkill.  It is designed to remove air from a relatively fast flowing stream, while a standard air vent isn't.  But gas is generated slowly in the tank, so as long as gravity can be used to collect the bubbles of gas and they get directed to the vent, all is good.  Also, the Spirovent is 80-90 dollars while a plain Watts vent is more like 10.

As far as how to install it even when a powered anode is in the way, it would not be hard to add a second "T" just downstream of the first one and face a port straight up, for the vent to be installed into. :cool:
Yours,  Larry

Spring has come and as soon as I can get the water in camp going for the season (lake high water has washed out our road) I will keep all interested informed as to how the Spirovent Air Eliminator works for me. Thanks for all the input and suggestions.

Finally summer has come and the Spirovent installed. I came off the power anode T with a union then into spirovent and on to Hot out. Easy install and when Hot Water tank was filling, all air was vented out the spirovent until tank full with 0 problems. System now on for 2 weeks and no more air in hot water line. The spirovent JR may be overkill and pricey, but it is working really well and has taken care of my air problem. Thanks for all of your input in this matter.
