BRS media reactors - input from owners please

[H2o2]

Just thinking maybe it is siphoning out to some degree so maybe put the flow valve on the outlet inside of canister to keep the under pressure just thinking and not being able to try right now

I used to use the BRS reactors, but I never had any air problem with them.

Not a bad idea Harry but if air is getting in through say the head then it won't help
But if it is still happening in a couple hours I'll give it a shot - can't hurt to try

Now we're getting somewhere
Thanks everyone

Does the air stay gone, or does it come back over time ?

[duncangweller]

If I unscrew the canister a little the air disappears but sure enough it will come back pretty quick. I just live with it but maybe I'll email BRS and see if there is a reason why it happens.

On mine (9 months old) there's a little red button on top that releases air.

Do you use that button only after a media change, or do you have to purge air between changes ?

[mseepman]

Usually I have to use the red button after a media change and about a quarter of the time I have to use it again during regular use as some air builds up.

Looks like I may have found/solved the issue

I ran the second reactor through a bucket of RO for a couple days
At first it had issues, but upon re-seating the canister it behaved properly

Tonight I took them both apart to compare stuff and there it is ...

The sealing gasket on top of the trouble cartridge was up and sideways a bit
I've put it back where it belongs and it's been good for a few hours now

I'll report back tomorrow with the final results

Fingers crossed ....

If it looks good I'll write a review as I'm pleased with everything else about them

[gregzz4]

I don't want anyone to be mislead by my previous post as my diagnosis was incorrect. It has nothing to do with the cartridge sealing gasket

What 1eyedjyde said makes perfect sense

After days of still getting air in the reactors I think I've found the issue.
My pumps were quite close to the last baffle and it looks like they've been picking up micro bubbles. It was never an issue with the TLF150s as any air introduced can burp out on it's own, but the 'RO' style canisters trap any introduced air which then builds, and builds and ...
I had to use a flashlight with my sump room lights off to spot the bubbles

I've moved the pumps as far as possible away from the baffle and hope to report back that the issue is solved. I'll give it a couple days before I do so

I'm loving this reactor style for ease of use, and in my case the spread through the media is far superior to that of the TLF150s
