no cap on the tee.. you want the open air ..second pic is correct...now you may get some water splashing up when you first turn on the pump ..it will stop in a few seconds... this tee elliminates the resistance that an elbo would cause also. if your running a strong pump you may want to stick a piece of pipe in the top of the tee 2or3 inches will do.

Need some advice. As I said, I was going to try to get some air into the filter.
So as a test I ran the rubber hose from my pump into the 1.5 in PVC pipe, but left the exit point of the rubber hose above the surface of the water in the filter. The idea was that the water would exit the rubber hose, hit the surface of the water in the PVC pipe, agitating it, and send air bubbles down and out the PVC swirler pipes in the bottom. It worked! quite well actually. The only downside is that I will have to extend the inlet much higher, because once the water filled the barrel, it started to back up and out the PVC pipe.

Now my question, Is it worth extending my inlet upwards, ( it will probably need to go a least a few inches above the lid) just to get air in the filter? I know that most of you said it will work fine with out the air. When it was running as is it actually seemed quite violent as far as airflow goes. So I'm wondering if to much air would be a bad thing.

Here are some pics of the progress so far as well as one of the filter filling up where you can see the amount of air coming through.

if thats your garden hose your running in the pics...they have way more pressure and air in their flow than a pond pump. dont expect the same results.

man, i'm just not following your question! Granted, I do have a glass of wine here, but I still don't understand what you're asking. Also, what are you doing just in case your barrrel clogs and overflows? Do you have an emergency pipe that heads back into the pond so it doesn't empty on itself?

LOL. Don't worry about it. I'm not gonna worry about getting air into the system anymore. I was just trying to be ambitious :alieneyesa: I hadn't thought about an overflow system yet. I am actually not too sure if I have enough vertical room to add in an overflow. mmmm time to get thinking..

I have had 7 of them and I always pay cash. I have had Corvettes since 1968 and I have not had a car payment in over 25 years. Leasing is for fools.

If you can feed a air line all the way down to the tee and make the turn the air would not push the water back up the pipe
Go for it

Feed the air line down the same pipe you have already made for the water inlet that feeds the filter bottom...push the air line down and were it tees, add a tee in the air line , to let it go both ways. let the air lines come out of the pipes on both sides,,
Then air will only come up out side of the pipe
