Industrial barbs with teflon and oring. You can see the teflon through the plexy.

I have a question though. I tried hooking everything up and there is flow but it is very modest! if I hold up (in the bathtub) the tube coming out from the ek supreme I get a steady flow of approximetaly 40cm before the water falls back in the tub. Is this normal? Is this block that restrictive? Without the block the water coming from the pump outlet would move (even if submerged) the whole volume of water in the tub. Something more like a jacuzzi rather than a normal pump. Ideas?

P.s. comments on barbs are welcome!
Hi Alex,

1 Question that I have had is whether or not your pump is too powerful...!?!? As in: Waaaay too powerful. I'm wondering also if the acrylic top/o-ring is going to hold over the long haul.

10m (~33Ft) of Head and 8400LPH (~2220GPH) is more than overkill. Are you trying to send all of that through just the 1 block?

Kind of hard to explain, but your pump probably isn't able to function under those circumstances--its just too powerful. I'd say you are wasting a lot of electricity and going to burn out the pump. I can't seem to get the words together to try to explain what I know, but I've had this instinctive feeling for a while now. Maybe someone else will come along and offer an explanation, or maybe the words will come to me later.

Just imagine hooking up that block directly to the pump: 4" of tubing then the adapter down to 1ft of 1/2ID, attached to the block......What would you expect? I would expect disaster in 1 form or another. Tubing popping off, water squirting out from the acrylic top/o-ring......Something bad! 10m head and +2000gph is more than a lot! Much more...... That takes quite a bit of psi for a pump. I don't think that these blocks are really made for that kind of pressure. Even if the setup held--initially--I would lay awake at night over the long term worrying about it.

Again, hard to explain, but the 1/2"ID tubing and the block may be so restrictive--in comparison to the pumps ability--that the pump may not even really be able to get a decent start (so-to-speak) before its almost completely restricted. If the plumbing doesn't give....sooner or later: the pump will.... Hope that makes sense!

I have an update on my setup. I'll post it after while.....
