Rena in the installation guide described in detail about the loop and it works, no back flow of water.

yeah i did see it in the RENA guide. it is a good alternative to check valve and a zero cost option too

I too have my Rena airpump 3ft below tank ie 5ft below water surface level.
Initially install check valve,first time the valve produced whistling sound.Purchased another set of check valve (some call it one way valve),no sound,but found air supply reduced drastically.Currently not using any valve, so far no problem when I off the pump occasionally (when feeding tubifex),but I do have a loop as described,ie just let the hose elevate abt 6 inches above water surface before turning down into the air pump.

Me also better type in disclaimer : I am not responsible for any mishaps if anyone chooses to follow this method.

Thank you!



The "loop" in figure 3 is easy to do! You just saved bro mountain a trip to the LFS and a few bucks.

I looked at figure 5 and I laughed, recalling recently someone did something as silly but he submerged a brand new external UV filter into his tank, shorting the thing immediately. I believe the shock treatment (probably costing about $100) did made him wiser and he now wears a new afro hairdo too.

Cool! I thought this is public knowledge the loop thing.

I use a small cable tie to secure the loop and a plastic cloth peg.

Cheers
