Res construction
 

Hi to all
Just about to finish up my hybrid water setup and was wondering if it is all right to have the return to the res slightly out of the water to give some visual flow meter ( the res top is transparent). I'm guessing that as long as the feed is always submerged and the res is at the top of the system then air will not get in.

Any reply greatly appreciated.

Yeah that wont give you any problems at all...

Suggestion...make sure the return flow is aimed away from the intake supply tube. The returning water "splashing" into the res where the other tube is located will help push air bubbles to where the pump supply tube can suck them up and into the system.

You could always stick the fan section of a small gutted heatsink fan on an axle right at the return to make a cheap flow meter and have the return tube under the water lever for no air bubbles.

Only just got back to check for answers and i never thought of the splashing problem. I could have messed up and not been the wiser.

All hail the pro cooling forums :p
