BC82 Posted April 28, 2014 Share Posted April 28, 2014 Anyone can advise me? My Diy overflow piping seems noisy, can hear sucking air sound. I modified my piping to follow durso pipe, just that instead of down into the bottom, I install it thru the side of the tank. Quote Link to comment Share on other sites More sharing options...

SRC Member tunicate Posted April 29, 2014 SRC Member Share Posted April 29, 2014 Hi BC82, You setup is quite similar to BeanAnimals overflow design which profess to be silent. You can probably make some changes using its setup info. http://www.beananimal.com/projects/silent-and-fail-safe-aquarium-overflow-system.aspx All the best Quote Link to comment Share on other sites More sharing options...
BC82 Posted April 29, 2014 Author Share Posted April 29, 2014 Yea. I copy idea from there. Then use durso piping idea. Ended up jamed. Haha. Struck in between, I using 2 overflow pipe, normal overflow pipe with air hose to reduce air and complete siphon when water level too high, the backup overflow use to control the water level.

SRC Member tunicate Posted April 30, 2014 SRC Member Share Posted April 30, 2014 Full siphon should take up about 90% of flow. Remaining 10% flow via pipe with air tube. Backup pipe with upturn elbow should have no water during normal operation. Quote Link to comment Share on other sites More sharing options...
megacue Posted April 30, 2014 Share Posted April 30, 2014 I think gate valve is better use and have to valve position had to be lower down. This pipe should be a full siphone with control rate via gate valve. There other two should be emergencies use Sent from my SM-N9005 using Tapatalk Quote Link to comment Share on other sites More sharing options...
BC82 Posted April 30, 2014 Author Share Posted April 30, 2014 I only have 2 overflow pipe instead of 3. 1 is constantly in siphon mode with gate valve controlling the flow and noise. The other upturn pipe, I use it to control the level of the water incase the other overflow pipe got jam. Quote Link to comment Share on other sites More sharing options...
megacue Posted April 30, 2014 Share Posted April 30, 2014 The noise is becos of air being suck in or water gush down as the pipe is not full. The outlet pipe to sump should be submerge in water, just below water level for ease of maintenance. By both end in water, no chance for air to end unless bubble from overflow. Yours is a ball valve not gate valve, gate valve is used for ease for fine adjustment. Sent from my SM-N9005 using Tapatalk Quote Link to comment Share on other sites More sharing options...
BC82 Posted April 30, 2014 Author Share Posted April 30, 2014 Ic. Thought mine is gate valve. But also can do some adjustment. U mean I should lower the sump pipe to just below water level ar? Quote Link to comment Share on other sites More sharing options...
megacue Posted April 30, 2014 Share Posted April 30, 2014 Yes. Lower the sump pipe to below water level. Actually the noise is what noise? Air suck noise or water gushing noise? Having having enclose full siphone with regulated flow via valve should solve the problem. That just my view, no expert.

jerome9731 Posted May 1, 2014 Share Posted May 1, 2014 you doing it wrongly. everyone thought you have 3 pipes for overflow, but the 3rd pipe furthest away is your return pipe am i right? if this is so, simple with 2 overflow, do a herbie style. center pipe, full siphon without the air tube. seal the air tube and adjust your valve till return pump is same as that full siphon pipe. this will be silence since it a full siphon without air the other overflow pipe will be your emergency pipe in case of things stuck in the full siphon pipe. so you just need to adjust till the middle pipe full siphon equal to your return speed and your emergency pipe is just there as emergency. the emergency wont be doing anything. if your valve is difficult to adjust to 100% full siphon with the returns , just adjust till it almost full siphon of the return and leave it, a bit of water flowing through your emergency wont make any sound. cheers Quote Link to comment Share on other sites More sharing options...
