PVC overflow silencing

  • We are currently upgrading MFK. thanks! -neo
still quiet, only thing i do is pull plant debris off of the top sometimes. my pump motor is all i can hear really. my wife hasn't complained since i did it :) well.. not about THAT anyway ;)
 
Potential for an unattended tank overflow is there. The straws do make it easier to clog up with no way to releve the issue. This is why I prefer a beananimal overflow.

If you use a beananimal properly they won't overflow and the most silent you could imagine and handle big flow ig needed

That straw setup WILL flood your living room someday ....... its a matter of when not if.
 
that's not very productive input folks.. if u see some scenario that leaves me with a flooded living room let me know.. as far as i can tell it's no more susceptible to overflowing than any other pvc design, providing i do not neglect to simply look at it for a month at a time or more. there is a cover over the top that adds area to inlet so it is no likely to be blocked by a single large piece of plant, and the overflow is no where near being at capacity so when there is smaller debris building up i can easily see a change in the way the water is flowing into the inlet and clear it out.. what am i missing?

Not sure what you meant by not very productive input. But...... Lets look at what you have. Looking at your drain it looks like you have a single PVC drain with a cap thats had slots cut into it to skim the surface. Is this the only drain? Are there no back ups or 2nd drains for safety? Look at a design known as the Bean animal. It runs fully silent. And can handle more GPH then you will ever be able to push at it if done right. No chance of ever having an overflow. It is supieror to any other design due to these 2 things than any other ive ever seen. So if you only have the single drain. Then it has a cover. Then you have a larger tube filled with smaller tubes inside. You have taken up some space inside the drain tube. You may still currently be able to handle the amount of flow your pump produces so it seems like you havent resitricted it in any way. But it has been. You must prepare for the "Potential" That anything can happen. To say that a plant or debris or even what happens if a fish died or something from build up clogged it. Then your pump will overflow the tank til the sump has no more water in it. It is possible for these things to happen. To say not gonna happen or no chance is heading down a path of wet floor. Ask me how I know.. Slosh Slosh Slosh.. It sucks. Are you always with your tank? do you ever leav it unattended? Stay awake 24/7? It will happen durring these times at the most inconvinent when your unable to do anything about it. Not trying to be a jerk or anything like that. Just trying to explain from my experince of a wet floor at 3am due to something similar. There are 2 kinds of aquarist. Those that have had a water mess and those that will have one.

Look at a bean animal overflow. Its the only one ive ever seen that makes it pretty well impossible to overflow and it runs completley quiet. Im currently using that set up on my tanks.
 
i just meant saying "that is 100% going to over flow" without saying why isn't helpful so thanks for giving your concerns.. and i just remembered why it will NEVER over flow this morning. I forgot since it's been a long time since i designed the sump or have given it thought. the last baffle in the sump leaves only enough space to fit the pump. the pump will run dry before it ever over flows. that i learned from my first sump design, although it never over flowed, it just came very very close when it broke syphon. if you have an expensive pump and don't want it to run dry if your overflow clogs i guess make a bean overflow, but that involves drilling the glass correct? way more of a time/effort investment, and with careful design of the sump you shouldn't have to worry about over flow in either direction.
 
All you need is a ball valve in between the overflow and sump that you can turn to reduce the gap inside the pvc. W/ only running 200gph the overflow is outrunning the pump. By adjusting the ball valve to can tweek the water flow to match the pump. So instead of water rushing down, it hits the turned valve, slows down to reduce noise without sacrificing water flow. I have done this with success, and this seems to be the only thing that worked outside of putting something in the inlet that would cause the tank to overflow eventually. To prevent fish from becoming sump mates you can zip tie gutter guard around the inlet.
