external bean nosie

[Petercar (RIP Dec 2017)]

the one pipe in my external overflow  a bean style  is noisey    i do have lotsa water goin from my pump..so wjats a idea to quiet it... theres a sump under the stand  and its pvc pipe from the bulkheads to a 45 degree elbow and theres a foot of rubber hose into a sock
  its

one line shoudl be full siphon.. meaning full of water and no air..... full siphons are quiet.
one line shoudl be a trickle line.... meaning you have the valve on the full siphon set so just a trickle of water goes into the pipe.
the 3rd line is empty or dry ,most of the time.

if something is noisy you siphon is either running faster than the return pump and there for sucking air.... or your siphon isnt fast enough and there is too much water going down the trickle line.

either way its a valve adjustment on the siphon line to fix.  could use the valve on the pump too if needed.

I have a Waveline 5000 for a return pump  I can adjust it without a valve ....is there a hole in the cap of the main durso and one in the cap of the second line?

 

[Petercar (RIP Dec 2017)]

Should that first line be right full of water ?..

Yes from what I have read, full water, no air.

The return pump does not need adjusting. It is the valve on the first stand pipe that needs the adjustment. The 1st stand pipe (with the down-turned 90) should be a full siphon. To achieve this, it needs a valve that you can close some to match the flow of the water going into the overflow. It doesn't need to be 100% but very close. That way, only a tiny bit of water should be going into your 2nd standpipe (up-turned 90). The third standpipe should be set at the max height and is fully opened. That is your emergency pipe and it should never be used unless the first 2 standpipes somehow get blocked. By matching the flow, you are creating a full siphon and it will be dead silent.

Definitely no air in this pipe. Air is what you are trying to avoid in this setup as that is what makes the noise.

I don't have a valve at the sump end of the lines ... I do have holes in both caps. ..when I put my finger on the hole of the first line the overflow fills up.  But I can see how much full it gets

 

[Neopimp]

Sounds like you made a durso / bean mutation.

1st pipe.... No air... No holes... Just a valve to adjust flow.

Let's see a pic if the overflow pipes

 

[Petercar (RIP Dec 2017)]

its like a T and a 90 elbow and sa straight and a cap  for 2 of them ..one inch

 

[Petercar (RIP Dec 2017)]

im at home now..so i plug the hole on the cap of the one that fills the sump and it takes the water down below the elbow and sucks air

 

[Petercar (RIP Dec 2017)]

i have it queiter now    i turned down the pump speed

 

[Neopimp]

i woudl plug the hole and then turn the pump speed up until it is trickling intot he 2nd pipe.

You DEFINITELY need to put a valve on there. It needs to be between the stand pipe and the sump.  A 1 1/2" pipe can easily move 2000gph alone. There should be no hole in the end cap so a full siphon can occur. Once it gets going, you will see how fast the water gets pulled out of the tank. Slowly dial int he valve until the water is just trickling into the 2nd pipe. The 2nd pipe should have a tube adaptor in the end cap with a small piece of tube that is bent over and just reaches the top of the up turned 90. This way, if the 1st line jams for whatever reason, the water level rises, which then submerges the piece of tube and stops the air going into the 2nd stand pipe. This would then create a full siphon in the 2nd standpipe.
