LOUD really LOUD

[nycsicktank]

my drain pipe is so loud. i can hear it from 5 ft away. i even redid my plumbing with 1 1/4 pvc pipe. the noise starts from my 45 degree elbow. i want it dead silence. i tired with the holes (3 large holes). nothing works. please help.

do you have a durso or stockman standpipe?

is the sound coming from the standpipe, the drain, or the sump?

have you tried a ball valve on the drain (sump end) to provide a bit of back pressure?

im not sure which one i really have. i believe it is durso.

from my standpipe, starts from the 45 degree elbow.

nope.

why do you have a 45 elbow on the standpipe.? it should be a T and an L. Can you take a pic?

If you look, the 45 is the L. :smash:

If your getting noises it means that your draining quicker than your pumping into the tank. If you match both and something gets stuck in the drain, like a rogue snail or soemthing then there is the problem of the tank overflowing. You create the holes in the top to provide a suction effect to create backpressure in the pipe and regulate the flow through it a little. If its still not enough u use a ball valve or gate (gate valve works better because you have more control) on the drain somewhere to create more backpressure. Also the durso should be 1/8 or 1/4 bigger than the drain itself. also if you drill a hole at the top of the durso and push in some airline tube and put a small valve on it you can control the air into it better. Also people say the airline tube end pushed past where the water flows off in the T part helps to minimize noise also. Also having the 45 at an angle also helps.

That all make sense?

You should have only one small hole at the top of the cap. Read this it will explain everything:http://www.dursostandpipes.com/

I like to use valves on top of the dursos for faster dialing in

 

[nycsicktank]

would it make a difference if i connect hose from my drain pipe? like i said the noise starts from 45 degree elbow.

try to raise the elbow higher or lower till you get the desired noise level. That is how i "dialed" mine in.

Another thing to try is to insert an air line into the hole so the air empties out further down the pipe.

Ball valves to balance the system works wonders

i did both. the thing is you can hear water rushing in even it is at lowest speed.

would vac hose be dead silence?

Have you checked the elbow for blockages? Perhaps water is rushing over something stuck in the line...

 

[nycsicktank]

yea nothings there. its brand new too.

where should i place the ball valve? after 45 elbow? or end of the drain pipe?

I don't see a pic of anything in your post. Could you check and possibly post it again ?

Thanks,
