External Durso standpipe isnt flowing fast enough

  • We are currently upgrading MFK. thanks! -neo
May be you need to add more water. Just keep an eye not to overfill your tank. Safe way to do is turn off the pump. Fill water from the tank and let it flow into your sump thru the drain pipe until your sump is 1/2 to 3/4 full. Turn on your pump, and keep an eye on the water level of the tank. If it get higher than the bulkhead, and it keep rising, then turn off the pump before it overflow your tank
 
I don't know that you needed to take the L off, maybe just turn it so that its pointing diagonally upward instead of diagonally downward (like it is in that picture).

1" piping should be able to handle your water flow no problem. The difference in pipe size could be whats causing the gurgling. If you change it out to 1" instead of 1.25" and it keeps making noise, we'll have to figure out something else.
 
also wodnering if it is possible to put a spray bar on the end of a durso? I cant think of any reason not but may have something to do with to much air so i thought id ask.
 
i cant help much on this, since ive only built the internal standpipes. maybe it's something about the design of the internal ones that makes it work properly? what if you were to add a tee connector with cap and elbow on the inside of the tank?

another thought, is this even considered a durso standpipe? looks to me like its just a regular overflow drain :confused:

^ this too. since you said it empties your sump, it could be that you dont have enough water in the system to keep up with the overflow. just keep adding water until it stabilizes. but if the water level continues to rise beyond the bulkhead, then something's wrong

never thought of that its not a bad idea to try out for fun once I get a canister to go with this sump. Make the t so its upside down with intake in one and the air hole up top. Ive also thought about capping the bulkhead and just making PVC overflow because I can get more flow that way.

yea thats just the regular drain on it that it came with and sucking air haha sorry for the misunderstanding. I was just trying to show the connecter size on the inside compared to the outside(wasnt really sure the size of the bulkhead it's 1" though) .:grinno: when i put my durso on (looks identical to every other external durso online) it doesnt flow fast enough with the smallest hole so I cant even play around with it too long because I have to keep shutting the system down and its all i got until fridays paycheck. :( And the water level ive filled the sump almost to the top and tried it and it still doesnt stop rising.
 
here is my durso it went straight into the 1.25" bulkhead adaptor but now im going to screw in 1" pvc and get a reducer to the 1.25" and see what happens. another site said it was a necessity to get the reducer to go a quarter size bigger for the durso than the actual drain.
