• Durso. Tuning methods.

  • Jeanne

I encountered a problem with setting up the Durso drain. I've tried everything, even danced with a tambourine, but it doesn't want to work properly. Sometimes it sucks in water like a toilet drain, and other times it draws in air, causing constant bubbling in the sump. If anyone has positive experience with this issue, I would appreciate some advice.

the same trouble. even the pipe size is larger than I soldered

Look at this method, it might help...

It turns out that the tube needs to be inserted into the drain pipe. I'll try it today.

What does Dursso have to do with it? I have Dursso in all my systems, and there don't seem to be any problems. Can you send a photo of your systems, showing the water level and adjustment valves? You can also check the forum - this topic has been discussed so thoroughly that I'm not even sure if it's worth discussing it further.

Yes, there is a lot of information there, and everything was done based on them and the bourgeoisie... But something is not right, I've been struggling for a year now. Unfortunately, I've never seen a working Durso in person (except for my own). In Donetsk, maybe someone has it, but it's a big secret; all I know are simple overflows. Yarik, if it's not too much trouble, send me photos of your overflows in private, or I'll have to ask to visit...

Dana6523

Why in private? I would also love to see it, or is it a secret? If it's not too much trouble, could you post a photo?

I understand that the most important thing is the diameter of the drain pipe. If I have a return pump with a capacity of 3500 l/h, then the drain should be made from a 40 mm pipe; otherwise, there will be problems, as I currently have a 25 mm pipe, which is causing all the issues.

Cynthia6578

Well, I'll post it on Monday, although there's nothing much to see - a drain is just a drain... Made of 3/4 inch and inch PVC pipes, glued. As for the air valves - I used to install a regular valve for adjusting air from the compressor, but lately I've just drilled a hole and covered it with putty.

Joseph1346

It's clear, but what if a newcomer comes in, where can they look? It would be great if there are photos on the forum, if it's not too much trouble, please share them, thank you!

Max, I think the diameter of the pipe will only affect the throughput of the Durso... but it should work even with 25 mm! Can't you "throttle" the return line? I would like to see what would happen.

Tonya

I return the return line. After the return pump, I attach a valve that costs 3500, and then everything is fine. But I would like to have full power. The return pump has a 20 pipe.

Could you show a photo or a sketch with the diameters and sizes of the pipes as you have them, where the water level is maintained? There might be some design flaw in the setup; usually, there are no issues with Durso when assembled correctly.

Erica

The overflow generally works, but I can't get it set up properly. It produces large bubbles (especially if you try to tighten the valve), and it seems quite noisy to me. The pump in the aquarium is OR 2500, with 32mm pipes, and there is a valve at the bottom. The water level in the shaft is 1-2 cm below the comb, and the water is just above the middle of the tee in the overflow. The air intake hole is 4 mm; if you make it smaller, it starts to suck in water. The valve doesn't help, as even when fully open, there isn't enough air, and the overflow starts to draw in water.

Tracey

Make a 6 mm hole and install a standard compressor tap with smooth adjustment! I have an ASKOL pump with a capacity of 6000 l/h, and a 1" pipe works perfectly. It's silent and doesn't gurgle!

Beth3383

Make the hole bigger or drill another one, one hundred percent. Here is the photo of Durso, as requested.

Andrew419

Have you looked at this link? An important point - at the bottom of the pipe - well, below the coupling - there should be a diameter narrowing and the air valve should be smooth.

Rita

Yarik, thanks for the photo. I have the same thing. Even the pipe seems to be the same. Is there a transition to a different diameter? I drilled a hole, and it becomes audible. Maybe I'm just too picky? I looked at the link two years ago, used it as a reference, but still, thank you. The air valve turns out to be small in diameter.

Katie4842

I don't have an air valve - I just couldn't find a suitable one. I drilled 3 holes, checking the operation after each one. The holes are about 1mm. Below the coupling, I have a ball valve installed. I use it to regulate the level in the return chamber. It's slightly pressed. So that the level is in the middle of the horizontal part of the Durso. Overall, it works like that. It's not perfectly silent. You can slightly hear the water and air making noise in the pipe.

Amber9312

I soundproofed the pipes! The necessary valves are in the Tero compressors! To prevent the air from making noise in the Durso, we are making a silencer out of a film canister!

Angel628

It is not possible to return the soul. The pump's resource is decreasing.

Alyssa6727

You can suffocate it. The pump's performance changes over time. At first, it buzzes like crazy, but after a couple of months, everything will settle down and you can open the gates. There won't be any overheating. What else is there to wear out?

Elijah7048

To avoid creating new topics, I want to ask if such holes can be used for a Durso.
