For the past few weeks ive been putting it off.... Ive fiddled and added things like hosepipe nozzels but it always seems to come back at some or another stage and its driving me crazy...

Ive got a hang-on DIY overflow box. It works 100%. It just randomly decides to start vortexing causing that suction noise which is a pain in the ass.

Does anybody have any good DIY step-by-step plans to fix this problem?

Could you take some pics? They might help people see what's wrong...

Have you tried a durso standpipe? (google it)

Durso standpipe will be my last resort. Im hoping to try more household items before I need to go off and buy goodies from the shop :whistling:

But here is a pic of how it is now;

stick plastic or glass above it, so the water has to go under it. must be about 1cm above the pipe

Try some clear pvc tubing ,I stuck a piece of 10 mm pipe down my overflow.The pipe vents the suction and that sucking sound will stop.Start with a piece of air tube and then try different size pipe untill you find the right diameter.I think the pipe I used came off a small external filter.
