I am setting up a used Elos 120 xl tank. Its about 10 years old and the overflow is different than the new ones I see on the web. My question is it has a 1and 1/4 drain pipe and a 1/2 inch return. The 1 and 1/4 drain has a broken fitting in the top which I am assuming was a valve to let air in to keep the drain quiet.
Does the single 1/2 inch return handle enough flow ?
Also how much water runs out of the overflow and into the sump? It looks to me like a fair volume will run back in the case of a pump stopping.
Anyone who could explain how they worked when they were new would be greatly appreciated.
thanks
