I have 6 overflows that I made. I had them on a bunch of 40 gallon breeders. They come with U pipes and you can see in the pictures they have a silencer and a 3/4 union on the bottom so you can hook it up to hard pipe or you can cut off the union and slip a soft pipe on the threads of the bulkhead. They are used but don't leak. I've switched to sponge filters instead of a central filtration system. asking 15.00 each or if you want all 6 for 75.00 located in Renton for pickup.
