We have been using a coiled (spiraled) PVC discharge hose on our 3" dredge. It seems to be developing a lot of leaks due to the rocks beating up the hose as they pass to the sluice. It's also really bulky.

Would a 3" heavy duty lay flat hose work better? Would it be flexible and durable enough to handle the rocks and other stuff the dredge sucks up?

One big advantage of a lay flat hose is It would certainly be easier to tote the the stream than the hose we are using now. 

Thanks for any input ----------------------------------
