Hello all~

I've got a job at a apartment building that is framed and will be pumping into basement through a hole in the floor. I will be using 4" rubber and steel. My question is do I have to have radius pipe to go from the floor through the hole into the basement or will the rubber hose work with out kinking? I would use radius pipe if I had one but not sure I can find one in time. Suggestions ? Thanks

The 90 would be the best option,even reenforced hoses tend to kink.Keep on your toes for plugging,the drop will get you.

Figure out someway to tie it up to keep it from kinking.

LAY A PIECE OF 6" PVC NEXT TO THE HOLE FOR THE HOSE TO ROLL OVER AND INTO THE HOLE.

I think those are all great ideas. Just don't prime out to fast or you will plug, if your just going down one floor it shouldn't be a real big deal. I would find another pump company and call and ask if you could borrow a 90 cause that would be a lot safer

Boy 4" is some heavy stuff to go vertical. But like Ed said get a come along or ratchet strap, wrap it around the hose 2-3 times so it won't slip then tie it up to relieve the pressure.

cut a quarter out of a tire rim (90 degree cut) and strap it to the hose.
