If the hardware store lacks a rubber stopper section, try a homebrew supply store, unless you happen to have a handy source of lab supplies. Some size of rubber stopper will jam-fit nicely - probably an #8 or #8.5. But I sincerely doubt that the material and size will work. 4" schedule 80 will flop when 18 feet long - 1-1/2" schedule 40 will act like a wet ...


Given all the ideas, the obvious solution would seem to be don't use sand. Instead, fill the bottom pipe with cement. Or fill it mostly with gravel with a few inches of cement or silicone sealant to hold the gravel in place.


Two ideas... Fill the pipe with sand, and then use an expandable foam like "Great Stuff" to fill the last several inches of the pipe. The polyurethane foam should stick well to the inside of the PVC, and the sand will not be able to pass through. A standard coupler has a lip in the middle to stop the pipe from sliding all the way through. Cut a disk of ...


If you plugged the inside of 1 1/2 inch Tee fitting (S x FPT x S) and installed one on each side of the horizontal legs you could than tighten a thread 1 1/2 inch plug to access the sand. To seal one end of the Slip hub of the tee: insert and epoxy an appropriate shaped disc (flashing metal, rubber gasket stock?).


A suggestion, I don't know if this would work out or not, you'd have to experiment ... Rip the pipe lengthwise with the circular saw first, flip it over and rip it again - now you have your half pipes. Stack those, and cut them with the reciprocating saw or the hand saw. It will be easier to handle. You'll get a lot more done if you bring something to ...


A 12" blade on the reciprocating saw. The blades in the link are the best blades I have used. They are strong and fast cutting. Use the wood cutting blades. The pipe will most likely be Schedule 40 which has a wall almost 1/4" thick, plenty thick enough so the tooth spacing will not rip out chunks, small chips yes, but cutting fast and quick as you said does ...


If you have limited time onsite I would not spend a lot of time making 20 cuts, regardless of the method. Just cut them into 5 foot lengths or whatever you need to get them in your car and finish up at home. I think you will be pushing the battery life of even a high-end lithium set making so many cuts through large pipes.


I've got some good experience using reciprocating saws, and I'd like to think that I'd be able to make acceptably 'straight' cuts, but there's no way they'll all be perfect. If you are going to use a reciprocating saw, use a blade designed to cut metal, as they have smaller teeth. Your best bet is a handsaw, not a hacksaw; the arbor won't clear. A jig made ...
