4” can be had at most box stores, the 6” and 8” is often quite a bit harder to find. Sometimes the box stores will have it, sometimes they won’t. A professional piping supply or plumbing supply may have it. One problem is the stuff has several names, and Skippy Stockboy usually has no clue what you really need. Look for ASTM D2729 stamped on the side, this is the thinwall stuff that’s plenty adequate, cheaper, and easier to handle than the thicker stuff like 3034. You’ll gear it called soil pipe, DWV (drain, waste, vent) and thinwall. Try to get your fitting at the same place to avoid a second hunting trip. Some Lowes stores stock the 6”, try there first…but I’ve never seen 8” in one. If you only need a short piece of 8” to hook to the inlet before you recude to 6”, you can use HVAC snap lock and transition to PVC. The 5-6’ of pipe leading into my dc is snaplock (7”) then transitions to 6” PVC for the balance of the system

I can’t help with a supplier but I can make some of your parts cheaper.
Check this blog about making your own “Y” fittings.

I use Locke Supply. They service a lot of the country but they don’t have a store front in every town. They might not have the cheapest prices but they are available with the larger stuff. I did price some 6” from them and found I could get 6 inch metal spiral wrap cheaper so why not go with the metal? This was my thinking on the subject. The 6 inch stuff was heavier wall and expensive in PVC.

Echoing some posts from above:

  • If you want to use 4” pipe, you can get it cheaply from Lowes/Home Depo/etc.
  • If you want larger, you will probably have to get sewer & drain pipe from a plumbing supply house. It is a hassle, and it is expensive.

If you are going larger than 4”, I would encourage you to consider spiral pipe from a place like Penn State Industries. It’s very convenient, and it eliminates some of the problems you get with PVC. The biggest problem with PVC is that the turns are too tight, and the spiral pipe has more gentle curves available that don’t have such a negative effect on CFMs. It is expensive, but you buy it once and get to be happy with it for life. And if you are up in the sewer & drain PVC sizes anyway, it isn’t that much more expensive to go spiral.

I paid $125 for 30 ft of 6 inch dia spiral wrap. It is a heavy wall and rigid. That is about a dollar a foot. They had to order it in for me but it was there the next day.

Im getting a grizzly dc that will do 1500 cfm Im going to ditch the filters and vent it outside. so i should have a lot of flow. I was thinking sewer pvc for the price. I found a website on how to bend the pvc I guess it really just comes down to what i can find the cheapest?

Look at Stumpy’s latest video, he’s making his own and fittings cheaply.

If you go bigger than 4”, make sure your collector can keep the air speed up. Bigger isn’t always better. 4” is fine for most tools, except a big planer or similar.

Grandpa, it has been a few years since I studied math, and it was abstract math at that, but I think your arithmetic is off.

if you bought 30 feet at 1$/foot that would be 30 dollars. I suspect you paid a little over $4 per foot.

Am I missing something?

Cheapest is a good way to go, but you may find most of the cost in the fittings…so price them out first.
