Has anyone ever seen a 2" to 1" reducing coupler? I am experimenting with a standpipe design, and this would be ideal. It HAS to be PVC, or at least something rigid that I can shape...

Thanks!

Have you tried usplastics.com? If anyone has it they would.

You can't use a bushing

You may need to use a series of reducing couplers... I've had to do that on my lawn irrigation... you just put one inside the next inside the next....

I was just at lowes and looking at the reducers. I agree you will need 2 or 3 fittings to take it down from 2" to 1".

Nope can't use a bushing, I need the tapered shape of a coupler. I have seen something similar, but I think it was 3" to 2"... I guess I may have to go with a series of them and see if that works.

Sometimes I have better luck finding these sort of unusual parts at smaller, locally owned plumbing supply and hardware stores.

Steven has a good point.. I have had better luck finding less common items at plumbing supply places instead of the mega super hardware stores... that is if there are any plumbing supply places in your neck of the woods left...

I don't think they make a 2"x1" reducing coupling. I just checked three different online plumbing supply places and I didn't see any that size. All they have is 2"x1.5".

I'm using a 2" Stockman standpipe over a 1.5" bulkhead drain. If your drain is only 1", all you need is a 1.25" standpipe. Use a ball valve just under the drain to regulate the height of the water column inside the standpipe. At least that's what I ended up doing. I try to keep the water level inside the corner overflow compartment no lower than about 1.25" below the weir and I keep the water level inside the standpipe fairly high. There is a sweet spot that results in very little water noise at all. If you don't hit it just right, you can even end up with that stupid flushing sound over and over again.

It's all a matter of balancing the water height and the air hole in the top of the standpipe and the adjustment of the ball valve on the drain. You just keep playing with it until it comes out just right.
