This post has already been read 6792 times!

Connecting PVC to Corragated Pips is not that hard to do. The secret are Fittings. There are fittings to connect most every type of pipe, unfortunately, You can not find these at Lowes or Home Depot. You will need to find a Good Plumbing Supply Company. The fittings are usually made of Polystyrene and made for Thin Wall PVC.

Using a 4" T, we are going to connect the Sump Pump Line which is 1 1/2" PVC

Here we are connecting 4″ corrugated pipe to 1 1/2 inch PVC. The Drain is 4″ which is gravity and will drain the downspout (roof drain) and also the sump pump which is in the crawl space or basement.

Using a 4" T, we are going to connect the Sump Pump Line which is 1 1/2" PVC

Slide the 3×4 inch Bushing into the 4″ corrugated fitting. It will snap right in!

Use a 3x4" Bushing to connect to the 4" T

Next a 1 1/2 to 3″ Bushing is used. It needs to be glued into the 3×4 inch fitting. Again, you will not find this fitting at Lowes or Home Depot. It is made for Thin Wall Pipe. Not Schedule 40 PVC.

1 1/2 Inch Bushing

Glue the 1 1/2 onch Bushing into the 3x4 inch Bushing

Now cut your 1 1/2 inch PVC to the correct length and glue it into the 1 1/2 inch Bushing.
That’s It!

Glue the end of the 1 1/2 inch PVC and slide it into the bushing
