Using Pvc Pipe For Downspouts
Most downspouts don t have a 50 foot run but i wanted to use a 50 foot piece of corrugated clear four inch pipe just so that we could see it in probably the worst case scenario.
Using pvc pipe for downspouts. The best material is schedule 40 pvc. Then cut the top 1 3 to 1 2 of top of the pipe off. But i did deliberately put a belly in at the end of a 50 foot run. To do this i cut the black corrugated pipe added a t and aimed the pipe upwards to the downspout.
Since my in ground pipe ran right past the garage i had the garage downspout dump in as well. Look at that look at that action that s going to remove any sediment. This time glue a sanitary t fitting to the pipe end and the other end of its trench. There are two piping materials i m aware of both are made from pvc that meet these criteria.
Instead i choose to use pipes with smooth inner surfaces thick crush resistant walls and tight sealing joints. On the house i used downspout adapters with leaf guards. This is the pipe that you see used for indoor sanitary plumbing purposes. Use standard couplings to connect the pipe sections.
Install the gutter and run your 1 5 downspout with 90 degree or 45 degree depending on your configuration. Continue installing pipes along the trench until you reach the second downspout.
