How to Install a Catch Basin: PVC Schedule 40 DWV Pipe with 90- and 45- Degree Fittings.

Poor drainage near or at the house foundation can lead to water seepage into the crawl space or basement as well as other detrimental impacts. To alleviate this problem one solution is to add a catch basin to drain off the accumulating water from rain or snow melt to a low spot in the yard that is away from the house. Water runs downhill by gravity, so no pumps are required when the pipe is installed with the appropriate downward slope. The cost of installing a catch basin can be kept down by doing it yourself and purchasing quality materials at lower prices. This catch basin system in this video is 45-feet of 3-inch pipe with two catch basins (one at each the input and output of the water) and was done for less than $300 with the only tools purchased being a line level and string ($10). All other tools were on hand as typical tools homeowners already own (such as: round point shovel, spade shovel, small sledgehammer or just a regular hammer, utility knife, wheelbarrow, Sawzall, hacksaw or portable bandsaw, and extension cord). @Webideo

It looks like you kinda turned the catch basin into a dry well. Helped a friend of mine do something similar except it discharged into a 55gal plastic barrel that he got for free that was used for cooking oil. Drilled holes all over the barrel, filled the barrel about 1/4 in stone, and surrounded the barrel with about 2-3 inches of stone and fabric. Digging the hole was a pain in the ass, but it was fun times.

Hey ~ Im doing quite the same thing! Curious how do you connect 3in pipe to the input catch basin?
Mine is not really compatible? Do you convert to 4in? Or maybe lots of silicone?

Thanks for asking.
The catch basin hole and pipe are compatible with either 3-inch or 4-inch ("The NDS Spee-D Catch Basin Fits 4" Schedule 40 pipe and 3" and 4" sewer and drainpipe, corrugated pipe or triple-wall pipe...") but with the 3-inch pipe there isn't a tight fit and it is difficult to caulk. Caulking isn't required if drainage gravel is placed around the catch basin and pipe where it goes into the basin--so the instructions say. I did use caulk for the input basin, though. (Silicone caulk is the best to use.) I did this by wrapping the outside of the end of the pipe and catch basin with duct tape to hold the pipe in place and then to seal the outside of that gap between them and hold the caulk in place from oozing out while it dried as I caulked it from the inside of the basin. I used my fingers to push it into place this way.
In the next Webideo catch basin video the silicone caulk is shown in great detail at the very end of the video as bonus video footage ("Quick and Easy Catch Basin Installation" at minutes 9:13-9:36 in the video.
I hope that this answers your question.
