    Re: Tapping into outdoor drain

    I take it that the Fernco will also directly go over and fit well on to an SDR 35 wye fitting.

      Re: Tapping into outdoor drain

      I thought I would update this old thread with pics of the final drain. I found a very nice document on the NDS website about how to design an outdoor drain system and how to calculate the drain sizes based on rainfall where you live etc.

      http://www.ndspro.com/images/stories...r-drainage.pdf

      Based on this I went with a single inlet channel drain appropriately sized for the patio.

        you should try using sweep fittings, especially on the 90's as when it comes time to snake or jet, you'll know why

        looks like sdr35 pipe which is much more durable and easier to navigate, but a couple 45's instead of a 90 and a wye and 45 instead of a san tee makes all the difference when it comes to snaking.

        nice job

          LOL - I had forgotten about using a Y + 45 as discussed earlier in this thread. Hope nothing goes down the drain that would require snaking or jetting. Yes, the pipe is SDR35.
