    Can I go right from a valve with funny pipe to a RBird 1800 retrofit drip? Total distance is about three feet.

    Thanks,

    John

    Sure, but regular poly would be cheaper, and give you full flow, if you reconfigured things later.

    Sure as long as you use a top quality Water pressure regulator..

    I do things in a similar way.

    I use a marlex fitting (straight barb) directly out of the valve, and bring a funny pipe line to the surface. I then connect it to my pressure reducer/filter assembly (with another marlex fitting), and run .700 tubing from there.

    I've only used the 1800 Retrofit kit once, on a conversion job, just to try it out.

    Uhh, marlex fittings don't have barbs. Did you mean a barbed insert to MPT adapter? Or a funny pipe to MPT straight adapter?

    Thanks for the info. I was curious as to the pressure on the funny pipe going to drip. It would not be a concern when rotors or sprays but I had not put funny pipe from a valve to the regulator like this before.

    Wet Boots, you just don't miss a thing. hehehe :)

    I was referring to something along the lines of these, Since I use them with marlex street el's all the time I usually call them "marlex fittings", even though they aren't actually "marlex".

    Kinda like calling all swing pipe funny pipe :)

    Anyways, I use a 1" x 3/4" threaded reducer bushing, and then a "3/4" MPT to barb" (hehehe, marlex is easier to say) to adapt to funny pipe. Don't forget your teflon :)

    It was all funny pipe for a time, since it was Toro's invention, although they didn't call it funny pipe at first. On an invoice, 'flex extension pipe' looks much more official, not to mention more expensive.
