Thanks DB and Woodduck, yeah i was worried i'd need to buy more caps and didnt want the expense as i still need a heap of triclamps, glass and the 90deg bends.
I can be my own worst enemy as i try to over analyze everything to try and get it right first time. But i need to remember to try and have a abit of fun with it all too, as it is juat a hobby. :handgestures-thumbupleft: :handgestures-thumbupleft:
So ill just make the downcomers out of ¾" pipe instead of ½". If you think thats not big enough just say so as getting a bigger piece is no drama as i would only need a small piece to make 4 downcomers.
