Move sprinkler head - Flexible PVC, Funny Pipe or Poly?

[Carol]

I need to move a sprinkler head so that it will end up about 7 feet from the existing PVC line. The existing PVC line is 1/2" pipe. The head was connected to the line using flexible PVC connected to a funny pipe 3/4" elbow on one end and connected to the 1/2" line using a funny pipe straight barbed fitting with 1/2" threads at the other end. No glue was used at either end of the flexible PVC, as I was able to remove *both* funny pipe fittings from the flex PVC.



I live in Jacksonville, Florida where the ground does not freeze.



Ok, so now I need to move the head 7 feet from the main line:

1 - Should I use 3/4" *flexible* PVC (instead of 1/2" flexible PVC) to try to mitigate pressure loss (using some kind of fitting to connect the 1/2" pvc to the 3/4" flex PVC)?



2 - Would you glue it? (even tho the professional who installed my system 10 years ago did not)



3 - If not flex PVC, would you recommend funny pipe? Can I run it that far? Most of what I read says no more than 2-3 feet.



4 - If I should run hard (non-flexible) PVC, should I contine with the 1/2" size, or increase to 3/4" size?



Thanks!

Hi Carol,

Not knowing everything about your system I would say you have two options:

1. Continue with the 1/2" PVC to the location you want to add the sprinkler. I would use PVC primer and glue.

2. Use Funny Pipe. Funny Pipe makes the job a lot easier it uses no glue or clamps to install so there were no mistakes in your existing sprinkler system. I don't see aproblem with running it more than the prescribed 2-3 feet but use option 1 if you are worried about it.

Thanks for the help! I used 7 feet of funny pipe and it worked out just fine.

If you need to replace any of the "funny pipe" fittings in the future, I have a full selection of them on my website. They are called insert fittings.
