Is there ever an example of a larger lateral pipe causing issues. Better to always go big?

Is there ever a scenario in which if you oversize a lateral line and it can cause issues? (Pressure, etc?)

For example, I have a 6GPM city feed currently. I am putting in a sprinkler system now.

In a year or two I will have a 15-20 GPM or more well system.

Can I put a 1 1/4 lateral pipe in now to support the future well supply even though that is overkill for 6GPM I will have for the next year or two. Any issues?

I dont want to have to put small pipe in now that will work with the 6GPM and then change it when it goes to 15-20GPM

Thanks

Bigger is always better. If the line is too small, the heads don't even pop up.

You'll want at lease a 2" pipe for that amount of water you expect. Distance will also impact flow. 1 1/4" is much too small and it'll put a allot of back pressure on the motor.
