Rain water drainage - Max allowable lenght of run without access

[paro]

Hi All - I've spent the weekend digging a trench and installing 25m of drainage pipe to take the water from the roof out to a ditch that runs along the edge of my property. Is there a max length that I need to factor in for rodding etc?  access can be gained from the ingress and egress points but I failed consider installing any rodding points along the way.

 

Is this going to be an issue or can a professional deal with that no issue?

 

Thanks, Paul

P.S. Apologies, I've posted this in the wrong place but don't seem to be able to move it.

If it is rainwater nobody will care. 25m will be fine.

I'll take that. Thanks.
