perforated pipe level? caped?

Do The perforated pipe need to be laid in the trench level? Do I have to cap the ends.

Corrugated black pipe?

Level no, should be sloped toward end.

Caps yes, need to keep debris out, just allow water in!

Welcome to the forums!
What is the purpose of this pipe? Locally we use that type of pipe for foundation drains.

You first have to tell us what the pipe is for.

Often you do not have enough vertical room to achieve a meaningful slope.

The lower limit for the weeping tile (perimeter drain pipe) bottom is about an inch above the bottom of the foundation footing. (You may not excavate below that level for fear of causing a foundation collapse.) Some gravel is put in between to help prevent dirt from getting into the pipe perforations. The upper limit for the weeping tile top is a few inches below the basement floor surface, call it the bottom of the floor slab. (Too high and the drain tile would be embedded in the floor slab and compromise the strength and might even result in seepage onto the floor surface through capillary action..)

But the weeping tile should not undulate up and down. If there is a hump in the middle then there is an increased chance the far corner of the basement could flood and you might need another sump pump pit.

Do not pull a sock around a smooth weeping tile. The sock will cling to the tile and the small approx. 1/2 inch circular parts of the sock over the holes in the tile will clog rapidly and cause the system to fail.

Drain field lines are supposed to be installed level and at the very end it would be capped. It's not uncommon for one line to be higher than another but it would be stepped down with solid pipe and then the next run would continue in a level line.
