Flexible plastic option for kitchen sink trap?

Hey guys, in the upstairs apartment which is rented, the drain brass pipe which is connected to the sink and the brass trap keeps leaking due to the tenants moving stuff around under there. Seems the bottles and whatever they store under there keeps hitting the pipes causing the pipe connections/fittings to break.

I am wondering if there is a plastic piping option to prevent this leaking please?

There is but it is often not recommended because the corrugations increase the chance of a clog. Even using one I'm not sure it would solve the problem because they are not all that flexible. I'd say you need to have a talk with the tenant.

I agree with Ray, I recommend staying away from 'flexible' fittings since they also can cause more clogs. Plus, they aren't like rubber like you're picturing, more intended to align mismatched pipes.

I would figure out some way to create a 'cage' around the pipes, maybe out of 2x4s or something to keep the cleaner bottles and such away from the pipes.

The pipes shouldn't leak if bumped.
I haven't had a leak call back in many years and I would if there was some problem.

Check the strainer baskets and the tailpiece/disposer for any leaks or signs of corrosion.

Disassemble the trap and remove the arm from the wall, dry all parts and use Teflon paste at the following joints:
Where trap arm meets wall, the trap mating/ground surface (bottom), and the joint where tailpiece inserts into top of trap.

These are the places most likely to leak.

I would go with the cage or box idea of Zorfdt. Just nailing a 2 x 4 under the "J" section (perhaps even having it touch it as a support) and nailed between the inside of the cupboard walls.
The important thing is if they are installed perfectly plumb. They should be able to take a little bit of knocking.

We figure it's the knocking because last time it leaked a metal fitting which screws on to lock 2 pieces of pipe was cracked. This saturday we will see where the leak is coming from and I will see about the caging situation, get back to you guys, thanks for the ideas.
