Is there a way to fox proof my irrigation system?

I've just spent the entire afternoon battling with the system, patching in bits of 13mm hose, because foxes love to chew it. I am at the end of my tether. There must be a better way.

How do I keep them off?!!!!!

I use a standard Hozelock system -- it must be delicious.

 

I put food out for them, not touched my hosepipe, yet

 

I've noticed foxes have chewed my watering cans, (plastic) on the allotment, I have a few scattered around.
I wonder if they are trying to get water in dry periods.

Maybe lay out some clean water for them in bowls.

But if its cubs doing it its probably just a game to them.
