Problem with Brava washers

My car recently failed its MOT due to washers not working properly. I've just come back from the garage, after they told me they were blocked and they've now sorted them - only to discover that the rear washer is now squirting liquid straight onto the floor from near the catch on the tailgate.

I've already booked in for a retest - so was wondering, do the rear washers get tested as well, or is it just a failure if the front ones don't work? And if so, how do I go about fixing this??

I had this problem age's ago with my Fiat brava 1.4. but my MOT man passed
it due to he knew i'd get it fixed. As it was only a blockage. he said only the front washer/wipers were important. the back washer jet never works on my car only the wipers. and I still don't have the washer working and every time it pass's the MOT.

Only the front wipers/washer gets tested..the back wipers get tested if
fitted but not the washer.Thats what my MOT man said 6months ago on my
last MOT.

its easy to fix, the pipe pops off. reomve the plastic cover on the hatch and then push the pipe back in its hole and its sorted, although i would glue it back in palce to stop it happening again

DO NOT use it while it is like this, it will wet the rear motor and damage it. this is a very common problem.
