Re: water sprinkler problem
Ok, drain the water bottle and pull out the pump, stick the end in a jug of water and see if it is working. If it is then the blockage is in the pipe or perhaps a bit of gunge from the bottle.
Check the bottle, is it clean? If not you might have to remove it and get rid of all the slime, this can wrap around the pump and cause problems.
I guess the return valve will be under the scuttle panel (black plastic panel under the wipers) somwhere, you may have to remove this to see, follow the tubes and find the join. Remove the join and see if water is pumping to there. If it is then the problem is at the jets near the screen but I dont think both would be blocked at the same time.
