I have a problem with the windscreen washer rubber line where it joins the T valve line where it splits for each washer unit.



The red button on the top is allowing water to spurt out not getting to the washer units.



Is this a faulty valve or is it something else causing this fault.


The T-piece is also a non-return valve which has a small spring loaded rubber diaphragm in it, water escaping from that little hole indicates the diaphragm is perished and the t-piece needs to be replaced, beware, if you replace it with a standard t-piece you will also need to install a one way valve upstream of the t-piece, otherwise you will get a very delayed response from the squirters every time you use them.
