Rear washer dribbling out

[J9HHY]

When I drive hard in my 172, water leaks out of rear washer jet as if nothing is stopping it? Is there some sort valve to stop this that's broken or the nozzle itself?

Hi mate. I had a similar issue with my headlight jets. I put an in-line non return valve in each feed pipe and not had any trouble since. They're a couple of quid from Halfords and easy to install
