Mine seem to be really poor and let out a drizzle similar to the last stages of urination. Also, the spray is not instant, like its building up.

I've tried the old pin in the jets, but am thinking it may be something else.

What else can I look out for?
On one of my old cars had a non return valve, it kep the water in the lines, so it can spray out quicker. Is there one on the Scoob?

Its a MY00.

Thanks

 

Mine are rubbish too (RB5) - changed the washer pump and slightly better but never seem to have all 4 jets working at the same time! No idea if you can get different heads that fit into the bonnet?

 

Should have a non-return valve in there.

One of mine(drivers) was really **** poor. I changed the pipes for silicon and its better.

I imagine crap will build up over time and block the pipe work.

 

Give them a quick blast with an air line, works a treat .

 

Micky is right. Each side has a little black non return valve a couple of inches before the nozzle. These got blocked and will need replacing.

Halford do these valves for a couple of quid.
