Rear washer hose

congo_90

So I've a mate who is having trouble with his rear washer not working.
Car is a 98 Fiat Punto.

After popping the bonnet I found a leak coming from a small disc object on the hose. Its going from the pump to where the firewall is. (will post pics tomorrow).
Anyways I stopped the leak temporarily and we tried getting the rear washer to work.
I'm aware of a blockage somewhere in the hose from the firewall to the rear washer as the hose swells up before that joining disc.

My question is. Where does the hose route to from the firewall? Does it go along the pillars to the roof and eventually to the boot door or does it go under the door sills.
I'm asking to save me taking apart bits of trim unessacarily

Thanks in advance.

Is that disc a non-return valve? It could be blocked there.

I believe it is yes. The very words i was looking for lol.

It's not blocked. I pulled the hose off and it was allowing was to pass when the pump was on. I'll be replacing the valve anyway as it's fooked and letting water out.

Front washer is still fine as it's on a different hose.

I'm trying to think perhaps the hose got damaged from frost somehow from lieing up. This could partly explain the valve. Google didn't turn up any useful information on the hose.

I suspect its running on the passenger side sills until the rear pillar where it goes up into the roof. Anyone confirm?

If its swelling up the frost didn't damage it.

The first place to check would be where it goes into the bootlid to see if there is a kink in the pipe which could block it.

You could try a bit of compressed air but that may blow off one of the push on joints.

If you take the pipe off the jet at the rear and work the washer it will give you an idea if it is the jet itself or the pipe that the problem is with.
