Actually I'm a fool, I think I've just noticed a way to shorten the pipe looking at a photo on my phone 

On post 20 I meant horizontally, I should try to sleep more 

It would be easier to show with photos, the only way I could do that is if I could send them to someone to put on here for me 

I'll pm you my email address - should be there in a minute

Thanks, might have to send 1 at a time to get them to go through today 

Here are the pics:

Looking at the pics, your spraybar is too low. Just move it up so it's just below the water surface with the jets pointing slightly upwards, or place it above the water line with the jets pointing slightly down. It needs to be positioned so that the flow breaks the water surface.

I might need to get a couple of suckers to hold it a bit higher, there is a vertical tube near the top which I thought I might be able to remove before the angle but I'm not sure if it will fit together then.
