Hi David, Yes the water can be felt moving through the lower fbh hose. I have been in email and phone contact with Devilish and Trebor and even they are unsure what the issue is. I have a few tests to carry out that they suggested but due to the weather here and my m.o.t today I havnt had a chance yet. Thanks for your reply and as always I'll post up any results or fingers crossed a solution. Lee.
I'd also like to thank Devilish and Trebor for their help and advice
