Hi Sean
You are a star !!!!! I had to purge it 3 times, it turned over for about 5mins then cut out again, i repeated it abou 4 times and it's running a treat, the only issue is that tha pump is still a bit noisy, i hope this will calm down a bit as it gets rid of all the air.
You've put my faith back in Landys.
Many thanks
Darren
