Thanks for accepting us on this great static forum, learnt a lot already as I have been scrolling through the many queries & answers. The posts re the floe drain down system is particularly good, I have just been isolating the water, draining each tap, shower & wc's, I had heard about pressurising the system with compressed air but was unsure how to go about it,what psi being my main concern, so will be looking into this system.
