I need to flush my CH system and the only drain valve I can find is above the boiler on the inlet side. The boiler is at the mid point of the house so half the rads will be below that point, just releasing the water from this point wouldn't really help would it?
How can I ensure a full flush without any specialist pumping equpment?
Will filling emptying, and cycling repeatedly eventually flush the system or will sludge etc be left at the bottom of the system?
