    Stopped system,removed and cleaned the mixing valve,ut was blocked by some thick solid black dirt. Flushed the water too,until from a dark scarry black to a clean clear colour. Installed one of those magnetic dual filters.


    Did u flush the entire system and did u do it yourself I am thinking of flushing mine and am fearful I will have air locks when done. Is there an easy method for flushing under floor heating ?

    No,I had a plumber with me.
    Connected the system to the pressure pump,got 3bars in and let water flow trough the rads and ufh for minutes,until water came clean.

    I have an automatic aif flow for dealing with the air and i had to vent the rads later myself.

    Nothing serious,max one hour.
    I recommend doing it every summer,flush full system.
