underfloor heating. one section not heating.

[una]

Problem with activator in just one area of the UFH system. I don't know how to take off the activator to check the pin. No problem with water flow. Not sure how to handle the flex coming out of the activator. I know the pins aren't working as the water gauges are not responding (that's what you see through the glass). The system is over 10 years old and the activators are Henco. Wouldn't be trying to fix this myself, but getting help from outside is probably not possible while we have the Corona virus. Thanks

A lot of them have a ring nut screwed into manifold that the actuator clips into. Before trying to remove actuator make sure the system is electrically isolated

Usually the actuators are held in place by a female threaded metal ring screwed onto the outlet of each zone on the manifold, isolate electrically push down the actuator and unscrew the ring anti clockwise , post a picture please , and all of us here at PF wish you a speedy recovery . Regards Kop
