Recently isolated some of my CH system and fully drained the hot and cold water systems and now one of the header tank over flows is dripping (right onto conservatory roof like a drum!!) whats likey to be the reason for it to have started just after I had done the work I needed to do? and which...

The fact that you can here the motor in the actuator turning is not conclusive proof its turning the spindle in the valve ,I recently had the same problem but in reverse ,hot water ,no heating found i neede to change the valve body as well as the motorhead or actuator

I have just had a similar problem ,my rads were getting hot when the hot water was on . I was able to establish the motorised valve was the problem by takeing the moter head off the valve and switching between rads and hot water and I could see the motor was turning . Deduced that the actual...

Mission accomplished with some minor mopping up ,which i could have avoided if I had realise the pipe that comes from the emmersion is capable of being turned up wards so allowing the excees water to go back in. Ah well lesson learned and a few quid saved . :D

When you say drain the system do you mean the emmersion tank until its below the level of the valve ?surely if I dont turn off the mains it will just refill as I run the hot taps off? As I say i am confident that I can isolate the pipe on the pump side and I am guessing (hoping nothing will...

I need to change a motorised valve body . Its in the airing cupboard on the upstairs landing . I am trying to work out if i can avoid a complete draining of my CH system ,as far as I can see there are three 22mm pipes going into the body (its a three port mid position ??) 1 pipe goes straight...

Hmmm :cry: Spokee too soon its stuck again ,is there anything will free it up (WD40)or the like ? or perhaps just some gentle turning back and forth ? If the brass valve needs changing is that a full system drain ?

Don't want to speak too soon but looks like you guys know your stuff!!! Turned the spindle with my pliers and then put the actuator back on and it now seems to be ok . Cant say for certain as the rads need to cool enough for me to know for sure that the wont get hot when the hot waters on...

That would make sense the way our lass cram stuff in the cupboard

Beginning to think that but just laid out some hard earned cash and as a Yorkishire man that hurts !! Just unscrewed the actuator and switched on the heating and the centre of the actuar moved round and the pump fired up which wasnt happening with actuator in place ,any ideas?

Re wiring ,should be ,I just changed the controller 1 for one so didnt touch the wiring . The house is about 12 years old and most people on the estate will tell you they have changed a couple of actuators at least ,this is my third !!!! I have always suspected that the programmer gets...

I have a problem with my CH whereby all of a sudden the heating wont come on at all when it should but the rads do get hot when the water heating is on . The system is controlled by a combination of the above . I changed the actuator because for a while the problem could be cured by giving it...
