Can't Find My Filling Loop!

[Straker]

Hi All,

I have a Vaillant Ecotec Turbomax Pro 28E. Have lost pressure through a radiator bleeding session but am unable to fathom how to repressurise. I have read numerous posts on this but none seem to exactly describe my boiler. There is even a tutorial on YouTube but again the model demonstrated is slightly different.

I assumed my boiler did not have a built in filling loop so I purchased the braided hose thingy. I have taken a series of pictures of the underneath of the boiler which I will try to attach. Can anyone clarify which screws I should undo or where (if) I need to use the hose.

Well, it's not there!!!

It should be accessible somewhere though!!!

You'll have to hunt around for it as it's probably hidden at the back of a cupboard or behind a unit or somewhere like that. It'll be a metal coloured braided hose with a sort of winged nut at each end. One end will be connected to the 15mm cold water inlet so if you follow that pipe you should find it somewhere.

Best of luck!!!

Hi,
follow the cold supply to boiler and heating return.
You will see some means of connecting the hose, there may be chrome caps covering the valve 't'.

Thanks for your response dontknowitall. I understand that the Vaillant Turbomax Pro doesn't have an integrated filling loop hence why I purchased the braided hose myself. Just haven't got a clue where I should be attaching the thing. Anyone familiar with this model boiler? Read somwhere that two screws need undoing but I have tried all combinations under the boiler and nothing seems to be working.

These boilers have external filling loops. There will be one fitted somewhere, probably not too far. Don't bother trying undoing any screws or nuts. That will do you no good.
If you can't find it phone a plumber. He will find it and top it up for you. It won't cost much and you will know where it is done from for future ref.

mine was under the boiler on the cold water pipe as above, and it was attached by a non-return valve and isolation valves,.

 

[dontknowitall]

Usually it's in a place where you can see the gauge as you fill the system, so it shouldn't be too far away.

never assume it was fitted well lol

concerned about these screw you have tried

It should be quite obvious when you see it

trace that pipe marked cold mains until you hit a valve
