Curlybonce Posted November 4, 2020 Share Posted November 4, 2020 Hello - I'm hoping somebody can help with a problem we have with an underfloor heating manifold (Rifeng). It seems that all the red flow meters are stuck and a couple don't have any water in them although the heating is working. No matter how much they're opened or closed they stay the same. Does anyone know why this is or what we should do to make them move. What we've done instead is open them up fully and then use the blue actuators to adjust the flow but obviously we don't know if we've got them open too much or not enough. Any help would be appreciated. Link to comment Share on other sites More sharing options...
LA3222 Posted November 4, 2020 Share Posted November 4, 2020 I have one like this on my manifold and I seem to recall looking it this a while back. I'm sure I saw somewhere that they can be disassembled to sort out however I havent gotten around to doing so yet. I think I was looking at the Wunda site for docs on how to do this.

Curlybonce Posted November 4, 2020 Author Share Posted November 4, 2020 We did take one off but it seems to be a sealed unit and the glass doesn't come out and there wasn't anything obviously wrong with it. Thanks. Link to comment Share on other sites More sharing options...
