TTonygeek replied to the thread Bypass valve.So, I have cleaned all the internals of the old DU144 bypass valve and all now moves beautifully freely. Not that easy to remove what...
-
TTonygeek replied to the thread Bypass valve.Meanwhile, I have been thinking that I don't actually know how much flow is occurring through the ABV. All I know is that flow...

TTonygeek replied to the thread Bypass valve.Thank you John. Yes, I will try to set up the cleaned old valve in my rig and test at what pressure it opens. Watch this space! May...

TTonygeek replied to the thread Bypass valve.Hi again John. I can’t see anything in the Installation and Maintenance Instructions about the HEx head loss. The only thing in the...
-
TTonygeek replied to the thread Bypass valve.Thanks John. I'll have a look in the instructions. Yes, it does seem strange that they are not sensing the real flow temperature more...

TTonygeek replied to the thread Bypass valve.Hi John. I’m afraid I didn’t see your message earlier, as the engineers arrived just before 7.30am. They have just left after...

TTonygeek replied to the thread Bypass valve.Hi Johntheo5. Boiler has been running for a while (heating only) so I’ve taken some readings at pump setting 2, ie 200mb. Target flow...

TTonygeek replied to the thread Bypass valve.Thank you Johntheo5. I will also respond further later today. The pump is currently on 200mb but can easily be changed. However, the...
