I've got a gravity feed y-plan CH and DW system that has had some radiators fitted. Its got a combined feed and vent.
I've had x400 in the system for the past 3 weeks, and have drain and flushed it all out, was nice and clean.
All radiators other than the towel rail and the one in the room with the room thermostat have TRVs.
When the CH turns on, you can her the glug of "I've still got air in me", before the system then settles down.
If I run just the DW I get the same effect, however after 10-15 minutes there is a lot of gurgling going on, unlike when just the CH is on.
The towel radiator turns on with either CH or DW so I assume it is connected to the primaries. I have to bleed this radiator when ever the DW has been on.
During my investigations, I've noticed that there is a 15mm pipe teed off from between the pump and the mid-point valve. This then goes down into the wall (All of my useful to know pipes go into the wall...) where I am assuming it joins the return.
I'm assuming this is a bypass line, that really should have a valve(Manual or auto) but doesn't.
Would I be correct in assuming because this pipe bypasses the system, I'm more likely to have difficulty getting out any air locks in the system? Should I add a valve here to aid me with bleeding the system?
Best Wishes
