Filling loop on baxi due tec 28

[goofy gorilla]

Hey guys how do I fill boiler with water, pressure went low after I bled a few radiators..I see 2 tap like things at the top and the loop has 2 inline isolating valves..when I open the inline isolating valves , nothing happens?

Are you opening BOTH isolation valves ? They both need to be open at the same time. Your loop doesn't appear to have a check valve ,and should be replaced with one that does.

Yes opening both at the same time..no water going into boiler..??

One of them must be blocked ,probably the one on the heating pipe ,or knackered.
You could remove the flexi from one valve ,then open one valve a little ,to see if water flows,then try the other.
Which ever valve gives no water is the duff one.

Is it just me, or does the Flexi look badly kinked?

Is it just me, or does the Flexi look badly kinked?

Aye, could be slightly, and depending on the water pressure available, might not be able to overcome this.

All good , opened the two taps at the top as well, filled up the boiler..a tad too much water but it's in the green.. there is no kink in the flexi pipe just the way pic was taken..anyway all good now..cheers
