Drayton Drain Easy Kit works on open vented systems provided the F/E tank is no more than 30ft above the TRV.
Make sure you open the bleed screw on the rad until no more water comes out - this will show that a vacuum has been set up in the pipework - then shut the bleed screw. Also close the lockshield valve (count turns!) before removing the TRV.
I have done this many times and never had any spillage. You see the water bobbing up and down in the flow pipe. Just be careful you do not lose the pipe through the floor boards.
It's what you can't see, that gets you!
Suppose the nut's thread is different and the olive's squashed into the pipe, which has also been kinked, as they often are?
The valve is quite new though so im hoping all is ok.
the problem is that the previous owners had sumhow managed to snap the plastic valve clean off! i am holding it!!
we have been in the house for 7mths now and there have been no probs, we have just left it alone, but due to a bit of high pressure(which has been sorted), it has managed to find a hole in the top of the valve and is now starting to leak.
i have unscrewed knurled ring that the plastic top was originally attached to......i only need this part! no mucking around with the rest as i originally thought.
bit worried why it was leaking though!! will fix a new top and see what happens!!
