Need to replace the rubber washer where the filling loop connects the iso valve (can't stop it dripping )on the return side under the boiler. Can I do this by draining just the boiler or do I need to drain all the system down? (Baxi Duo-tech 28 HE A)
leak on the filling loop connector

So it's just the flow and return iso valves on the boiler off and that's it?
Are they special washers or any rubber washer.
Thank's Theweeknd

A pic would help.
Are you saying that it is leaking at the end of the braided hose that goes from one valve on the cold water main to the other valve that's connected to the flow/return pipe on the boiler? Are both black valve taps at 90deg to the pipe direction?

It's like this the copper 90-degree bend leaking on the brass nut that is screwed to the return iso valve on the right
The copper end is like this I did change it about 12 month ago when I was changing a rad but I drained down the system.
don't want to do that if I can get away just draining the boiler. I tried the iso valve but water still came out.

You need a fibre washer on that fitting to make the seal.
If the isolator will not close the supply to that elbow then drain down.

Any 15mm washer will do doesnt need to be rubber, fibre washers are more reliable than rubber
Thanks, guys just watched a youtube video I have now drained the boiler turned all iso valves off and opened the white drain valve on the boiler not much water loss this is the washer that was leaking so I will replace with a fibre one.
Thank's again

Careful then, if you replaced that a year ago then you have overtightened it, causing the washer to become damaged.
It just needs to be finger tight then 1/4 to 1/2 a turn and that should be plenty.

That is why Fibre ones are more reliable , but they can be over tightened too
