Leak from filling loop tap, combi boiler

spratley

I had to top up the boiler pressure a little bit today, but as I opened the tap, a bit of water came out, at the base of the tap itself. I turned the tap off, but it is still dripping, though very slowly. I think that a new filling loop is probably in order. I see that they are sold at the local DIY sheds, but is it a DIY job, or get a plumber in? I'm fairly good at most DIY, but my efforts at plumbing are usually not very successful!

The filling loops I've used have all been short flexi-hoses. If yours is like that, it should be simple to swap.

Make sure both taps are off (one at each end). Undo the nuts that hold the hose on. Unplug the old hose and plug in the new one. Do the nuts up again.

In theory, you are supposed to remove the hose every time you have finished topping up the system, but nobody ever does.

Why would you "make sure that both taps are off (one at each end)" when these taps will be replaced when a new filling loop is fitted?

The OP states that water leaked from the base of the tap, so replacing the removable flexi hose alone will not cure a leaking valve.
