Any practical experience of problems with these filling units/keys leaking . And as the bottom cover needs removing I presume one must be GSR
to do this.... All replies gratefully recieved....Rob Foster aka centralheatking
 
If you’re talking about the slot on plastic cover on the base of these boilers to expose the key “hole” then no you don’t need to be GS. The key design is carp however and often leak
 
ok so the bottom bit is not classified as 'taking the cover off a gas appliance ' because the products of combustion are not contained in this area of the boiler, but the plastic key thing is rubbish ..as I thought
regards Rob
 
Worcester now sell a keyless filling loop which is much better. It's just a lever with two check valves built in. Fits in place of the crappy keyed version.
 
Will fit any place that has the key with the white knob
 
So brand new 25 & 30 ng WB models are ok and have none of the previous problems ...associated with the silly key
thing ? thanks for anymore input Rob Foster
 
it's an improvement on the keyed filling loop. It's easy to top up systems but a pain when filling from empty. The lever springs back to the closed position, so you end up locking it open with a screwdriver! I still prefer an external loop.
 
I know what your saying. I think they got it approval based on it having a check valve on both the cold and return side. The lever spring closes so it cannot be left in the open position.
 
that contravenes water regulations but hey vaillant do it as well as the rest of the country

So how does your unit comply if not check valves ?
 
So wras G24.1 G24.2 and wras
B54 are redundant , thats ok as long as everbody is singing off the same hymm sheet
