Baxi 105e - Unable to attach FIlling Loop Hose

[redmen1892]

Hi All,

I suspect that this is a real 'dumb' question.

I bleed some of the radiators last night as i normally do in readiness for the CH going on, some of the rads are more prone to encountering trapped air than others.

After which I noticed the pressure on the boiler was almost at zero, I must of been too eager!

I remembered that after my last service the engineer removed the filling loop, it had been permanently connected ever since we moved in and at the last service I asked him whether it should of been disconnected due to regs.

He duly removed the hose and capped off the cold water inlet and CH return valves and left me with the hose.

I now find that I cannot securely connect the hose to the return valve as the casing of the boiler prevents the wheel nut from turning (see picture), in addition the cold water inlet valve tap is very close to end of the filling loop thread which makes it very difficult to position the filling hose , i'm assuming that if I open up the water inlet valve tap to make a bigger gap then water will start coming into the system or does the Double Check valve prevent this?

I have no idea how the hose was originally fitted, as far as I'm aware its the same filling loop hose and its the same stop valves.

I'm stumped as how i can fit the filling loop, i'm sure the answer is easy and I am just being blindsided by something.

Any ideas?

Many thanks Jon

1. Jam a large screwdriver or similar between the casing and the wing nut and create enough space. Don't overdo it and damage the boiler.
2. Screw a 1/2" tap extension (e.g. BES No. 10222) to the male thread of the valve, which should give you clearance to screw wing nut to other end of extension.

you just need to push the loop into the valve then tighten the finger tight nut, in your pic that is not located you need to push the loop in properly, then remove the cap on the other one and do the same, then open the valves till boiler shows between 1.0 Bar and 1.5 Bar when cold

Thanks, think i'll go for #2, seems less prone to potential damage.

Thanks Ian, the trouble is i cannot tighten the wing nut by hand as it jams into casing of the boiler, the loop is in as far as it will go without exerting undue pressure, i cannot fathom how it was originally connected

or:
3. Cut all or part of the wings off the offending nut and tighten with grips.

Slacken this nut about a quarter turn (a little bit of water may come out, so put a towel under it) then gently move the filling loop valve down a bit and tighten the nut back up and then you are good to go

@ianmc I think the OP is talking about the top wing nut and that the wings on the nut are catching the grey section of the frame?

The OP could still do as Ian says and if the wings of the nut still hits on the boiler casing, he could just get a filler hose with no wings on the nuts. Just checked and my one doesn’t have wing nuts.

Yes rob I know that , but if he moves the other end down and uses big boy hands, the other one will move in easily enough to attach the hose

Ah right Ian, apols, I had to look twice to see the top was was catching on the grey angle of the case, was just in case .
