Having read Ed Siretts sealed heating system FAQ (cheers Ed), I'm
assuming our Ferroli Optima 901 has a faulty pressure release valve
as it needs topping up everyday.

I topped up to ~2 bar, and noticed the discharge pipe started
dripping, which pretty much confirms a faulty pressure release valve,
right??

A possible solution that Ed suggests, short of getting a new valve,
is to "dislodge dirt on the valve by operating the test knob (often
red plastic) very briefly".

However, I can't fing my test knob! Is this inside the boiler,
attached to the valve? I really have no idea about boilers. What
would be the procedure for getting to the test knob?

Don't know this model, but normally the relief valve has a red lever that
you lift up a bit to let water out.
You should be able to locate the valve because the vent pipe should
connect
directly to it.
BTW the installer should have left you the install and user manuals for
the
boiler...

Thanks,

I haven't got the manuals, so I'll take the cover off and have a poke
round...

Cheers,

Ted
