I'm wondering if there is a clever way of replacing a stuck trv valve (tried hammer, but no better) without draining down my system which has just been filled with Fernox Protector. It's a ground floor kitchen with tiled floor and only 6 inches of accessible pipe above the floor. Boiler is in utility room next to the kitchen. It's a big system with 20 rads over 3 floors. Ground floor is on a separate zone.
I'm assuming that freezing will not work so close to the valve and with Protector in the system. Am I right?
By the way, it's a weird TRV - when you take the head off, the sprung pin in the valve body pulls inwards to close the valve, rather than pushes outwards against the head mechanism. I've not seen that before. I'll replace it with a normal one I think.
Many thanks in anticipation
