Hi, we had underfloor heating installed in our self-build home about 15 years ago. Some of the actuator valves are now leaking and we need to replace them. I'm trying to source some that fit. The plastic caps which came with the originals had the 'Watts' brand on. I've tried ordering a couple of the most common valves and the pin is too long (they bottom out in the manifold as you're screwing them in). Any ideas where I can find replacements please? Is there such a thing as an actuator with adjustable depth? I will try to attach a couple of pics to show manifold and actuator valve measurements. Very grateful for any help.
