    Refilling underfloor heating

    Hi, gotta a bit of an issue with refilling my underfloor heating. Am I right in saying that the flow meters along the manifold should be on the top rail, but as you can see they are at the bottom? Also have I got to loosen off the electrical actuators at the top to refill the system? Cheers
