    Two port zone valve on cylinder return

    Come across some of these recently, usually only ever see them on the flow to the cylinder, not on the return from it. Any reason for this? Does it make any difference as still won't be any flow unless there is a call from the cylinder stat?

    Sunvic 3 port valve

    Hi ... I'm changing a 3 port Sunvic valve (MK1453). I've read that instead of replacing the body you can replace just the inners as this is held by 4 screws. If this is possible, will the system need to be drained first or is there a 'shortcut' ? Thanks in advance for any replies.

    Heating zoned on a three port

    Hi. Went to a job where they wanted a new thermostat for the downstairs as it wasn't working properly. Having looked at the controls it was a 2 zone system where they'd used a 3 port to differentiate between them. Bizarre. Anyone seen this before?
