3 port valve upside down

[rssteve]

are they ok to mount with the in pipe facing up, so the actuator will be on the bottom?

in pipe being flow from boiler?
if this is at the bottom then its fine.
not really a prob how its mounted.

 

[rssteve]

well the flow from the boiler is coming out the concrete floor, up. across for about 200mm, combined feed and vent attached here going up to loft. then the pipe goes down through pump and into 3 port valve.

pain to work on if its too close to the floor.

 

[rssteve]

no its about 800mm off the ground.

Usually no.

The gland packing starts to leak after some years of use and you do not want the water to drip into the electric actuator. Read the manufacturer's installation instructions.

agreed.
its not difficult to alter the orientation.

One wonders why you dont want to follow the manufacturers instructions.

If its an open vented system the the lower pressure willl make leaking less likely than on a sealed system.

However, one wonders why anyone would consider fitting one in a less reliable position.

Would i have asked the question if i didn;t have dealts? The only reason i questioned it, is because it would save piping up from the floor, upto vent and feed, then back down with the pump somewhere, then up again into the bottom of 3 port valve.

 

[spacethegas]

can you post a diagram of what you propose as it does not sound right.

 

[rssteve]

ok here goes.

i tried uploading it twice to this website but it just appears black. any ideas?

You do not need the bypass valve. In fact it will never do its work as one port in the motorised valve is always open.

Cannot see anything else wrong in the drawing
