Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as orthometric heights.
The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level".
Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment.

Hi
I wonder if anyone could help me with a simple problem please.
The upper part of my sink tap has come loose and I can't figure out how to get to the nut/screw to tighten it. It looks as though the top cap should come off but it doesn't want to and I don't want to force it. It's a Bristan...

Can anyone advise if it is feasible to move these pipes below floor level or if they are like this for a reason (picture 1)?

I always run the hot pipe above cold when running pipes horizontal, to stop any heat transfer but for a 2 foot section I am unable to do this. Will this be a major problem the hot running below the cold for this small section?

A builder has asked me to put the ufh manifold in the basement which will then feed the ground floor (the pipes will all be above the manifold)
I think that any manifold MUST go above pipe loops for air bubble/airlock prevention what say you guys????
