- regarding the questions about why the hot water from the tap would at firs
- flow quite rapidly, then reduce in intensity, while the cold water didn't...
-
- There are a number of things going on.
-
- 1) There may be different piping systems, particularly if the building has
- undergone renovation. While steel pipes have very little pressure related
- expansion (at least with thepressures normally encountered), plastic
- piping will have somewhat more.
-
- 2) There may be air in the system. This will deifinitely compress under
- pressure, thus giving extra push when a valve is first opened.
-
- 3) The water heater tank may have a bladder or similar expandable
- container in it.
-
- 4) there may be an extra "booster" pump on the heated water line which
- added a bit of pressure which gave an extra push when the water is first
- turned on.
