Water pressure in apartment (2nd floor in two floor building) lower since new pipes and new shower
It's quite likely that one shower fixture might well deliver less water (gallons per minute) than another one. This change might save your landlords a good deal of money over a number of buildings, especially if they are paying for the water heating.
Since you are in a rental, and you have a shower that works, whether or not it works exactly as it used to, your option is to move when your lease is up, or not. You are not describing a &quot;problem&quot; you could reasonably expect to break a lease over, or have your landlords change.
