I just did some experimenting on both Baja and on TC1 and here's what I found:
On both Baja and TC1, you can still stand just outside the bakery shop to the south of the Bottled Imp alchemy shop in New Haven (stand under the eaves) and fill your empty water pitchers from the water trough inside the bakery shop. If you are decide to run back to the bank and need to refill a water pitcher, as long as you haven't actually targetted some other object, you can refill your empty water pitchers if you're standing on the west side of the New Haven Bank by clicking on the empty water pitcher and then using a "Last Target" macro.
While working on cooking, you can also refill your pitchers from oh maybe one or possibly two houses away from the trough inside your own house by doing the same thing (i.e., click on the empty pitcher and then use your "Last Target" macro), as long as you haven't been targeting something else. Get too far away from the bakery shop's trough or your house's trough, and the trough is no longer recognized as the "last target." Even if you go up a few floors in your own house or moveto the other side of the inside of your house, you can still refill a water pitcher by clicking it and the using a Last Target macro.
You can also do this with ponds, such as the one next to the Zento bank or by the Zento stable, but the distance you can remove yourself from the pond before using the "Last Target" macro is measured in mere tiles.
Trying to refill a water pitcher while standing on the shore seems to have become difficult, if not impossible on TC1. Waves that used to work are now too far away to reach, and even the water next to you is too far away if your character's feet and the water are not on the same level.
If you are tending plants, you can refill a water pitcher from a water trough inside your house as long as your character can target at least a corner of the wooden frame of the water trough while still on the house plot. Clicking the pitcher and then using a "Last Target" macro of course won't work because one of your plant pots would be stored as the last target.
Some outdoor water troughs (e.g., at SOME public stables) are also still functional for filling up water pitchers while tending plants, as long as you can target some part of the frame of the water trough after clicking on an empty pitcher. However, if you want to use the outdoor water troughs at other similar stables, you have to be practically on top of the trough to take water out of it, even if you have a direct line of sight to the trough and there are no fences or other barriers in the way. For example, to use the troughs at the Zento stables, you have to stand practically on top of them. However, you can be almost off screen from the troughs at the Bucking Horse Stables in west Brit and still fill a water pitcher. Same goes for the troughs in the pen near the Skara Brae stable. The troughs at the Delucia, Luna and Umbra stables seem to be for appearance only--get too far away and you are told you're too far away to use them. Stand right next to them and they don't work at all. (I don't think the nonfunctional troughs are a new issue...I think many of them have never worked for as long as I've been playing.)
Totally unrelated but perhaps of interest for decorators is that you can still pick up many of the large and half barrels at stables on TC1 by emptying them (or if already empty and nonstealable, dumping in a pitcher of water and them emptying it).
Edited to add: Going to try reaching some waves in a boat on TC1 and see if the message that it is too far away still shows up and if the waves will still refill a pitcher.
Well, you can get to the waves in a boat and they will refill a pitcher if you're close enough. But, as expected, you can only fill the pitcher one time. You get the message, "Can't pour it there" if you click on a full pitcher and then click on a wave.
The screen shot below shows four wave caps close to the boat. The two to the left were useable and so was the closest one on the right. However, the one farthest away on the right (circled in red) was too far away to use while standing as shown in the boat.
