If you really get concerned, you can always talk to your doctor about it.
For what it's worth, my younger daughter wasn't interested in locomotion for a long time. There wasn't anything wrong with her - she was just happy as she was. She was almost nine months old before she even started rolling seriously. Her older siblings, who were watching her while I was in the other room for a minute, said, "Come look!" and the girl had rolled from the middle of the living room floor to underneath the Christmas tree, and was checking out the ornaments on the bottom row.
She finally decided, long after her first birthday, that standing was worth her time, but she didn't start walking until she was sixteen months old - just a couple of weeks before her baby brother arrived. By the calendar, this is way after her siblings did these things.
Now she's a schoolteacher, so we figure she's made up her lost time.
It isn't unusual for a baby to try to do something and then not try again for a while. Sometimes the new movement happens the first few times almost by accident, as it were. Then the child thinks (I'm sure of it), "Hmmm... *how* did I do that again?" and she has to figure it out. Or she'll find something else to interest her and put off the new movement.
My older grandson (15 months old) is a take-your-time kid. He started taking a step or two, and then would think, "Well, that's enough for today," and go back to the more efficient crawling. Then he'd do a little more, and once more go back to the old standby. There was no inability; he just didn't have the motivation. For some reason, his decision to walk full-time came at about the same time he got his first haircut! Maybe the weight of all that hair on his head was keeping him down. :^) At any rate, he's done everything in his own good time - which is a little behind "the norm," but is fine for him.
Oh, and there's nothing unusual about a fourteen-month-old turning on the water works. It's something they do well at that age. It's a phase they go through.
