Why didn't they just try to retrieve the water they lost?
In S1E2 "Water", the Battlestar's water tanks are sabotaged and water is blown out into space.
I was expecting the plot to be along the lines of how to retrieve this water. After all it must have frozen and be near the ship. That isn't mentioned, and the story is about hunting out a new source of water.
I've not found any comments behind this. Why did they need to seek a new source of water? Is it a plot hole, or am I missing something?

Why would it be near the ship?
It would be travelling away, spreading wider as it went, at the same speed as when it blew out.
It would be a slightly more difficult task than throwing a handful of ball-bearings from the top of the Empire State Building, then running down to the street to go find them.
Edit:
Let me add some weight to this initially rather flippant answer, which was based entirely on the misconception that the water would still be "right there".
The initial explosion would have imparted some considerable velocity to the water.
Liquid water [presumably initially at something like room temperature] when exposed to a vacuum will immediately boil away [violently], so now we're chasing after 'steam'.
Think of steam pushing out of a kettle spout, but with no guided direction & a million times more powerful.- That steam, now exposed to something approaching absolute zero or -273°C will almost instantly turn to ice.
- We now have microscopic ice, travelling at the initial velocity imparted by the blast, plus the additional velocity generated as it turned from liquid to gas, spreading outward in a vast, ever-expanding cloud.
The speed will never decrease in a vacuum, as there is no friction to slow it down. It will stop when it hits something or is drawn into a gravity well, otherwise it will carry on pretty much forever. - They do not have the resources to even attempt to go catch all that 'ice mist'.
- & this is a big 6. They are running from the Cylons. There's a war on & they are losing badly.

Why did Mars lose its water?
Based on data gathered by NASA's Mars Atmosphere and Volatile Evolution (MAVEN), scientists suggest that dust storms rising from the Martian surface appear to have been slowly sucking away the planet's water over the course of millions of years, sweeping water molecules up on a wild journey into the atmosphere.How long can you survive stranded at sea?

As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this. Factors that may change how much water a person needs include: age.Why Didn't You Stop Me?

Answer 2
Because the cylons are coming.
If Galactica and the fleet stay in one place (or are in an easily predictable place) the cylons will find them and kill them. So they have to keep running, which means leaving the water behind.
