They are inaccurate. True water clocks were based on water flowing into or out of a graduated container and the user could tell the time by looking at the graduation aligned with the water level. There were also pseudo water-clocks in which a pendulum kept time but the power was provided by water.
True water clocks, whether of the inflow or outflow variety, required a steady rate of flow. This depends on the viscosity of water which is dependent on the ambient temperature. A change in temperature from 20 to 21 deg C produces a change in viscosity of approx 2%. This would cause a clock to lose half an hour in a day!

What is the Disadvantage of water clocks?
One disadvantage of water clocks is that they are prone to leakage, which can affect the accuracy of timekeeping. Additionally, water clocks require regular maintenance and monitoring to ensure they are functioning properly.
Are water clocks used today?
Water clocks are not commonly used today as they have been replaced by more accurate timekeeping devices such as wristwatches, smartphones, and digital clocks. Water clocks were used in ancient times to measure time by tracking the flow of water from one container to another.
What type of clocks did people make when there was no electricity or wires?
Before electricity, people made mechanical clocks that were powered by weights or springs. These clocks used gears, escapements, and pendulums to keep time accurately. Sundials and water clocks were other types of timekeeping devices used before the invention of electricity.
What was the clock after water clock?
Oh, dude, the water clock was like the OG clock, you know? It was all about water flowing and telling time way back in ancient times. Then came the good ol' mechanical clocks, like the cuckoo clocks and grandfather clocks. So, technically, the water clock was like the grandpa of all clocks!
When were the first kind of mechanical clocks introduced?
The first mechanical clocks were introduced in the 14th century. These early clocks were weight-driven and used gears and escapements to regulate the movement of the hands. Prior to this, timekeeping devices were primarily sundials or water clocks.
Who used water clocks?
I think all egyptians used water clocks.
Did they set sun clocks and water clocks back?
Sun clocks were adjusted by moving the position of the gnomon to account for the changing angle of sunlight, while water clocks were recalibrated by adjusting the flow rate of water through the mechanism.

What were water clocks used for?
Keeping time, in the days before mechanical clocks.
Who was the ancient Greek engineer who made water clocks and movable figures?
Ctesibus was a Greek inventor who made water clocks with moving figures on them.

In order to tell time at night the ancient Egyptians of 3000 BC used?
Water clocks known as clepsydra, which measured time by the flow of water from one container to another. These clocks had markings that indicated the passing hours as the water dripped.

What are disadvanages of water clocks?
The big disadvantage of a water clock in this day and age would be its lack of accuracy compared to present day time pieces. A water clock depends on the speed that water drains through a hole, a function of viscosity. Its viscosity is a function of its density. Water's density varies according to temperature. On a cold day the clock will run slower than on a hot day. While there are places where the ground water temperature remains the same year around, very few people want to go to the trouble of calibrating their own clocks.

Sumerian clocks kept time by using this?
Water.
