changing of pipes is the conclusion

Answer 2

Explanation:

When we observe any leak in the water supply line we can see the water fountain from the leaking joint of pipes of the main water supply line. It proves that water exerts pressure or force on the wall of water pipes so that water comes out from the leaking joints.

Like water, all liquids exert pressure on wall of container that is why due to leakage the water fountain will come out with high force.
