Friendly reminder: Check your plumbing!

[sphelps]

I see, it sounded like you were describing an actual burst pipe which seemed unlikely is all. While I agree checking plumbing may not be a bad idea I don't feel it's necessary when done properly. 90% of the plumbing in your home is concealed behind walls or other obstacles making checking virtually impossible without destroying something. This plumbing is put under much higher pressure and temperature loads than our aquariums yet it lasts for decades without issue if done correctly.

A better suggestion would be doing things right the first time to avoid devastating failures that can ruin your home. Using silicone to attach hoses to pumps is a bad idea and, as you now know, likely to fail. Using appropriate hose clamps or hard glued PVC fittings is the proper way to do things.
