We are leasing a house, an a pipe just broke that flooded the house?

Damage to the building is covered under the homeowner's insurance policy. Damage to contents (furniture, etc) is covered under renter's insurance.

First, you did the right thing if you could not get in touch with the owner by calling a plumber because you as a tenant must take responsibility by trying to minimize the damages. Try to do the best you can to stop the bleeding of the water damage.

Second, the cause of the pipe breaking is very important. How did it happened? and/or did someone cause the pipe to break. Remember, pipes normally do not break on there own unless they freeze or are improperly installed. Normally, the plumber can dissect the problem and if was not caused by you make sure you get it in writing from the plumber.

Third, the owner is not responsible for your personal belongings, that what renters insurance is for. They are normally required to carry at least fire insurance if they have a lien on the building.

Nevertheless, if the damages turn out to be an act of nature like frozen pipes and you cannot prove that the landlord did not properly insulate and that was the cause then you could have a difficult time recovering losses.

It is important that you find the source of incident. remember to document and take pictures of everything, including were the pipe broke.

The pipes r lanlord problems, butt your property is on you thats what renters insurance is for. Sorry

If you call a plumber, charge it to the landlord. It is definitely their responsibility. You should still call your landlord again and if they still don't answer, hire the plumber and charge it to them.
