One of the dangers of having your business in a building that you own yourself is that you have large periods of time where the building is unoccupied. This can spell disaster in many different scenarios. Take for example if there were to be a serious leak from a pipi in the building. On average, the pressure in the pipes is about 14 gallons per minute, so you can just imagine how quickly this can turn into a catastrophe.
Any time there is work done on the pipes or appliances that are connected to water, you want to make sure that it is done properly with no chance of leaking. A sloppy plumbing job could end up costing you thousands in repairs.
It is also important that any cuts that are done into the walls are far away from pipes. A nicked pipe is a small beginning, but with the combination of water, pressure, and time, it could turn really bad.
