A leaking pipe is likely to cause water damage to your home. You need to identify the symptoms of a leaking pipe and take action accordingly. The water level in the tub has been increasing since last week, when you first noticed it. The toilet seems to be overflowing more often than usual, and there is a puddle on the floor near the back door. You have seen water dripping from your ceiling for weeks now, which you thought was just condensation from your air conditioner until this morning when you woke up to find that there was a leak in your ceiling as well. A leaking pipe can also cause mold growth and structural damage if left unattended for too long.
