Prevention is better than cure you never know when the chaos might occur. Triola Plumbing offers earthquake valve installation so that you and your house will be safe during the disaster. We install earthquake-sensitive gas shut-off valves. They are intended to close in the event of an earthquake to prevent gas flow into a structure where earthquake damage may have occurred. This will greatly reduce the potential risk of explosion or fire due to loss of gas line integrity or uncontrolled flow of gas after a major earthquake.
