Sliplining is a technique for repairing leaks or restoring structural stability to an existing pipeline. It involves installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends. Sliplining has been used since the 1940s.
Henrico's water main on Staples Mill Road dates to the 1950s, and had had emergency repairs completed on it many times in the 18 months before the outage. During these repairs, officials had been able to replace leaking valves and install new valves, better allowing them to close off sections of the pipe if necessary. [23]

If there is a leak in one of the tubes of a shell and tube heat exchanger, that tube can be plugged at both ends with specially sized plugs to isolate the leak. This is done in the plenum(s) at the points ...
A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines..
