For instance, a 6'' manufactured wye connection
with a 4" lateral pipe will result in a large void space and thus more residual grout.
With an easy to use hand drill and drill guide, a watertight wye connection
can be achieved in just a few minutes saving the contractor time and money.
The lateral sealing process uses three bladders to isolate the wye connection - two in the mainline, on each side of the wye, and one in the lateral.
After installation, the crew uses TV inspection equipment to examine the repaired pipe and deploy a remote-controlled pneumatic cutter to open up the wye connections to the active house laterals.
